Steps to reproduce the problem:
1. Try to print but missing tray selection options

What is the expected behavior?
I'd see all the trays available.

What went wrong?
There isn't an option to show all the trays for my Color LaserJet Enterprise MFP M577dn or the HP Color LaserJet Pro MFP M281fdw printers.   This seems to be true of any HP Laserjet models which makes the Chrome OS difficult to use in an office environment.

Did this work before? N/A
