| 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.
