I recently switched my Lenovo thinkpad X1 yoga 4th gen to Ubuntu 24. I use this computer for work and have been unable to print to our main office printer since making the switch. We have two printers at the office and I am able to print to the Canon MF 1643i II in our med office, but not the Canon IR AdvanceDX C3835i. I can see both printers in my printers list in settings, but I am only able to print from the Canon MF.
I have installed cups and checked that it is running which it is. I have pulled up the cups gui at localhost:361 and attempted to login using my name and password for my machine, but it did not work. Now when I try, the admin page does not ask me for credentials and simply says unauthorized. I am hoping for help in getting back access to cups admin page or a workaround to add the printer without the need for the gui. I am most definitely a linux newb in many ways, so please know that I will need some basic hand holding type of guidance. Thank you all in advance!
