Try printing on the computer. Ok if you can! No, keep looking down! ! !
2. Check whether the service related to your printing service has been started. Such as: server sharing service, etc. Did you use the optimization software?
Some printing services have been closed! Such as: print spooler printing service in 360!
3. Check whether the computer and local host connected to the printer have set the printer to suspend or offline!
4. Are Computer A and Computer C on the same network segment? Is there a small route or something on one of them? If it's different,
Is there no special treatment for two computers accessing each other between network segments? If it is the same network segment, ping can try.
Pass the ball ! ! When installing the printer, see if you can connect to sharing and browsing.
If the complaint procedure still doesn't work, I suggest you reinstall your printer driver on the computer you want to connect! It's even possible
Reinstall the system!
