What about using GhostScript, which, I think, is available 
on all systems.
The menu command could launch it, perhaps after offering a 
dialog box to select the pages, printer,...

I don't know about the quality of printing using specific fonts.

Here I was just reacting to the presentation of TeXworks as just another PDF viewer, as opposed to an integrated TeX GUI. It's perfectly fine that it doesn't include printing yet, or continuous scrolling. Better omit something IMHO than offer it half-baked and inconsistent, it can be added later when it's ready for all platforms. That was the point of my original message: make sure the patch is omitted in official builds if it's not available for all platforms.
