custom form with generic text driver

Using the ct-310 driver  itself is very slow when using the remote desktop services in windows 2008 r2 (25 seconds to print)

using the generic text driver it prints way faster (1-2 seconds) but the format is off.

I have created an custom form, however it is not listed in the paper size.

the custom form is 80x3276mm.

I am not sure why it's not listed at the paper size setting (found something that the printer must be able to handle the paper ??)

Else I want to use the printer commands options to set the paper size in there.(80x3276mm.)

any suggestions ?

regards
