I have a client with a Xerox 560 and everything is printing fine, but they tried to labels one day. As they had done in the past, they selected labels as the media type on the printer when they inserted the paper in tray 5 and they slected labels for the media type and tray 5 in the driver as well. The file would spool and then not drop from the que once it said printing. I printed the same file and turned the media types to plain even though I was printing on labels and it printed fine. Any idea of why this might happen? I have a 550 and never had this issue and my client has been able to print labels with selecting the label media in the past.
