FWIW I use PrinterShare app on all my Android devices and print to my HP Photosmart wireless printer. The printer is on my wifi network. This arrangement works well as I can print from my phone, tablet and computers.
Interesting - I do this all the time with Docs to go and printer share combination.
The key is to use the Google docs folder on Docs to go. Once the file that needs printing is saved in Google docs folder then open Printer Share and select Google docs and select the file for printing.
This works for me for quick mobile printing. Anything more intricate I simply print from PC.
OK, how do I get the file into Google Docs from Docs to Go? When I open a email and save it, it goes to Docs to Go not to Google Docs, how do I get the file into Google Docs, is this a stand alone program or something?
3 key points:
1. You have to configure doc to go to be able to access google docs. You do this by entering your google credentials within docs to go.
2. Open the file of interest. from what you describe this probably a word or ppt document attached to email. Open the file with docs to go. Once open save the file to google docs. Use file save as and select google docs from the pop-up.
3. Open Printer Share. Select Google docs. Select the file of interest. Print the file.
Of course you must have a nearby printer available and set up within printer share. In my case it is a wifi printer on the same network as the Galaxy tab.
This method allows me to print using any Android device.
