[pdftex] problem with printing

[The Thanh Han]

Hi all,

I have to print a few pdf files on windows 98, printer HPLJ5L. When I set
the graphic resolution in printer properties to 600, then those pdfs are
printed ugly, part of pages are printed at very low resolution. When the
resolution is set to 300, this problem disappeared. Is it because the
printer doesn't have enough memory? How ca I fix it?

TIA,
Thanh
