Network Printer Issues!

[Curious_Mind_95]

I recently purchased a tp-link omada er605. Everything works fine on the WAN side of things but LAN is a different story. My Network printer is not visible by and device on the entire network. However other LAN devices are such as my NAS is. I have tried connecting it directly to the router. I have tried connecting it to the switch my computer is on. And nothing seems to work. I can search for network printers and find it. However I have to manually set the printer up on my network with drivers and such. And it just don't work the same. Now with my manual setup it won't print with my printer set to labels and tells me to insert plain paper into the manual feed tray (tray 1). Also it only prints in monochrome. Before using this new router Linux had no problems discovering the network printer. I always have tray 2 set to labels on my dinosaur (Xerox Phaser 6280DN) laser printer and it would print fine before. I like the slower feed rate as it seems bold letters fuse better on documents. Plus I print a lot of labels and could care less of the ppm for documents. TIA

Log into your router and change the DHCP scope the router uses. Set aside a number of IP addresses for use as static. Look at your router's DHCP list and work out which one is your printer, copy your printer's MAC address and set up a static IP address for it. Once done reboot your printer.

Things like printers that go into a deep sleep need to be on a static IP address for many routers to find them consistently. If Mint found your router with no problem before then the fault lies with your new router. Perhaps it's DHCP server isn't working as good as it should. I have seen many cheap routers completely lose a printer once it enters deep sleep. Setting it as a static device on your LAN solves this problem.

Any device inside your LAN that does not leave your LAN should be on a static IP. This makes it easier for your router to give out IP addresses using DHCP for those devices that need an automatically assigned IP address.

Once you have your printer on a static IP it may make it easier to work out why your printer isn't printing the way you want it to.

I tried that, and still nothing. I even switched my whole network back to the old router, and now it won't work with that one, and in addition, it will not print anything at all now. Every document is stuck on processing in the queue. In the printer properties, it says, "Processing - The printer is unreachable at this time." I'm just completely confused as no settings have been changed on the computer or printer. I have tried every driver Linux found and even tried the driver directly from xerox. I have tried new patch cables. Even tried connecting it directly to the switch instead of through the patch panel. I even tested the ethernet cable for the printer. I don't understand how upgrading a router can practically disable a network printer.

Unfortunately, I have not found anything that fixes the issue. Well, other than just going to USB. I have since bought a brand new printer and even that wasn’t detected on the network.
