We are having the same issues. HP Laserjet 200 M276 has been working fine then suddenly it spits out blank pages when trying to print PDF's.
All other files/pages print fine; it is just PDF's that are blank.
OS is XP SP3, latest Adobe reader 11.06, latest firmware from HP site.
Printing via USB
We have also set the "print as image" option in the advanced menu in print menu and it makes no difference.
Some input from HP would be helpful.
