Dear MacRumors users, I've been searching the web and experimenting for hours and I seem to be unable to solve my problem. I am trying to print from OSX contacts onto envelopes. My printer is a hp laserjet 100 color mfp m175nw and I am on OSX 10.9.2 . Every time I try to print envelopes from contacts, it scale the envelope to be a full 8.5x11 sheet. The envelopes are 5.25x7.25 and there is no preset for that size. Even when I select a standard paper size that is something close, it will either rotate the page the wrong direction or scale it to 8.5x11. This seems like ti should be supra easy and yet I struggled with the same thing on this printer trying to print 5x7 photos (another paper size that is not standard on this printer). I also tried editing the printer setup to no avail as it seems incapable of selecting custom size even thought he dialog box suggest that it can. Anybody got suggestions?
