Vardhaman:
Printing to XPS and OpenXPS has the same problem.
Suzanne:
I went through all the settings again.
• Header and Footer, both wre set to 0cm. Adjusting the values to 1cm made no differenceto the problem.
• Scale content for A4 or 8.5 x 11" paper sizes was selected, however when I deselected it, the result was the same.
Doug:
Thanks, I will send you the document as well as the PDF, to show the final output.
INTERESTING:
When I changed the fonts to Arial, the PDF printed correctly!
The 2 custom fonts I used, are both .otf
Both of these are high quality commercial fonts.
I've never had a problem with regards to spacing, margins and layout using these custom fonts in earlier editions of Word or other software applications (used them in Excel 2016 and Photoshop CC 2015).
