I'm having a weird problem here. I've noticed someone else has submitted this problem before and there was no solution given. The problem is "a"s become "b"s and 1s become 2s for every character. Spaces become "!"s. We never have the problem viewing it, it is only on print outs. Also if you try enough times you will eventually get a correct printout. We are printing from a windows 2000, adobe acrobat reader 7 (downloaded and installed in last 2 weeks - should be most uptodate) to an HP LJ 4250n with a PCL6 driver. I tried switching it to a PS driver, but all printouts (not just pdfs) printed inverted (black background, white text, and mirrored!). It also didn't solve the problem - I got a black, mirrored, and garbled pdf printout. I need to solve the improper printing problem, so any help you can provide would be much appriciated. Thanks

Edit for a bump! Please help! thx
