Cheque Printing issue in Epson(Dot Matrix Printer)

Hi Friends,

I am using standard Cheque_US,My cheque is of size 9 inch(length),3.7 height.I have designed custom size in ssrs.

But if I print in dotmatrix printer.cheque is printing on pre-printed paper,but skip 2 more leafe.As I can see at printer and devices,Printing preference for Epson printer is Letter.

How can I change Printing Preference to 9*3.7,any idea??

How can I print a cheque from Epson Printer.
