[pdftex] Pale print with Adobe Reader

[Rodolfo Medina]

I did:

 $ tex file.tex

and got file.dvi; then

 $ dvips file.dvi -o

and got file.ps; then

 $ ps2pdf file.ps

and got file.pdf. Now, with some printers the print all right; with some it
comes out very pale. If I use pdftex:

 $ pdftex file.tex

, the result is even worse. The same printer prints other pdf files fine.
I need printing my pdf file through MS Windows and Adobe or Acrobat Reader. I
tried all the possible settings and options in the print dialog window with no
result. Any hint? Maybe a way to properly set the brightness/resolution when
creating the pdf file with ps2pdf or with pdftex?

Thanks,
Rodolfo
