I intend to submit the following tomorrow for inclusion in the Debian 11 Release Notes. Please feel free to comment on its accuracy or quality of expression if necessary. ======================================================================== The Release Notes for Debian 10 briefly described the driverless printing situation implemented via CUPS and cups-filters. The changes applied to modern printers connected by ethernet or wireless. https://www.debian.org/releases/stable/amd64/release-notes/ch-whats-new.en.html#driverless-printing The release of Debian 11 sees the inclusion of ipp-usb into the stable archive. ipp-usb is recommended by cups-daemon and utilises the vendor-neutral IPP-over-USB protocol that is supported by many modern printers. ipp-usb allows a USB device to be seen and treated as a network device. The outcome is that driverless printing is extended to include USB connected printers. The specifics are outlined at https://wiki.debian.org/CUPSDriverlessPrinting. The systemd service file included in ipp-usb starts the ipp-usb daemon when a printer is plugged in, making a USB connected printer available for printing to, either by being auto-setup by cups-browsed or being manually installed with a driverless print queue. The use of vendor printer drivers, free and non-free, becomes unnecessary. ======================================================================== Cheers, Brian.
