I may have the same problem. Running Mageia 9.A Brother MFC, so new that it only just being listed by CUPS. Getting messages on USB and Wireless, "Waiting for printer to become available." The troubleshooter from Linux Mint says that the computer is not broadcasting a list to the printer. It seems to be almost a standard bug in Windows 10, which I have installed, but rarely use. Using USB, nothing would print except when rebooting. That somehow opened a "window" for a couple of seconds, allowing 2 or 3 pages to be printed.
