Since I switched to Snow Leopard I was not satisfied with the printing drivers for my old HP OfficeJet 95. I used the included Gutenprint drivers. For text they worked ok, but images looked terrible.
Today I decided to do something about it. From Linux I know that HPLIP has some pretty good driver (hpijs) for most HP Devices. Fortunately I can use the same drivers for Mac OS X to. You need three packages to do this. More information can be found on the website of the Linux Foundation.

This should help you get your old HP Printer working.

I needed this one! Thanks a lot, finally I found it!
Thank you so much for this info! It works fine in Lion as well
Hi Geert, I`ve noticed that you`ve been able to install this drivers in Lion, i wonder if you be so kind to email me the files you used to install, since the links to download them are down, i`ll be very thankful
