Printing bugs are hard to diagnose because each printer has a different printer driver, so the same file can print well on one printer and not print on another printer.
That's why when reporting printing bugs in, please make sure to include the following information:
  • version of Sumatra
  • version of the OS (e.g. windows 7, windows 10 etc.)
  • name of the printer
  • can you open and see the file in Sumatra?
  • what exactly happens, are there any error messages?
  • if it happens only for some files but not the others
    • is there anything different about the files that don't print that jumps out?
    • please attach the file that doesn't print to bug report. If the file is confidential you can e-mail it to (Krzysztof Kowalczyk, Sumatra's main developer).
