custom paper size 15X12 using windows xp os

You can create custom page size by clicking 'File->Server Properties' in the Printers and Faxes section. click 'Create a new New form' in the server properties screen, set the page size and save the form.

This paper size will be listed in the printer dialog box if the printer driver supports the paper size.

In some cases, The original driver supplied by the printer manufactuar will not support the defined paper size. ie, even if your printer support 15" pages, the printer dialog will not list it if it is greater than 8.5". In that case you can use any other compatible printer drivers. I had such experiences. In my case the original driver came along with the printer didn't work. So I put Epson-fx 2180 and it worked fine. Hope this would help you.
