Here is my scenario:
I have two computers, one a windows 8.1 machine that hosts the HP LaserJet 4100 printer. It has a LPT port, which is used by the printer. I have printed pages on the printer successfully from that machine. The other machine is a windows 10 machine. I have been trying to share the printer on the network via the windows 8.1 machine and add it to the windows 10 machine. I have followed several online tutorials that give me instructions on how to do this. Both computers are connected to the building wired network.
I have followed this link
And this link
And multiple others as well.
After setting up the printer on the network, I go to the Windows 10 machine and click "Add new printer". As seen from the links above, I have enabled printer and file sharing and disabled usernames and passwords. Both machines are in the default workgroup "WORKGROUP". I have attempted to add the printer by typing in the IP address when selecting the option to add the printer via the IP and I have also tried adding the printer by typing in "\{computername}{printername}, however when I do this for the first time, the windows 10 machine asks for a username and password. The Windows 8.1 machine has no password, just a username. This is odd, because I have disabled the ability to use usernames and passwords when adding this printer. I have put in the {domainname}{username} and a blank password, since there is no password on the machine, and I have received an error that says "Access Denied". I have looked into the permissions given to the printer when looking at the printer preferences and when All Users or Everyone is selected, the permissions to print documents and manage the queue have been given to all users.
I have tried to add the printer when it was configured to manage the queue on the client machine and when it was configured to manage the queue on the host computer. Neither configuration has worked.
I´ve continued to try this same process over and over again, even on another machine on the network, and yet I am still unable to add the printer. Help is greatly appreciated!
