Tray/InputSource setting is ignored

[kristianlm]

Hi, and thanks for making printing on Linux a pleasant experience. I have a fix for an issue with my HP printer, but I don't know if this is the right forum to report this. I have an HP Color LaserJet M750 that works well on my Arch Linux distro, with the exception of tray selection. I installed the drivers through the cups webadmin on port 631 and added my new printer.

I ran into a problem where the printer would ignore my Paper Source / Tray selection choice in the print dialog. The below changes seems to fix this problem.

I hope this can is the right place to report this and hope it can be integrated into this generated driverless cups-filters driver.
