I have tried out this driver, on a machine with installed ESP
GhostScript 8.15.x (with "opvp" device) and foomatic-rip, and CUPS one
does the usual "./configure; make; make install", restarts CUPS and sets
up a queue (for example with the web interface). Unfortunately, I do not
have a CLJ 4600 or 5500 and had to try it on the LaserJet 4050, a bw
printer. Here all what is not white gets printed in black but otherwise
the printout is OK. Would this driver work also on a pure PCL-5c/5e
printer (older HP LaserJets). Can the driver easily be expanded to bw
printers and to 1200 dpi?

Please tell me when there is a version with translated comments, so I
can recommend this code to people asking me how to do best to write a

Yes, soon the recommended driver for the HPs will be the one from Epson.
