When I installed it before there were some included instructions and I followed those. Presumably they are now out of date. I'll try that page in a day or two, when I have time for a decent session. However, I did give yum the command for all those dependencies, and it did find some that I didn't have already, but after that hp-check still listed these: Checking PyQt 4.x version... error: NOT FOUND OR FAILED TO LOAD! Checking for dependency: CUPS DDK - CUPS driver development kit... warning: NOT FOUND! This is an OPTIONAL/RUNTIME ONLY dependency.
