I have Ubuntu 18.04.1 LTS installed on my computer. I try to install printers HP Laser Jet 1020 and Canon MF 3010 and Lexmark x1180 all in one with scanner.
I do everything correct and installation of HP 1020 and Canon MF 3010 are all right. When I command to print something I notice that printer tray work but nothing is printing. When I command to print test page it answer that print page is printing, but nothing is coming out of printer. Lexmark x1180 doesn't work because I can't find any properly installation. Can you explain it to me?
