Usually, a printer's Print options settings will override the application's Print output settings. Check your printer's menu options/print settings to ensure that it is set for 100% and is not scaling or aligning the print job. The printer itself could be scaling/sizing the print job. There are 2 fairly common possibilities I can think of off the top of my head.ġ.
