Home / Printing with Sumatra causes a line at the left of the page
Certainly Unusual ( just ran two print sets but neither had a line on last page)
I have never seen a similar problem.
This type of problem is best reported as issue at https://github.com/sumatrapdfreader/sumatrapdf/issues
What will be asked there by me is which version of SumatraPDF causes that result and provide a sample file with the default printer page size e.g. is it A4 Paper and is input undersized in width are you using command line or Priner dialog and in either case what options were chosen.
