Just wanted to post a heads-up. There is a conflict between Microsoft's update KB951748 and ZoneAlarm. Something about that update will cause ZoneAlarm to block your browsers from internet access and ultimately shut your connection down. ZoneAlarm is recommending that you uninstall this update as a fix for right now. Turning your ZoneAlarm setting down to "medium" will also fix this problem, but obviously will reduce the level of security provided by the program.
For printing, sure. If you're done working with your source document and have no further edits...then convert it to PDF and you're done. It should be the same on all machines. That's the beauty of PDF. In theory, at least.
