Changes

:for step-1, We use CUPS. The API has a nice array of functions, one of which is to get the printer's name (the cups-pdf virtual printer).( Since we know the name is CUPS-PDF, we can check it) and print our file as a PDF in the journal. For the sake of our python convenience we will be using a python wrapper to cups, pycups. The print objects will have metadata attached to them through the sugar datastore API.

:For the second part of it when ever the print page url is found, we make browse communicate with the moodle print queue through xmlrpc get the details, and upload to that many slots (as the number of slots will also be dependent on the print queue) This would essentially mean a rainbow hack so that browse can communicate with journal without a dialog. The execution part of this will take place as the And once the pdf is read, it is destroyed.

The execution part of this will take place dynamically as soon as the user requests the print page.

:for step-2, We will be using the interface already created, but for the teacher we will issue global access privileges enabling him/her to access all the sent requests, and the approve button will initiate shell commands to send the particular file to a network printer through CUPS installed on the server.This can again be achieved through hacking into moodle and understanding how notifications are sent to the students from teacher. The notifications would be relating to whether the teacher has approved or disapproved the print.  case a, we would just make

:for step-3, no new code is required, just a slight modification of the cp activity to select the type of printing. A few more dependencies, Which wont exceed 17mb. We will be including print directly (usb), as an option under the item's right click menu too.
