I have my Default Windows Printer preferences set to print 'B' size.
When I print from Creo 4.0 M050 (also set to 'B' size within ), after selecting 'Print' I have to manually set Printer properties to 'B' size every time. (I did not have to do this in previous versions of Pro/E prior to Creo 4.0)
Every other software picks up the system default settings (ex. MS Word, Adobe, Paint,etc), except for Pro/E. See attached Image.
