Sorry if this is a repost, but I don't think my first went through.
We are having problems printing pdf files to our HP color laserjet 4500.
The files we have trouble with are scientific articles downloaded from
the journals (online subscriptions). Some pages of some articles will
print with one or several large black dots (2-4 inches in diameter) on
one or more pages. Happens consistently with that file with the dots
showing up on the same page each time. The dots do not show up when we
print to our HP laserjet 5P. We are printing from Adobe Acrobat 4.05.
Has anyone seen this problem? It never happens with pdf files we create
