Hello,

i got a ip4600 from canon and i compiled gutenprint from the latest snapshot i got.
I made a cd tray that has the same measurements as the original one(it's a G tray) but instead of a round cutout i have a square one for pcb's. h:130mm/w:100mm
The printer is accepting my tray without any issues and printing on it but everything outside the round mask is missing.
After playing a bit in the sourcecode with functions like cd_mask inside print_canon.c i still have the issue that the printed area is cropped to a round shape.

My question is now, how can i mod the source to remove the mask from my tray? Is the mask inside the printer firmware and could i trick it to print the whole area?
Or is it simply a function i didn't find as of yet?

Thanks for any input and ideas, i am a bit stuck here.
