A tool that allows you to print plain-text files from a Playbook to a Wi-Fi printer. This tool has been tested with a HP OfficeJet 6500.
Note that this tool is not and will never be a full-featured proper printing tool; it is just a simple kludge.
To use the tool, you'll need to enter the IP address of the printer, paste in the text that you want to print into the box and press Print.
(P.S: If the soft keyboard does not automatically pop up for a text field, swipe from the bottom-left corner in. This gesture forces the soft keyboard to show.)
Compatibility:
The above table is not an absolute indication that the app will work/won't work with your printer. Try it first.
Known problems:
The soft keyboard does not automatically pop up. Swipe from the bottom-left of the screen towards the center to force it to display.
