Papercut

kidpressingbuttons · March 27, 2014

Hello All,

We are currently looking into implementing Papercut in our school, it has already been set up and is ready to go!!

However we want to be able to add a daily generated password for the morning and afternoon which the staff and students would have to enter to be able to print, have had a look into this but just wanted to know if anyone else has had any experience with this?

Yes, you can do this with department pin codes that reset twice a day. I have a script somewhere for my student shard acounts that dose that. I'll see if I can dig it out.

That would be extremely helpful thank you!

ICTonto · March 27, 2014

You can create a shared account with a PIN code if that is what you are asking?

kidpressingbuttons · March 28, 2014

Mostly along the lines that MicroDigitUK was saying. But I'm open to any other suggestions if you have any?

ICTonto · March 28, 2014

MicroDigitUK is spot on, there is a scripting recipe for this called "Require Approval Code", however i don't know how to cycle through PIN codes automatically, might be worth asking papercut support they are very helpful.

Big_Ted · March 28, 2014

Sounds like something that would require some upkeep. people asking for passwords and then new passwords being created. If you are going to tell them the password anyway what is the point of ever changing it

In my experience you would be better off using 1 of the many other features in papercut to keep an eye and restrict printing.

OK, this script is to reset shared accounts. All of the shared account names must start with "STUDENT" or the script will ignore them. e.g. I have student shared accounts called "STUDENT Art", "STUDENT D and T" and "STUDENT ICT" ...

This BAT/CMD script is then just scheduled to run at the times you wish to reset the pin codes for the shared accounts.

You, will need to set the SERVER_COMMAND to the correct path. This must be the shortened abbreviation old DOS style path e.g. "c:\Progra~1" and not "C:\Program Files". Had issues running the script with full path.

Part 2: Ok once you have all of your student shared account codes reset you will need to easily view them. This script will output all of the "STUDENT" shared accounts to a JASON formatted file. This can then be read by a web based application and displayed on a staff intranet or VLE page.

The script also uses "Iconv" to convert character encoding as most systems read JASON in UTF-8 format. Iconv can be downloaded from:

http://gnuwin32.sourceforge.net/downlinks/libiconv-bin-zip.php

SERVER_COMMAND, JSONFILEPATH and JSONTEMPFILE should be changed to meet the setup of your server.

Part 3: The web app to display the information from your JASON file on your VLE or intranet to the staff to distribute the shared account codes.

I have published 2 options but you could re-produce this in ASP.net, SharePoint, or as a Moodle block. My 2 options given are as simple PHP page and a Frog3 widget.

Retrieving pins...

MicrodigitUK · March 28, 2014

@kidpressingbuttons a bit of background into how we use shard accounts and scripts in my school.

We use the PaperCut with shared accounts and don’t give anyone credit on their personal accounts.

We use the shared accounts as department accounts, similar to how most schools do on their photocopiers. Each department has a pin code and they enter that code in the popup window to release there prints.

Also for students/pupils printing each department has a second student pin code. The only difference being that the student codes change twice a day. (Done with a simple script and scheduled task) This is to stop students memorizing pin codes and printing to the incorrect department.

All department pin codes are published on intranet/VLE for staff access only, Staff then only give out the code to classes when they want students/pupils to print. At the end of each month the total of Staff and Student shared accounts are charged back to the departments covering toner and paper. (Departments are allocated in budgets enough funds to cover their printing charges.)
