Custom scrip to print tickets on creation

Running RT-3.6.1 on Debian3.1

How can I go about creating a custom scrip to print ticket on creation, the
reason behind this is that we have a remote location where there is only one
computer that is used by 5 individuals, and not all of them can use the
computer at the same time. But we have an available printer that they could
get their tickets from and go on to the their job…

Thanks in advance

P.S. Not all of the users have email accounts so we think that if they print
the ticket and leave at the point of service, as hard copy for the job
