More printer drivers

Hi,

A dumb PostScript printer driver is in the repository.
It supports monochrome and color printing.
Color printing requires about 24 times more space
than monochrome printing in the output not in
memory!
The printer driver is not usable for PS file creation, 
because it creates very large files depending on the 
chosen dpi.

A PCL6 printer driver is also in the repository.
It supports monochrome printing only and is
untested and it's very likely that it does not work.

BTW has anybody documentation for a printer
language called PCLGUI? My HP DeskJet 3816
seems to use this for color printing.
