        You've just described the layout of the 320-mode super-hires screen.
It short, you've _already_ got an uncompressed screen image.  The only
hangup I forsee is the filetype; other software (such as DeluxPaint or your
word processor) will not recognize it if its filetype is BIN.  According to
_Exploring the Apple IIGS_ by Gary Little, you want filetype $08.  There
are a number of utilities that can change filetype; I know ProBlock (which
recently appeared in comp.binaries.apple2) can do this.  I think that if you
simply change the filetype to $08, you'll be all set; you can then view it,
print it, etc. from any decent graphics editor such as DeluxPaint.
