As someone who would like printing capability, but is a heavy user of RW nevertheless, I highly recommend that you consider RW unless you absolutely have be able to print.
The only time that I can see absolutely needing printing ability is if you are at a location where you don't have access to electric outlets (some conventions and game stores). If you DM from home or a friend's home, I would think you could manage to have a laptop at the table.
RW is the best TTRPG campaign-management system available and it would be great if you could use it to manage campaigns and prepare sessions that you actually DM from printed paper. Even if it had printing capability, however, I couldn't imagine going back to page flipping when I have an entire campaign database at my fingertips.
If you are are thinking about the occasional need to print player handouts, you can attach those to topics and articles as PDF (or Word, RTF, etc.) files, which you can open and print from the associated software (Adobe Acrobat, MS Word, etc.).
I know that there are some who just won't use RW if they can't print, because they have to DM from paper, but those of us among the vocal users of RW asking for print functionality have been running games for quite a while without the ability to print.
