barline thickness

[Francisco Vila]

Here I attach two samples scanned from paper. Details below. My
question is simply: am I the only person with this problem? Others
would be, Is lilypond generating wrong PDFs? Is my printer wrong? Is
ubuntu gutsy evince wrongly printing PDFs?

Details:

laserjet-png.png comes from a PNG generated by LilyPond with the --png
-dresolution=600 commandline options.

laserjet-pdf.png comes from a PDF generated by LilyPond.

Both images are printed on a laserjet P2015dn at the default
resolution (FastRes). This is 600dpi I think. Then I scanned the
printed papers at 300 dpi.

Clearly the PDF has a barline MUCH thicker than the PNG and it's not a
matter of resolution (other vertical lines look fine).

Thank you. My workaround these days is to generate and print only
PNGs, but windows users also report this problem in other systems and
printers.
