printing quality

[Micha Feigin]

I have a problem with printing quality under debian.
I am using an epson lx 300 dot matrix printer (i know that windows it can
work also as epson lx800 lx810 jx80 - i may be missing a bit on the
letters).
the problem is that under linux when not printing unformated text ot from
netscape i get horible results (including ps from other sources).
If anyone can tell me how to solve the problem, and/or what filter to use
under magicfilter.
thanx
