Have two printers--HP and Epson--which were both working. Was looking at a pdf in Okular, and tried to print it using the little printer icon in the panel. It showed four items in the print queue, which I can't account for, but I think I got rid of them with the options available. Would not print. Tried the other printer, same routine, won't print. Now tried printing with each printer from a text in Kate. Neither printer will print. No error message. The Epson has a scanner function, and that still works. ( I don't know why there is a printer icon in the panel, if it's not going to print.) Here is an nmap report on the LaserJet: doug@linux1:~> nmap --reason 192.168.1.29 Starting Nmap 7.80 ( https://nmap.org ) at 2021-01-04 15:55 EST Nmap scan report for 192.168.1.29 Host is up, received syn-ack (0.0066s latency).

I don't know how to troubleshoot or fix this. Please advise. --Doug
