Charging appropriately for print credits
I was wondering if anyone can give me advice on how the charging / allocation of print credits is managed within their schools...
Basically we have a number of teaching staff who works for several different depts - e.g. one is timetabled to 10 periods music, but the rest science etc. I've been given the ok to remove an allowance from each dept's budget to cover printing costs, but here's the issue - what do I do about the teachers who work between different depts?
Ideally I plan to give each HOD a set allowance, and subject teachers another allowance, then if they need topped up it must go through the HOD.
Unfortunately the managed service provider here only has a single figure for print credit allocation. On our internal network I am able to allocate it a bit flexibly, so they choose their department cost centre, but unfortunately not on the system the teaching staff use.
Thanks for any help / ideas!
