HP is enhancing the Linux printing experience by delivering a softwre solution that provides very good print quality. The HP driver provides printing support for more than 30 Deskjet printer models. The driver supports two print modes - plain paper normal, and photopaper best.
The HP driver uses GPL Ghostscript to convert PostScript into print rasters that are passed through shared memory to our driver that executes as a server. A Ghostscript update kit is included with the HP solution.
