SumatraPDF new features: March 20, 2026

New in the SumatraPDF pre-release builds: Detailed printer info and custom paper sizes -enum-printers (alias -list-printers) now works in release builds and shows much more: driver, status, defaults, paper sizes, resolutions and more. -print-settings accepts custom paper sizes, e.g. paper=76mm x 130mm. Selectable text in Document Properties The Document Properties window shows its information in a text box, so you can select and copy any part of it. About shows 32-bit builds The About window says when you’re running the 32-bit version. Changes for this day · Full changelog
