.1	Print limit / print account
<p>Your print administrator probably did configure limits how many pages
your are allowed to print on a group of printers.
The limit my be zero (denying access) or unlimit to allow unrestricted
access. A numeric value configures a number of pages.<br>
A limit is valid for a given period of time, i.e. semester, trimester
or school year.
</p>
<p>In addition to the limit (established by faculty leader,
school director...) you can have a personal print account,
i.e. if you have paid for it. This print account remains intact
when the teaching period changes.
</p>
<p>Pages from the limit are used if you did not yet reach the limit.
The pages used within the limit are counted from 0 upwards.
</p>
<p>After reaching the limit you can only print if there is a positive
number of pages in your personal print account (if any). The personal
print account is decreasing while printing.
