[newbie] prints lightly

I've used test pages in KDE printtool and each test printed correctly
with an Epson 24 pin. However, the lines print too lightly and are
barely readable. Read the Help items. 
Set the print head to the closet paper level. Also put in a new ribbon.
That didn't help. 
What do you suggest trying?
Thank for your help.
