That's perfectly fine by me. I'm sorry if you felt my messages as pressure towards adding printing in the upcoming release, that wasn't my purpose. 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.

Mac OS X's printing architecture is built on top of CUPS, which has been purchased by Apple a few years back. The command line tool lp is included


There are probably OS X frameworks integrating this with an interface, or maybe Qt does this, but on such areas I must confess my total ignorance.
