I have a weird problem with a Canon MF227dw. Sometimes certain documents (mostly PDFs) do not print: the printer just beeps as it normally does after finishing printing, but with no other visible actions (e.g., sheets are not fed from the tray, and I don't hear the printer warming up). I'm using a Mac and I tried both from Preview and Adobe Reader. No error is displayed on the computer or the printer. I tried both with wireless printing and connecting the printer directly via USB. I tried restarting the printer and resetting the printing system on my Mac. It happens only on specific documents, and I found no way to print them on that printer. The same documents print on different printers (I tried on Xerox printers, HP and Toshiba) from the same computer.
Today I downloaded three scientific papers from the same source (a conference website) and I can't print any of them. So there must be something offending in the documents (they are all formatted in the same way, coming from the same source), but I can't figure out what's wrong. Any suggestions?
