Canon LBP7010C communication error

Ubuntu 20.04. Driver capt-2.7xUK installed. "Captstatusui -P LBP7010C" output is Communication Error. After installation the printer was working, but after samba installation it does not work. Is samba causing this or is it just a coincidence. The printer was working with Ubuntu 16.04. Installed everything again and now the printer is working. I do not know what caused the problem after the first installation.
