Hello,
I have recently installed the CUPS printing server on my Raspberry Pi. I had installed it fine and everything would work and print OK - the only problem was that every time I went to go to administrate the printer I added, it would come up with a 'Forbidden' message. I just ignored that as I didn't think I would need to administrate it as I had set up the settings when I installed the printer.
Now today, I was trying to print something and the server got 'stuck' meaning it would not print anything and was showing as 'paused' on my PC (running Windows 10). I had tried a lot of configuration options, and searched on Google - unfortunately nothing worked for me. Eventually I decided to just reset my Pi and I re-installed Raspbian on to it.
I've reinstalled CUPS again but I am still getting the same forbidden message (I only get this when I go to https://<ip-address>:631/printers/<printer>, which is the same issue as before):
I want to be able to fix this error but I am not sure how - so I came to this forum. Any help is appreciated.
Here is my cupsd.conf:
