What I do is simply do a screen dump and send it to the printer using the excellent print app 'PrintHand'. Screen dump is easy on my Samsung Note 10.1 tablet since that is part of the S-pen features, but there are several apps that can do screen dump.

Installed Skydemon Android on new Samsung Tab S 10.5".  
This tablet is perfect for planning at the airfield but too big for the RV-6a cockpit so I fly with a Skydemon Mobile device fixed in the panel. But having planned I would really like to print my plog so I can have the frequencies, fuel plan etc as well as a reference for navigating (email to hpeprint easiest) but there appears to be no way to do that from Android.  I can mail a csv or html to a printer but those formats are not seem to be supported by hp printers. On a PC with Skydemon plan I can print the plog into pdf as 2 per page in the print centre tab and mail that to the eprinter and it works really well.

I suppose I would really like the features in Skydemon plan on my Android tablet but I don't think I can install that.  Any suggestions please?
