Print and Paused Queues

We are currently printing to 3 queues to 1 printer DP-Greenbar, DP- Statements, DP – Invoices

We want an operator (and others) to first pause the active queue, then unpause the desired queue. By clicking on Printer properties and then pausing, is error prone, as one click, and the printer will start printing with the wrong form, or the operator forgets to pause one of the other queues and a user will print greenbar info on invoices.

Is there a command line or other third party utility that I can use to pause – then unpause a Print Queue ?

Thanks
