I now use pnm2ppa on my macpro/osx v 10.4.11 to print on my hp 722c deskjet. Works great!
But the maintenance functions, including cartridge alignment, provided by HP's original win95 driver do not appear to be available.
Alignment isn't currently a problem (at least not noticibly), but it still seems like a good idea when I put in a new cartridge.
Anyone out there know of anything that'll do this?
