I have two printers in my office, the primary being a Lexmark X543 Laser. For a couple of months now I've been noticing that whenever I print to the X543 from my Macbook Pro wirelessly via my network the copy is getting pushed up the page about 50-60mm chopping the top of the page off. Upgrading to Mountain Lion hasn't stopped this, neither has downloading the latest drivers to both the Macbook and the iMac that the X543 is usb connected to. If I connect the X543 directly to the Macbook the problem resolves itself, reconnect it back to the iMac and it reverts. I recently changed my network provider by going from basic Sky to BT Fibre Optic, and that seems, coincidentally or otherwise, to be about when the problem began. Printing wirelessly from Macbook to my other printer (Epson inkjet) has no issues. Any ideas out there please? Thank you.
