Hi,
Most of the issues with non printing jobs and „Offline” messages are from driver settings.
First check to see if there is no job in the print queue (delete any job if exist). Check the port to be on TCP/IP and not WSD. MS convert the port to WSD. If it is so, click right on the print driver and click on „Printer Properties”, click on „Ports” tab, click on „Add port”, select „Standard TCP/IP port” , click on „New port” and set an IP and in the next window click „Finish”.
After that click again on ''Ports'' tab click on "Configure port" and change from RAW to LPR, at the Queue name write "lp" and be sure to unchecked "LPR Byte Counting Enable" and "SNMP Status Enabled".
