I don’t think this is unique to my setup because I had this same problem at work with a different printer. The issue is Win7, drivers and HP laser printers. The printer shows as offline and because there is no way to tell Windows it is online so it is impossible to print. Yes I’ve tried the troubleshooter and that is worthless. Ultimately the solution is to completely re-install the printer (and yes I have updated the driver off the HP site). BUT in a while the printer shows offline again and I can’t convince Win7 that it really is online.
So why is it doing this and is there any solution to the problem?
Is it a wireless printer? Every so often my computer and printer end up connected to different networks, i.e. one to the guest network and the other to the home network making the printer appear offline.
This is a good question. I have a wireless HP printer, and it goes offline all the time. I have to go and unplug the printer and then plug it back in for it to work. Sometimes that doesn’t work, and I have to delete the printer from my computer and then re-add it. I’m sure it has something to do with DHCP, but I’m too lazy to fix it.
Can try :-
Control Panel
Devices & Printers
Right click on the printer and select Printer Properties
Select the Ports tab
Highlight the port that has a tick in it
Click Configure Port
Untick box that says SNMP Status Enabled
This sort of thing commonly occurs when a printer is added by IP address, but the print server is configured via DHCP and the DHCP-assigned IP address changes. The easiest solution is to assign a static reservation to the print server on the router and update the computer to use the new IP address, which will now stay consistent.
Maybe in your part of the universe, not in mine. My wireless printer has been on a static IP since day one. My Win10 desktop has issues finding it, especially after the printer goes into energy saver mode. It would be hardwired except for needing it from my daughter’s laptop. Every 4-6 weeks or so I go round and round with reboots and drivers and address changes to print something. And the hurrier I am, the more likely it is to mess up.
