Sometimes the Print Queue will be halted by an error, and the Print Spooler needs to be cleared.
This isn't a CabMaster or EzyNest/Enroute issue, it's a Windows / Printer issue.
To clear the spool without restarting the computer:
Hold down the Windows Key and press “R” to bring up the Run dialog. (type run into the start menu)

Type services.msc, then press “Enter“.

Find the “Print Spooler” service in the list. Right-click it, then select “Stop“.

Leave the Services window open. Hold down the Windows Key and press “R” to bring up the Rundialog.

Type %systemroot%\System32\spool\printers\, then press “Enter“.

Select all of the files by holding “CTRL” and pressing “A“.
Press the “Delete” key to delete all of the files.
Go back to the Services window, right-click “Print Spooler“, then select “Start“
