About 80% of the time when I try to print a PDF, or even to a printer for that matter, the printing scale changes on me. If I have several views to print from one drawing I have to tell it the same scale over and over; it won't keep the same scale as the most recent print. Is there a setting I don't know about?
I find the most reliable method on my PC is to select my Inkjet printer* first and the desired "preference" as if I wanted a paper-print; then select the .PDF-printer and "print". Otherwise I find going direct to the PDF-printer problematic. I have my "preferences" saved for letter-size and 11x17" plot sized. My full-size document is a 11x17" inkjet original on-paper in "B&W-only" to save color ink, ...I rarely actually print in color. For construction drawings I find that the std.-quality ink-saver mode is dark-enough. My normal letter-sized business printouts and drafts typically are one-or-two sided "draft"-quality B&W-only in ink-saver mode.
