There are a few reasons why a file might now show up in your release queue even though it looks like it printed.
1) Verify your network connection, especially if you're printing wirelessly
2) Is there still a printer icon in your dock? If so, click on it and make sure there are no files listed there. If files are still present it means they are still spooling to the printer. Do not close or log out of your computer until all files vanish from the queue on your computer.
3) Once you've verified that it looks like your file actually sent from your computer and you're still not seeing it in your release queue, it could be one of two things:
a)Does the home directory on your laptop differ from your MCAD Login username (i.e., "joesmith" instead of "jsmith?")
i)If so, you must install and run the _CLIENT REQUIRED_ version of the MCAD Printer Utility that includes the_PaperCut client. See THIS article for help and look at Section 2.
b)You may have sent a document set to a size the printer does not support. The SB-BW-Letter and SB-BW-11x17 printers are set up to only accept files of those sizes. You will get an automated warning from the PaperCut server.
