See previous posting.

Sorry, I should have added more to that statement.  The %! by itself is not
part of EPSF ot EPSI.

<From Encapsulated PostScript File Format--Version 3.0, section 2.1:
<
<	    The two required DSC Header comments are:
<		    %!PS-Adobe-3.0 EPSF-3.0
<		    %%BoundingBox: llx lly urx ury

But, as you point out here, the %! with the rest of the line is.  I should
have said that it takes more than just %! for these formats.  I knew that,
but I just didn't say that.

<TranScript software makes the decision to print a PostScript lacking

<TranScript DOES NOT switch the printer to Diablo emulation mode.

I don't have the source on this system, the other person has TranScript
source.  So, he missed how it worked and I was miss-informed.  I guess that
I should have read the TranScript(8) man page, as it does tell all.

I should have known better :-(
