GetDeviceCaps() for printer drivers

NTDEV
1

OK, it must be that today is my first day at work after 2 weeks off. My
brain is clearly not functioning at 100%.

I have a monolithic printer driver and I can’t find where it implements
the driver’s side of GetDeviceCaps(). Specifically, RC_DIBTODEV and the
other RC_xxx values. I can’t even find where those flags are stored.
Can someone give me a hint? But make it pretty obvious.

Thanks,
ScottR

It’s because Windows just assumes that all raster printers support all
those flags, isn’t it? Windows doesn’t check with the driver at all.

GetDeviceCaps is implemented by GDI and the information it returns is based on the GDIINFO structure that the driver sends back to GDI from its DrvEnablePDEV call.

Yes, but these flags in particular (RC_xxx) are not part of the GDIINFO
struct as far as I can tell.
