Welcome to TSF,
The error code is usually a sign of a firewall issue. Do you have any Security or Firewall software installed from the problematic computer and also to the computer that you're trying to connect to where the printer is connected to?
Another option, you might want to check if your router has a USB port bec you may plug in your printer and no printer sharing is needed using a Workgroup or Homegroup and it's hassle free this way.
