I don't use 'print to landscape' in firefox very often and have only just discovered that it's broken in firefox 30.0 to 33.0. The page orientation is OK, but the content is printed top-to-bottom instead of left-to-right. Print preview is correct. This is the case for printing to physical printer or to pdf. Can someone let me know what changes to printing were made in firefox 30.0 - hopefully giving me some clues on tracking this down - may be I need to update some packages? As a work-around, addon 193270, Print Edit v12.8, generates a correct pdf through it's 'Make pdf' function, so I can use that. Still, I would like to know why File|Print from firefox doesn't work.
