Looking at the files, "test.ps" appears to have had some crap shoved onto the 
beginning -- possibly by the client software, who knows?

Try arranging it so that your Windows-generated PostScript files get piped 
through this little Perl script -- it's a simple filter that strips off 
anything before a line beginning with a percent sign.  Every 
application-generated PostScript file should start with a comment such 
as "%!PS-Adobe-3.0", which indicates the PostScript level to which the file 
conforms.  No harm will be done to files without any extraneous bytes on the 
beginning.

#!/usr/bin/perl -w
my $seen_percent = 0;
while ($_ = <>) {
    $seen_percent |= /^\s*%/;
    print if $seen_percent;
};
exit;
