Need pointers for color graphics screen dump

I have looked around, it doesn't seem like this particular wheel has
been invented yet. Graphics.com in MSDOS 4.01 doesn't do it, neither
does User Friendly's PRTSC, though I can get b/w dumps in some
combinations.

Specifically, I need to dump (mostly EGA) colour screens to a Brother
4018 printer, in colour, preferably in Epson (JQ compatible?) mode.
The video board is an Orchid Prodesigner Plus (512K).

I intend to do this as a TSR in Turbo C 2.0, I reckon I'm competant
enough to handle that, and I've written dot matrix printer drivers
before, so no problems there either, but I've never had cause to
investigate the mechanics of graphics cards on a PC before, and don't
want to go into it *in depth* right now.

As a last resort, I might consider using GRAPHICS.COM /COLOR8 and
redirecting PRN to a file, (or piping) and filtering it, but that's 
a bit heavy on the disk, not to mention messy, though it's useful for
reprinting, so a suggestion for an existing TSR to do the redirection
would also be welcomed.

All I really need is a brief explanation of how to access the data,
and/or some suitable fragments of source.
Best of all would be the source to a similar programme for a different
printer - I'd guess that might exist in the PD somewhere.

PLEASE reply by e-mail, I really can't cope with the traffic in the
.pc groups these days. If there's sufficient interest, I'll post a
summary/sources later.

Thanks for any and all help,
