Generic Text printer with VB6

Dear Members,

I am using Windows 2000 Generic Text Printer in my VB6 application to print an invoice. The invoice size is of 120mm x 150mm. The text printer uses standard paper sizes. I want to add custom paper size to Generic Text Printer. In Windows98 I can add custom paper size to the text printer but how to do this for Windows2000. Please help me in this regard. Your earliest help in this regard will be highly appreciated.

Thanking you.
With Best Regards,
Suhaas
