everyone!
I had set up a printer (HP 4500) as a network printer. It is connected via USB to the router (Asus RT-N16). It seems like the router's EZ sharing doesn't work with the HP. So, per Asus's instructions, I set up a TCP/IP connection using LPR protocol with the queue name "LPRServer". On my computer (Win10) it didn't work at first. Though after unplugging the power of the printer and rebooting my computer, it started to work fine. Everyone else's computers (all Win7) worked the first time. It has worked for 2-3 days.
This morning, people were still able to print (and I, myself, printed some things last night). Now, none of us are able to print, even though the printer shows up as ready on everyone's computers. The router shows the printer as "enabled". When we try to print, the printer's status window on our desktops says "printing" for several seconds until it says that there was an error.
I've looked for an answer. Some problems looked similar and were solved by unchecking the SNMP setting, though mine was already unchecked. I've also tried switching to RAW. Also no go.
Thanks for any help.
