is there anyway to set the Length of the Paper Size to be Dynamic when printing.

Question

lm using a Epson u220 printer and need to print Continues paper, when ever I generate invoice Report.

Now I have a hard time on how to set my Paper Size to Width = 5 and the Length to be a dynamic.

Meaning If the Data of the Invoice Report can fill up a Lenght 25 inches then the Custom paper size will be
5 X 25. and If the Data of the Invoice Report can fill up only to the length of 10 inches then the Custom paper size will be
5 X 10.

So is there anyway possible to set the Length of the Paper Size to be Dynamic.

FYI,
i am using crystal report's
report.PrintToPrinter(1, false, 0, 3); for print the document.
