You can fix the error Xerox Printer Offline by attempting these:
"SNMP Status Enabled" should be disabled in the Windows Printer Port.
Do not forget to turn on the machine.
An LPR.Protocol print driver for the Microsoft Windows OS can be configured, modified, or checked to see if it is.
Power off and on or reset the program as necessary.
Connect the wall/router connector and network cable after removing them from the Xerox.
