This is true, the printout looks ugly like I am seeing on my monitor. I am
on Fedora 12, and use the print menu of my evince tool to print out the
file. Is there a special method to print eps files?

See the last comparison screenshot:

And these are settings that I enabled while creating this plots. (Plus for
the png I used 600 dpi)

# ps backend params
ps.papersize      : auto   # auto, letter, legal, ledger, A0-A10, B0-B10

ps.usedistiller   : xpdf    # can be: None, ghostscript or xpdf
ps.distiller.res  : 6000      # dpi
ps.fonttype       : 42         # Output Type 3 (Type3) or Type 42 (TrueType)

# pdf backend params
pdf.compression   : 0 # integer from 0 to 9
pdf.fonttype       : 42         # Output Type 3 (Type3) or Type 42
(TrueType)

PNG with high resolution produces the nicest looking plot. PDF follows it.
However EPS file still looks ugly. What are your font suggestions? An any
ideas why ps.distiller.res has no effect on the produced plot?

Could somebody reproduce the similar results?

Thanks.
