Hello Ian,
First of all you have to make sure your printer allow to print in customised paper sizes. Not all printers allow this! In the QSL Cards folder you have many samples, all of them normally based to print on a A4 paper. However try this:
QSL 9x14 Example 2.rpt
This is based to print on Custom Paper Size of 5.5" x 2.95" . If this is working to you, edit the "QSL-Card for more than 1 QSO", enter report Setup and adapt the Paper Size to fit your custom paper. You will probably have to play a little bit with margins and do some print outs before you get your report working.
I suggest you to read this thread also:
