I've been freelancing in book production for over 25 years and file imaging for some 14 years.
The particular OS is not important.
In terms of importance, the following are the key factors:
1. What your printer (and/or imager) expects to receive
2. Clean postscript or Adobe Acrobat (for Acrobat, fonts embedded).
3. If you've a Mac, odds should allow--if you want--to send the native application (i.e., InDesign) file
Note: All color images should be 4 color: CYMK. No RGB.
Note 2: For fonts, only postscript. No truetype.
Good luck,

And what about some proffesional use. At work I'm using Photoshop, Corel Draw and InDesign (top three) and I'm preparing thing to be printed. Which OS (let's narrow the choice to XP and 2000) would you suggest. I've heard that with XP I can encounter troubles when printing to file for external service shop - but I have no personal experience with that (I hope I made myself clear enough as I'm not very familiar with english terminology in that field). The cost of OS is not an issue - it'll not be paid by me but by my boss :-)TIA Maciej
