The first device should fail scanning and this is substantiated by the four error lines referring to attrubutes in Message #7. A workaround would be to have a section headed [icejet_pro_8500_a910] in models.dat.
The second device should work on HPLIP 3.19.3. This is indicated also by there being only two error lines in Message #7.
If there is anything else going on over and above #1797501, I am afraid my skills are not up to diagnosing it and offering a solution. It is the province of upstream to produce fix.
Thank you for the level of detail, Dirk. We have
> ty=Officejet Pro 8500 A910
and
> ty=HP OfficeJet Pro 8730
