I have a Samsung SCX-3405FW Multifunction Laser Printer connected wirelessly to a PC with Ubuntu 20.04 installed and system had automatically installed a driver, but after printing a document I always get an error at the next boot up of the PC. So, I downloaded the latest Ubuntu driver from HP and successfully installed same using a procedure I found online. Although the system indicated it installed successfully, I continue to get the error after printing a document, so, I do not think that the driver was actually updated. Please advise. Thanks.
