Apps
If you have been trying out Chromebooks and need to do a task for which on your Windows/Mac laptop you have specific software -- despair not. The site, aboutchromebook.com, provides information on Chromebook apps or online apps to accomplish those tasks. It's a good place to start, but do not be surprised if you hit inaccurate entries. A very good place to check for online apps (for any computer, not just Chromebook) is TechSupportAlert.com
Printing
To enable printing, you need to setup Google's Cloud Print. To do this (one-time) setup, use the Chrome browser on a PC/Mac that can access the desired printer. Follow the instructions enable the Google Cloud Print connector. How do you print? See Print a page or the how-to video at youtu.be/8fPR5A2pg3k.

Microsoft Word
If you need to edit Word documents, read Office Document Editor for Chromebooks
