Since this morning, I can't print in full size portrait. No matter how I fiddle the printing options, reboot the computer, restart the printer, the hard copy always comes out half size, 2 pages per sheet side. This happens when I use LibreOffice Writer, Gedit or when printing PDF documents. I have seen a few questions about this topic but none of the solutions corrected the situation.
I am running on Xubuntu 14.04 and my printer is Canon Pixma MP180

did you control those variable, as I ask in the previous comment?
Ok, I finally decided to delete the printer and re-add it and it corrected the issue.
I solved the same problem unchecking the "Auto Rotate and Center" option.
