The readme includes instructions on how to install, and the current bugs that are there. Besides those, sugar-emulator on fedora 11 experiences a delay of +1 min to load the activity. This is because of the enumerate printers loop. I am playing with the gtk+2.0-unix-print api lately, should come up with a solution soon. And please test the Sugar-Print-Moodle-Print XS integration, we never managed to test the code. Add a student to the site root module like this: System context: Site Administration > Users > Permissions > Assign system roles (this context is named "site" in Moodle 1.7) so you can test :) Oh and ReadMe's are incomplete. Also to adding to the moodle print module, it doesnt act as an activity. That is, you can't add instances of more than one , and every instance is added to the root module (site) itself.
