Yes I also have the impression that it has something to do with the
translation from PostScript to PCL. The printer prints 10ppm from my
laptop with Windows2000, so it can't be a hardware problem. I think it has
to be a driver issue, some difference of printing systems between

I tried the "pxlmono" driver, recommended on the site instead of the
"lj5mono" or "lj5gray" I'm using now. But that driver didn't work at all.
Thanks for the tip though.

I'm thinking of looking for a Postscript emulator DIMM now, to make my
printer a PS printer.
