HP printer issue

Currently, we are running about 7 networked HP Laserjet 4050TN and 4000 printers. We keep having this problem where the printer will seemingly randomly cut off the bottom 2.67 inches of the page. It’s not a margins issue, as the printing literally cuts lines of text in half.

My questions is this: has anyone heard of this problem before. I’ve been an admin here for about 2 months now, and the previous admins have encountered the problem as well, but never got around to trying to get it fixed.

Any ideas.

Your input if appreciated.
