printer driver for HP Color LaserJet 35xx/36xx

 HP's Color LaserJets 35xx and 36xx are supported by HP's HPIJS driver
 (part of HPLIP), but HPIJS supports only the lowest quality level of
 the three which are available under Windows. This driver which is not
 developed at HP but by an independent developer, supports all modes and
 so provides the highest printout quality for these printers.
