Today I came across a weird #printer problem. From #Debian #Linux I could print to the #Canon PIXMA printer in simplex or #duplex.
BUT, in duplex mode it would print a side, eject the paper, re-load the paper, then eject it again without printing anything on it, and then start the second page on a separate sheet of paper.
This happened from my PC and a separate one using the stock #IPP driver in #CUPS
Annoyingly it works perfectly in Windows...
