I found myself using the StackPrinter application fairly often, so I wondered if it should be included on all sites. A tiny grey "print" button per question would be enough, and would quickly prompt the user to save the printed PDF.
If you are using a cool browser like Chrome or Firefox, you could use StackPrinter greasemonkey script.
This script adds a Tiny grey "print" button per question as requested.
If you are unlucky and your browser of choice is not Chrome or Firefox, you could use the bookmarklet (available on StackPrinter homepage).
Regarding the Trilogy request, thank you for that proposal but it's hardly feasible for two main reasons:
- StackPrinter is using StackExchange API that has a 10.000 calls per-day limit shared among all the apps that currently are hosted on GAE.
- StackPrinter is running on GAE without billing (limited resources)
Anyway, It will be cool to try :P
