Had some trouble printing from Open Office Writer (an open-source word processor). Didn’t seem to matter what setting I changed, it didn’t fit on the page properly.
I even contacted Canon who emailed me some steps to follow. It was around then that I figured out it was printing fine from other applications, just not from Open Office!
Fortunately, Open Office lets you “Save as a PDF” – so that’s my temporary solution… Save the document as a PDF, and then print that.
Hopefully the next update will fix that little bug.
