At our church we have a small network. It consists of a Verizon FiOS router, several Open-Mesh OM2P-HS wireless units that relay the signal to various locations around the church. One of these OM2P-HS units has a NetGear GS108 plugged into it. Into this GS108 is plugged two printers (Dell 2355dn and 2150cn) and a Cisco SPA504G phone. There is one other permanently connected workstation in another room and then a number of roaming units (laptops).
On occasion when one goes to print to the printers they show as "offline." Rebooting the printers doesn't fix the problem. Sometimes it is across all computers, sometimes it is on just one computer - right now my laptop can't print but the workstation in the office can.
From my laptop I can ping and visit the web management interface for the printers, but when I have Windows Troubleshooting try to figure out the problem it reports, "Printer is turned off. The printer needs to be turned on in order to print."
I also tried rebooting my laptop, but it still cannot print to the devices and sees them as offline.
Any ideas on why this occurs and how to fix it?
