I think it was after I updated to version 1.8.0 that this started happening. No matter what print view I have selected, when I go to print my plot, the view changes to actual size (I think), or something very large. No matter what size I set my plot view on, it still changes when I try to print.
There is a popup menu button in the Inspector's Document tab right below the Document Size fields. There are two options in this menu that control printing. One is an option to always scale printing so it fits a single page. The other allows printing at the current zoom setting.
