| And this scenario does not only serve for cheap DIY solutions to save old printers, it also can be a base for cost-effective printer firmware development. | And this scenario does not only serve for cheap DIY solutions to save old printers, it also can be a base for cost-effective printer firmware development. | ||
| - | This project is about investigating whether one could run the components of the free software printing stack, as CUPS, PAPPL, libcupsfilters, ... under the Zephyr operating system, and actually let this tiny print server execute printer drivers and print on legacy printers. Also the handling of print data and the need of resources here needs to be investigated. Can we hold several pages? Can we use Ghostscript? Or do we have to stream raster print data from the client to the printer? | + | This project is about investigating whether one could run the components of the free software printing stack, as [[https://openprinting.github.io/cups|CUPS]], [[https://github.com/michaelrsweet/pappl/|PAPPL]], [[https://github.com/OpenPrinting/libcupsfilters|libcupsfilters]], ... under the Zephyr operating system, and actually let this tiny print server execute printer drivers and print on legacy printers.

| Most desirable is to do this with PAPPL (Printer APPlication Library), as it is designed to emulate a driverless IPP printer in software, including the so-called "Gadget" mode to appear as an IPP-over-USB device when connecting the power supply USB port of the SBC with the client computer's USB. | Most desirable is to do this with PAPPL (Printer APPlication Library), as it is designed to emulate a driverless IPP printer in software, including the so-called "Gadget" mode to appear as an IPP-over-USB device when connecting the power supply USB port of the SBC with the client computer's USB. | ||

| To prevent man-in-the-middle attacks between a client and a network IPP printer with encrypted connection, the first time when a new network printer is accessed, the printer's certificate is loaded from the printer and saved locally. On subsequent accesses the printer's certificate is compared to the locally saved one and on mismatch the error is logged and the printing does not happen. | To prevent man-in-the-middle attacks between a client and a network IPP printer with encrypted connection, the first time when a new network printer is accessed, the printer's certificate is loaded from the printer and saved locally.

Then theuser screams on internet platforms, ehen they are lucky finds information about this problem and how to remove the old certificate to make the CUPS replace it by the current one and the printer print again. | + | often this happens without an attack, just on a change of the printer configuration or a printer firmware update.
