Several attempts to install the Epson L365 ink tank printer on the Ubuntu 20.04 LTS computer were futile as the L series printers never showed up on the list of printers in Settings -> Printers and Add printer. Even though Epson was available for selection, it only showed the dot matrix printers in the list of printers that can be installed.
To overcome above issue and list the Epson L360 series ink tank printer driver on Ubuntu, open a terminal window and enter the following command:
$ sudo apt-get install printer-driver-escpr <enter>
The above package printer-driver-escpr is a necessity as even after downloading the Epson L365 printer driver from the epson site at http://download.ebz.epson.net/dsc/search/01/search/searchModule where Epson has published the Linux drivers for download, the Epson printer list does not show the L series ink tank printers.
Installing printer-driver-escpr package therefore, solves the problem. When you select Settings -> Printers -> Add and choose Epson from the list, you will now see the full list of the Epson Ink tank L series printers.
