i have been using an LBP6030w printer on my 2018 iMac for 5 years. With the latest upgrade to MacOS 13.6, the printer would often not be found unlesss power cycled. So I deleted the LBP6030w printer in System Settings -> Printers, installed the latest printer driver UFRIILT-CARPS2LBP-v1512-00, and restarted the iMac. I then tried "Add Printer", but nothing showed up. I then tried "Add Printer" on my new M1 MacBook; worked fine.
