I looked into printing from the Reader.

Android apps don't seem to have a "Print" menu item. Instead they use "Share", which allows you to send stuff from one app to other apps, including PrinterShare which can then "print" it. Apps like the Browser have a "Share" option, but the Reader doesn't, so you can't "print" from the Reader directly. Instead, you can "Save as PDF", and then use the PrinterShare app to find and "print" the PDF.

In other words, DRM vis-a-vis remote printers doesn't come into it, I think. If the DRM file allows you to save a page to PDF, that PDF is unprotected and can be sent anywhere.
