bob, what hp printers have you used? sadly, they're not built like they used to be, but if you buy the cheapest thing you see at office depot, you're bound to suffer, regardless of the name on them (and that is coming from a former hp repairman with lots of crappy printers under his belt that happened to typically be the same models).
in my experience, hp printer software is a little iffy on the whole, when it is a winprinter, but when an hp printer flakes out, it is usually repairable, whereas when canon/epson/lexmark inkjets flake out, you buy a new printer. this is less the rule these days with the cheapo office depot deals, where most printers are disposable. just my 2 cents.
arranger, the hp photosmart printers look pretty crisp with expensive-ass photo paper, but if you want a quality glossy look, you're not going to spend much more having a professional printer print out nice copies of your designs. i would probably print my own cd insets, but i can get absurd deals in printer paper/cartridges/etc.
my #1 advice for printing with inkjets of any brand is DO NOT REFILL YOUR CARTRIDGES. go to a shop that has seen hundreds of printers with refilled exploded cartridges that gunk up the electronics/feed drive and you will see why.
