*ColorMode entry in the GPD

NTDEV
1

Hi All,
I am working on an Unidriver based printer driver for Win2K. I have the
following *ColorMode entries in my GPD:
*option: Mono -> for 1BPP
*option: 24Bpp-> for 24BPP color rendering.
I have a requirement wherein I want to put these entries within a switch
case. For example, something like this:

*Feature: ColorMode
{
*switch:condition
{
*case: condition1
{
*% Have both the color mode options here
}
*case: condition2
{
*% Have only 1Bpp option here
}
}
}

But the minidev.exe tool gives me an error when I check this GPD. It gives
me an error telling that this feature(DevBPP, DevNumPlanes) cannot be
within a SWITHC_CASE_STATEMENT.
Is there any other way of achieving the same result?
Thanks in advance

The HP Color Laserjet sample in the DDK does what you are trying to do.
It has the following two sections. Refer to hpclj.gpd in the DDK for
further details.

*switch: ColorMode
{
*case: Mono

Resolution.Option1, PrintQuality.Option3)

Resolution.Option2, PrintQuality.Option2)

}
