Neither of my 2 HP printers will print

Since 1966, I have owned only 2 cars, and I still have both of them. The car I now drive daily will be 32 years old in March. It works fine; so why update it to a newer model? I feel the same way about software. As they say, "If it ain't broke, don't fix it!" Ubuntu 16.04 has worked perfectly for me until now. So now I'll update it.

Yeah, no point in trying to get support for a release that hasn't been updated for 3+years

The site <https://developers.hp.com/hp-linux-imaging-and-printing/howtos/install#howtocheck1> tells me that in order to discover if HPLIP is installed on my computer, I should run in a terminal this command: dpkg -l hplip
I ran that command, and the terminal replied with this info:

It appears to me that HPLIP is not installed. Since my version of Ubuntu is almost 6 years old, I'm going to install Ubuntu's latest LTS offering. Thanks though for your willingness to help.

If you are missing a file - which would be odd IMO - you might reinstall cups. @here that file exists.

What about HPLIP? Do you have it installed?

I have 2 HP printers (MFP M277dw and LaserJet 1022) and a Dell laptop running Ubuntu 16.04. I bought the laptop in March of 2017; so in 3 months, it will be 6 years old. I have had no problem at all until now. The problem seems to be with the CUPS. When I try to print using the M277dw, it doesn’t print, and Ubuntu’s system settings for printers tells me that the /usr/lib/cups/filter/hpps file is missing, and it is. When I try the other printer (the LaserJet 1022), the printer diagnostics tell me it’s not plugged in or turned on—but it is, and it will print a test page. I know zero about CUPS. Any advice you can offer me to solve this problem will be greatly appreciated.
