Steps to reproduce the problem:
1. Add a native printer in Chrome OS
2. Select HP as the manufacturer and then look at the list of models. 
3. The list contains very old models and nothing from the last few years.

What is the expected behavior?
I would expect to see printers and MFPs from the last few years listed. Like the HP Color LaserJet Enterprise MFP M577dn or the HP Color LaserJet Pro MFP M281fdw. In Ubuntu I can at least use the M577dn without any issues but moving over the PPD file doesn't work as Chrome OS says it's invalid.

What went wrong?
All you see are very old models with no current models listed.  What happens then is that you can only use the generic entry which gives you no options for tray control.

Did this work before? N/A
