your printer had a driver in the gutenprint package as per
http://gimp-print.sourceforge.net/p_...d_Printers.php
use your web browser search function search term 1020 gives me an exact match
so you need to install cups and gutenprint
you need to ensure cups daemon is running
Code:
sudo /etc/init.d/cups status
# should return running if not then run
sudo /etc/init.d/cups start
then in web browser assuming its a cable or full wireless printer click on this link
http://localhost:631/admin
click on the add printer button
popup asks for username and pw....use root and its password
then page will show detected printers....pulldown and choose the
gutenprinter driver for you printer.
if you have problems tell us what you did and take a screenshot of where you are not quite succeeding please
