It is seen that network printers installed in Windows 7 shows as offline, even though some of the other devices in the network can access the printer. The reason for this printer offline issue is related to Simple Network Management Protocol (SNMP) status being enabled. SNMP monitors and gets information from the network devices such as routers, printers, servers, etc., to find out if a device has any problem.
Most of the network devices has SNMP support, and responds to queries made over that with the pertinent information related to the query. However, not all network devices have this particular protocol used to communicate and establish connections as well. If your printer does not implement SNMP, but other users send a printing query over that protocol, the network printer’s status will show up as offline.
There is an easy network printer offline fix or a workaround for that in Windows 7. In layman terms, it involves with disabling the protocol in order to bypass it and fix the status of network printer. Follow the below steps for the printer offline fix.
However, in case you do not find the option, the printer must have been installed in Windows 7 with a setup file and not over a TCP/IP Port. Unless you have shared it from a server system, follow the below steps in each network computers to add the printer over the said port in each and every one of them.
