One of the most unintuitive things I have ever experienced is the fact that Microsoft Publisher saves printer settings (paper size, tray, paper type, colour etc) within the *.pub file, which confuses the hell out of users who would not be expecting that. For example, if you open up a text document, image, photo, PDF or hundreds of other types of files the printer settings would all be the same, but then if you opened a Publisher document that a previous user decided to print in black and white then it would print….in black and white! Worse, if you chose a document, made a copy of it and saved as a new document it will inherit the print properties of the original document, which of course you wouldn’t have a clue as to what settings were set. How random is that???
