Ok, embarrassing, there must be an easy way - I have a Core Data model diagram that I want to print - printing is easy, but it pushes it over 4 pages which is difficult to c
I ran into the same problem described above, where the zoom didn't really seem to work well much below about 70-80%. I found that if (in XCode 4) you go to File->Page Setup, then choose a different size of paper that the model will fit onto 1 page (I chose A3). Then go to File->Print but instead of printing the document, choose "Save PDF". Then view the resulting PDF file using Preview, and print from there: Preview will allow you to scale the image in the Print dialog so that it fits on whatever size paper your printer supports.
