I can see the printer, but I get “Permission denied.” I add everyone, guest, guests, set all privileges for all and always the same: “Permission denied.”
Not only home, but professional also can’t connect.
\\Win10MachineName(with valid credentials)
If you have problem with “Printer Processor not found or invalid” - change driver; don’t use the existing driver.
There can be problems with credentials - if you are not logged in to
\\Win10MachineName after reboot - the port is unavailable until you log in.
This helped me. I didn´t try badongero's solution (but looks good when having "only driver files" without setup)
My actual solution: First install printer locally. This involves running appropriate OS compatible printer drivers setup for USB connection (connecting for a while the printer).
Next make shure a connection to the server is open. Verify typing > NET USE in a CMD Window and if neccessary, just open in File explorer \\HostPC -write it in the direction box-, and credentials will be prompted.
Finally make the new local Port creation / assignment.
For badongero's way: First make shure an open connection to the HostPC exists. Then try the AddPrinter -> Local printer -> NewPrinterPort ...
Note: In some scenarios on rebooting PC, will not restore connection. Put a shortcut to File Explorer opening the Host machine in ..programs START folder to reset the connection everytime.
