Printing bugs are hard to diagnose because each printer has a different driver, so the same file may print correctly on one printer but not on another.
When reporting printing bugs in the issue tracker, please include the following information:
- version of Sumatra
- version of the OS (e.g. Windows Vista or Windows 10)
- name of the printer
- can you open and see the file in Sumatra?
- what exactly happens, and 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 the bug report. If the file is confidential, you can email it to [email protected] (Krzysztof Kowalczyk, SumatraPDF’s main developer).
