I am trying to print a document from MS Office using the Windows 8 trial OS. I get a message saying it can't print. I am trying to print to my wireless Canon MX 870. There was no problem with Windows 7. In the Mac's Systems preference for printers I get a message saying that Postscript can't be translated. In windows, there is now explanation. The control panel printer section says the printer is working correctly. But it clearly isn't. Any ideas?? anyone? I am using Mt Lion OS. thanks, Larry
