Question

i'm a developer, i want to write driver for Canon IP2780, i had known GARO UFR. but i want to konw which PDL Canon IP2780 can support ?

like HP printer, i can find which PDL it can support, but i fond nothing about Canon printer.

such as HP Deskjet 1000, it support PCL3 GUI.

i also ask Canon, but no answer so far.

i fond this 《Canon Understanding PDLs》,but it is about imagePROGRAF printer not PIXMA.

Answer 1

Run sudo /usr/lib/cups/backup/usb get device_id of the printer.

device_id will show which PDL is supported.
