1. You didn't write about the margins in the Windows XP print options. This is NOT in the PM 17 program. Here's a picture of the left printable margin -> https://iapps.courts.state.ny.us/cdr/userdocs/images/browsers/ffmargins.png (and others.)

Sorry but as printers can install other dialogs, you will have to share yours for me to comment on your printer.

2. CHEAT. Go get a PDF printer like PDF995 and print to the PDF and then print the PDF to the printer with new margins.
