I just submitted the following as a "bug" (feature request) for the
gs package.  Assuming these stc740 files are added to the gs package
in the future please add a set of StylusColor-740@NNNdpi filters in
/etc/magicfilter.  It is an easy addition.  Just copy the -800 one and
change all references to stc800 to stc740.

Subject: gs: stc740*.upp drivers not included
Package: gs
Version: N/A
Severity: normal

Here are some std740*.upp files needed for ghostscript to support Epson
Stylus Color 740 printers [dug up a while ago after some web searching;
they work well for me].  Please include these with a future release of
ghostscript in woody.  They belong in /usr/lib/ghostscript/5.50 with
the other upp files.

thanks,
Greg
