changing paper size has no effect

[David Andrews]

Hi to all

I am trying to setup a epson lq-590 dot matrix printer on ubuntu 8.1
i have managed to install the printer and i am able to print a test page

the problem is, i want to do continuous printing for invoices, but there is no paper size matching my preprinted invoices

if i change it to the closest one on the printer settings it has no effect
the paper stil moves up to a4 size

i have changed the paper size in /etc/papersize to another size but then the printer does not print

Anny help would be appreciated
