I grabbed the file and tried it just a few minutes ago.  I don't get as
many errors as you did.  And it produces obviously buggy, but recognizable
output.  You probably ran it through an obsolete unprinter.

You mean you didn't intentially post kiddie porn on your website?  ;)

Actually it appears to be a rather low resolution family photo.

I'm not quite sure what to make of the remaining errors.  The most serious
error you saw was:

             Error decoding RLE data.
             Total bufsize 650, expected 624

When this is encountered, unprint decides it's beaten and just ignores the
whole rest of the file since problems reading compressed data are really
hard to recover from.  There was a bug in the RLE decompression code that
I fixed quite a while ago.  That's probably what accounted for this.
In any case, I can't reproduce that error now.

Of the less serious errors, the most interesting ones I get are:

Warning: Unknown command ESC 0x1.        Secret init string?
Warning: Unknown command ESC ( 0x52.     ESC ( R?
Warning: Unknown command ESC 0x0.        The null command?
Warning: Unknown command ESC ( 0x44.     ESC ( D?

All of these occure while parsing the header.  Once the raster data
starts coming there are no more errors.

It may be time to send another message to /dev/nu^H^H^H^H^H^H^HEpson
techincal support and see if they are willing to comment on this.
I think I'll go do that.
