Hello there, I had a similar problem with the reader. Try this:
File ---> Print
Then click on properties in the top right of the window.
In the "Printer Command" bit it says
Code:
/usr/bin/lpr -P printer_name
(This command
should be fine on cups but for some reason it doesn't work here) So change it to use good old lp.
Code:
/usr/bin/lp -d printer_name
It solved it for me, hope it works for you.
