The new paper sizes are available in the HPIJS entry onopenprinting.org or in the CVS version Foomatic.
If you need special paper sizes, support for custom paper
sizes is in HPIJS 1.3.1. For example, for 20 cm x 10cm uselpr -o PageSize=Custom.20x10cm file.ps or
lpr -o PageSize=Custom.200x100mm file.ps
For 5 inches x 7.5 inches:
lpr -o PageSize=Custom.5x7.5in file.ps
The Photo settings of the Resolution option are
optimized for glossy photo paper. The Color andGrayscale settings for normal, non-glossy paper. Most not too
old printers auto-detect the paper type in most modes.
Earlier versions of HPIJS lack support for custom paper
sizes. Either update to a current version of HPIJS/HPLIP or Set up a
second print queue for your printer using Gimp-Print (model selection:HP DeskJet 900 series or pcl-900), and print the
envelopes through the Gimp-Print queue.
If this does not work, OpenOffice.org might be producing broken PostScript for envelopes. Report this bug to the developer mailing list or bug tracking system on the OpenOffice.org web site.
Use the HP Toolbox of the HPLIP package.
Alternatively, there is also libinklevel onhttp://freshmeat.net/projects/libinklevel/
Here is another method:
If you cut and paste the simple C program from here:https://sourceforge.net/forum/message.php?msg_id=1574175
and compile it according to the instructions:gcc -O2 -o lpdevid lpdevid.c then you will have a tool
that will return the device ID of your printer.
The results look like:
$ lpdevid /dev/usb/lp0 MFG:HEWLETT-PACKARD;MDL:DESKJET .920C;CMD:MLC,PCL,PML;CLASS:PRINTER;DESCRIPTION:Hewlett-Packard DeskJet .920C;SERN:XXXXXXXXXXXX;VSTATUS:$HB0$NC0,ff,DN,IDLE,CUT,K0,C0,SM,NR,KP003,CP048;VP:0800,FL,B0;VJ:
This result shows that 3% of black ink, and 48% of colour remains.
Look for the KP and CP settings.
Not all printers return such a helpful string. There was a discussion about this here:https://sourceforge.net/forum/message.php?msg_id=1749891
You can download the HPIJS and HPLIP source at the project's main site:http://hpinkjet.sourceforge.net/
Older HP inkjets cannot print on the last half inch (1.27 cm) of the paper. The mechanics of the printer restrict it from printing, and it cannot be changed in software.
Newer models have two paper tractions (one before and one after the print heads) and they can print on the full area of the paper. HPLIP is required to get this to work.
At the moment, there is no one working on this. In wine, this is unlikely to happen because wine does not provide 32-bit driver support.
supports also PCL 5/5e laser printers, and it has much better grayscales. You can also try Gimp-Print/Gutenprint 4.2.4 or newer (with “Fast” or “Very Fast” dithering mode). If you have GhostScript
8.x or newer, set the dithering algorithm to Well-Tempered Screening (current Foomatic monochrome PCL laser printers have an appropriate option).
The too light images are fixed in HPIJS 1.3. Install 1.3 or the current 1.3.1 (which also adds custom paper sizes).
Your apsfilter version only supports the old HPIJS 0.9x. To use the current HPIJS with apsfilter you will probably need to update apsfilter to the current version.
HPIJS 1.3 knows about unprintable margins.
Go to the HPIJS driver page,
and download the PPD files. You will also needfoomatic-db-hpijs and foomatic-db-engine
packages. There was a bug in foomatic-db-engine for using
unprintable margins, so please use the latest version.
Setup the print queues as usual, and applications will take the unprintable margins into account. This will fix the problem with lost text at the borders, when printing with CUPS.
This is not supported in HPIJS 1.4. Use a newer HPIJS/HPLIP or the source code patch from Matthias Bunte.
http://www.openprinting.org/download/printing/hpijs/
As the former patch for HPIJS 1.3 this patch applies to the DeskJet 6xx, 8xx, and most 9xx printers (and compatible multi-function devices) and lets black text being printed with only black ink and not with a mix of all inks. This way ink is saved and the quality gets better.
Please test the patch. See installation instructions on
http://www.openprinting.org/download/printing/hpijs/README.txt
for instructions. Note that from the DeskJet 9xx series only the older-style models without hardware-internal color generation/dithering (HP DeskJet 930C, PSC 950, …) are affected.
This patch is still in testing, please report results to the forum. HP 2500cm
If you don't need to circumvent the 2500CMs slow built-in Postscript RIP, you could either use the HP2600 driver which comes with OS 10.2.x, or create a “generic” Postscript queue using the Mac OS9 HP2500 ppd file. These two drivers should produce the best output.
Look at http://hpoj.sf.net/suplist.shtml and
pretend that your device is a PhotoSmart 7350.
You will probably either need to install the hpoj driver, or upgrade the kernel printer-class driver (printer.c)http://hpoj.sf.net/download.shtml
Try using
ljet3 driver.Windows accesses the printer in a special way, allowing it to process graphics in smaller pieces. This printing mode is not yet supported in free software.
Here are some notes from Rick. The rasterizer in my ancient (circa 1988) Jetroff program could rasterize in chunks to avoid memory/speed problems on really old LaserJets. The code would limit the number of chunks per line to 15 to avoid “ERROR 21”. Any black pixel would start a chunk; sequences of N all white pixels would terminate a chunk. The printer internally uses a display list, and if there are too many items to process once the drum starts turning, then you would get ERROR 21. This code reduced the amount of memory required to hold the page while at the same time avoiding the dreaded ERROR 21. There was still no guarantee that any aribtrary page could be printed, but the domain of printable pages was considerably improved. The maximum number of chunks per line was empirically determined.
I remember scratching my head for a few days before I figured all this out. The technical reference required reading between the lines to understand how the printer works internally.
Here's my old “chunkifier” code from JetRoff, in case some developer finds it useful…

==== Does the HP Jetdirect j2552b support IPP? ====
The Jetdirect card supports the TCP/IP protocol, this is completely
separate from IPP. The machine probably does not support IPP. Use the
socket:// protocol with CUPS.
HP Laserjet 5Si
==== How do I improve greyscale output? ====
Use HPIJS with this printer.
==== How do I use the duplex or tray select features? ====
Use HPIJS, as ljet4.
Laserjet 6L
==== Why is the printed text slightly rotated? ====
A software bug cannot lead to rotated text. Your printer has a
problem with the paper traction.
HP LaserJet 1200
==== Why doesn't the printer print with ptal? ====
When printing to the LaserJet 1200 or 1220 through ptal-printd,
ptal-connect, ptal-print, or ptal-cups (which calls ptal-connect),
you may need to add the -uel switch to the
ptal-{printd,connect,print} command line.
HP LaserJet 1220
==== Why doesn't the printer print with ptal? ====
When printing to the LaserJet 1200 or 1220 through ptal-printd,

you may need to add the -uel switch to the
ptal-{printd,connect,print} command line.
===== HP DesignJet 500 =====
==== How do I print PostScript versions of this printer? ====
If you have the PostScript version, get the PPD file from
Adobe or use the one that's in the driver.
==== How do I print with non-PostScript version? ====
Try one of these
* HP-GL/2 mode: Use the oce9050
* Drivers for other DesignJets: dnj650c
* Gimp-Print: DNJ650C Driver Gimp-Print Gimp-Print-IJS
* DeskJet drivers as HPIJS
HP LaserJet 2200D
==== How do I print with Solaris? ====
Try using an ethernet→parallel printbox (HP JetDirect
or similar). With this you connect the printer to your network and give
it an IP. The spooler can then access it as an LPD server (easiest if
LPD or LPRng is your spooler) or directly (TCP/Socket) on port 9100
(easiest when CUPS is your spooler).

==== How do I set it up to act as a Postscript printer to the entire network? ====
http://mywebpages.comcast.net/heretrythis/hp3100/
HP LaserJet 3150
==== How do I setup SAMBA printer sharing? ====
1. Make DJ3150 shared over network.
2. Create a special user, try printing
3. Set a password.
4. Setup the GNU/Linux boxes to access the printer over Samba using the username and
password.
5. Set a workgroup name in the settings. (Required).
6. Specify the URI
smb://username:password@workgroup/computer/printershare
You will not be able to print across the network without a username
and password.
==== Which driver do I use when printing over the network? ====
* HP Laserjet
* GimpPrint(+IJS)
The GimpPrint driver prints everything as a picture, which
means the output will have a grayish overtone.
HP LaserJet 8150
==== Which PPD do I use? ====
Don't use the PPD from openprinting.org. Use the PPD from
the manufacturer CD-ROM. The recommended file is calledhp8150_7.ppd. There are seven different national languages available.

==== How do I make it print in gimp? ====
Remove the -oraw from the Printing Command
in the printer setup dialog of the GIMP.
HP DeskJet 6122
==== How do I remove the frame around the printout? ====
Follow these instructions:LPDDocumentation
If you do not have a text(and other files)-to-PostScript converter
installed (see above), install one. This is used to print option
documentation for your printer or non-PostScript files, so it's nice to
have it right. If you have more than one converter installed and the one
automatically chosen by lpdomatic is not the desired one, edit the "my
$enscriptcommand = "";" line in the beginning of the lpdomatic script
inserting the name of one of the supported converters ("a2ps",
"enscript", "mpage") between the quotes. To modify the command lines of
the converters or to add support for another converter, edit the lines
following the "my @enscriptcommands =" line.
Switch to mpage as the test-to-PostScript converter
because it does not make frames. Change the
my $enscriptcommand = "";
in lpdomatic to my $enscriptcommand = “mpage”;
Then edit the mpage line aftermy @enscriptcommands =“ as follows:
my @enscriptcommands = ( 'a2ps -1 @@--medium=@@PAGESIZE@@ @@--center-title=@@JOBTITLE@@ -o - 2>/dev/null', 'enscript -G @@-M @@PAGESIZE@@ @@-b "Page $%|@@JOBTITLE@@ -p- 2>/dev/null', 'mpage -o -1 @@-b @@PAGESIZE@@ @@ -P- -' );
The change is to remove the @@-H -h @@JOBTITLE@@. This waympage does not print headlines and you get the pure
text, see man mpage Do not forget to install thempage package on your machine
For the -o docs option note that you must specify an
existing file to avoid lpr waiting for data on standard
input. If you do not have/proc/cpuinfo on your system,
use any other short file. Or try something like (I didn't test it):
echo x | lpr -J docs echo x | lpr -o docs echo x | lpr -Z docs
Here the echo x proivides a VERY small file on standard input and so
this command line does not rely on an existing file in your machine's
file system.
One of the three above-mentioned lines should work, depending on which
flavour of LPD you are using.
Here is the option list in case the docs lines still do not work:
Double-Sided Printing: -o Duplex=<choice> <choice> can be one of the following: DuplexNoTumble (Long Edge (Standard)) DuplexTumble (Short Edge (Flip)) None (Off, default) Page Size: -o PageSize=<choice> <choice> can be one of the following: Letter (Letter, size: 8.50x11.00in, default) A4 (A4, size: 8.26x11.69in) Photo (Photo/4x6 inch index card, size: 4.00x6.00in) PhotoTearOff (Photo with tear-off tab, size: 4.00x6.00in) A5 (A5, size: 5.83x8.26in) A6 (A6, size: 4.12x5.83in) A6TearOff (A6 with tear-off tab, size: 4.12x5.83in) B5JIS (B5 (JIS), size: 7.17x10.12in) Executive (Executive, size: 7.25x10.50in) FLSA (American Foolscap, size: 8.50x13.00in) Hagaki (Hagaki, size: 3.93x5.83in) Legal (Legal, size: 8.50x14.00in) Oufuku (Oufuku-Hagaki, size: 5.83x7.88in) Resolution, Quality, Ink Type, Media Type: -o Resolution=<choice> <choice> can be one of the following: 300BestColorCMYK (300 dpi, Best, Color, Black + Color Cartr.) 300ColorCMYK (300 dpi, Color, Black + Color Cartr., default) 300DraftColorCMYK (300 dpi, Draft, Color, Black + Color Cartr.) 300DraftGrayscaleCMYK (300 dpi, Draft, Grayscale, Black + Color Cartr.) 300GrayscaleCMYK (300 dpi, Grayscale, Black + Color Cartr.) 300PhotoCMYK (300 dpi, Photo, Black + Color Cartr., Photo Paper) 600BestColorCMYK (600 dpi, Best, Color, Black + Color Cartr.) 600GrayscaleCMYK (600 dpi, Grayscale, Black + Color Cartr.) 600PhotoCMYK (600 dpi, Photo, Black + Color Cartr., Photo Paper) 1200PhotoCMYK (1200 dpi, Photo, Black + Color Cartr., Photo Paper)
You have to replace ”-o“ by ”-Z“ or ”-J“ depending on the LPD
which you are running.
==== Is there a simpler way? ====
Use CUPS.
HP PSC 370
==== Why must I power-cycle the printer after every job? ====
Some hpijs versions (after 1.0.3 and through 1.3) are incompatible
with the OfficeJet 600 series products. The symptom is that after
printing an hpijs-generated job, the device must be power-cycled before
it will accept another print job. This issue was fixed in hpijs-1.3.1.

==== What other printing driver may work? ====
It is compatible with the HP Deskjet 930C. You can a driver
for that printer.
HP PSC 1210
==== Does the printer work with GNU/Linux? ====
This machine requires a very recent version of the hpoj and
HPIJS softwares. This printer does not understand PCL. It uses the
LIDIL language, which requires HPIJS (1.3 or newer).http://hpoj.sourceforge.net/suplist.shtmlhttp://hpinkjet.sourceforge.net
You may need libusb.
==== Does the scanner work with GNU/Linux? ====
Scaning works with the CVS version (not 0.90 or earlier) of
the hpoj driver.
You may also need libusb
==== Why can't SANE find the scanner? ====
Try powering the device off and back on.
==== Why is printing so slow? ====
This was a known problem with older version of the HPIJS
software. Please update to version 1.4.1 or later.
==== Why does printing stop when I start scanning? ====
You have to use the current CVS version of HPOJ. See “Bugs and TODO” onhttp://hpoj.sf.net/. Make sure you de-install your current HPOJ
completely before installing the CVS version.
HP PSC 2110
==== Why are the bottom/right margins cut off? ====
==== Why are the scan areas offset to the right? ====
On some models, the margins are cutoff, and the scan area is offset.
The following changes to lib/sane/hpoj.h are reported to help for
some models (PSC 21xx, 22xx, OfficeJet 61xx), but they don't work for
the OfficeJet 1150 and possibly some other models:
* Change SCL_CMD_SET_X_POSITION, SCL_CMD_SET_Y_POSITION, SCL_CMD_SET_X_EXTENT, and SCL_CMD_SET_Y_EXTENT such that the first parameter of the SCL_CMD macro is 'f' instead of 'a'.
* Change DECIPOINTS_PER_INCH from 720 to 300.

==== How do I do borderless printing? ====
lpr -Z PageSize=PhotoTearOff -Z PrintoutMode=Photo file.ps
==== Why does the printer leave a lower border? ====
The printer cannot print full-bleed on the lower border,
therefore HP's photo paper has a tear-off tab.
==== Which alternate driver can I select in CUPS? ====
Try HP DeskJet 990C/hpijs.

==== Why does ptal-hp clock -set cause the clock to stop? ====
Unknown. Setting the clock from the front panel causes
it to get un-stuck. On some but not all units the pre-/un-stuck
clock also drifts quite a bit, and loss of power resets the clock,
but these aren't software issues.
==== Why can't SANE find the scanner? ====
Try powering the device off and back on.
==== Why can't I print with Debian? ====
The Woody version of Debian is not current enough, and
is not compatible with the HP PSC 2210. Try upgrading to thetesting version of Debian.
===== HP OfficeJets =====
==== How do I use the ptal backend? ====
Configure the device ptal-init setup
Restart the CUPS daemon:
killall -HUP cupsd
If it still fails, examine the debug output.
/usr/lib/cups/backend/ptal
This ptal versionhttp://www.openprinting.org/download/printing/ptal
is specific to hpoj-0.8. Use the version that's provided
with hpoj-0.90 instead.
==== Where can I find RedHat 9.0 Setup information? ====
http://cyberelk.net/tim/hpoj.html
==== The following devices are using an obsolete configuration file format. Use ”/etc/rc.d/init.d/hpoj setup“ to delete and re-probe them: ====
This is a bug in RedHat 9.0 version of perl. One workaroudn is to
set the environment variable LANG=C
export LANG=C
or change it in /etc/sysconfig/i18n.
====llioService: llioWrite returns -1, expected=6!? ====
If ptal-init setup fails to configure the device, andptal-mlcd gives an error messagellioService: llioWrite returns -1, expected=6!, and you're using

==== fn(warning: parameter names (without types) in function declaration) compiling ptal-hpjd.c? ====
This is normal.
==== Why am I experiencing errors with my SMP system? ====
SMP (multi-processor) systemsw exhibit data loss, kernel OOPSes,
or complete system lockups with the hpoj software. To work around this,
either boot your system in non-SMP mode, or install libusb and upgrade
to the latest hpoj code in CVS. Also be sure to unload printer.o and
move it out of the /lib/modules tree (renaming isn't enough), to
prevent it from being auto-loaded later due to a hotplug event.
==== Why does the hpoj build fail with RedHat 8.0? ====
To build hpoj-0.90, you can perform one of the following workarounds:
1. Run ./configure –without snmp This disables full-feature
JetDirect support, but locally-connected (parallel-port and USB)
device support is not affected.
2. Edit lib/ptal/Makefile.in and add -DUCD_COMPATIBLE
(without the quote marks) to the CFLAGS line. Then run
./configure --with-snmp=/usr/include/ucd-snmp
====Couldn't find device: llioOpenOne failed!? ====
This error occurs with systems that have devfs. You can work
around this problem by editing the device configuration file in/etc/ptal and changing the lineinit.mlcd.append+=-device to specify the specific possible
device nodes. For example, /dev/usb/lp0, separated by spaces
if more than one USB printer specified, instead of a general wildcard
pattern. Then re-run ptal-init start for the change to take effect.
==== What URI do I use for network printing? ====
Try ipp://the.print.server.address/lp1
==== Why doesn't the PPD file work with Windows 2000? ====
Windows 2000 has a bug which limits it to reading
the options at a maximum of 40 characters per line. This limitation is not
included in the PPD Spec. It is possible to modify the PPD manually, so each line is limited
to 40 characters.
Please contact Microsoft regarding this bug, as we are looking
forward to them providing a speedy resolution to this error.
==== Where can I find instructions for RedHat 9? ====
http://cyberelk.net/tim/hpoj.html
HP OfficeJet G55
==== Why can't I print with the USB port? ====
You're probably trying to print directly to /dev/usb/lp0,
which won't work and tends to get this model into a bad state that
can only be recovered from by power-cycling the device.
For CUPS, you'll print through the CUPSptal backend, not the usb backend.

===== HP 1050C Plotter =====
==== Which Driver do I use? ====
There are two GhostScript drivers which should work.
* OCE9050
* OCE-TDS400.
===== HP 1055CM Plotter =====
==== Which Driver do I use? ====
This printer has Postscript 3 support, but it is pretty poor.
You can get better color output from ghostscript's dnj650c
driver. Like most of HP's large plotters, it can do HPGL rasters
better than Postscript vectors.
The dnj650c driver doesn't seem to be built in most
GNU/Linux distributions.
It is built by default in ESP GhostScript, and is available
out-of-the-box on Mandriva GNU/Linux.
