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.
