I know this is not exactly what you are looking for, but if you are always printing to the same format, you could define a new format with the windows print management with a 10mm margin on the left.
no, that’s not exactly what I need - I print to A4. Here’s my scenario: We use a business software to generate offers, invoices etc. Sometimes we print directly to paper, which already has the heading on it, sometimes we print to PDF combining the print output from our software with an existing PDF which contains the heading into one document (I use a modified AddWatermark script to do that). So far so god.
Unfortunately the print output from our business software comes with 10 mm offset on the left when printing to paper, but without that offset when printing to pdf. Don’t ask me why! To get identical results I could work with an offset added by pdfcreator when using my “print to headed paper” profile… Do you get the picture?
