When trying to release a print job remotely, you will need to login to the Papercut website to do so.
On the menu on the left side you will see "Jobs Pending Release
In that menu, you will see the print job that you have waiting to be released.
You will see the information regarding the print job and the options to print or cancel the print job. When you select "print" you should now see a list of all the printers tied to the print queue you release to.
*The example picture is of Mansfield's MU Printing queue, but yours should look similar if off the Mansfield campus.
When you click on the printer that you want to release the print job to, it will release the job on the appropriate printer (MFP)
