Re: Escape codes for printer control

Thanks for your comment on the issues with write and escape codes.
It is possible to create escape characters with write using the syntax:
    write 1 from chr(27) '&l1O'

My problem is that I need to create the file as an ASCII text file.
For the application, an SPF file is not an option.

I also neet to ensure that the ASCII file subsequently prints in landscape using
the embeded escape charated/control sequence - i.e. The escape sequence in the
ASCII file must override the any print settings.

I belive that the problem is related to Postscript overriding any escape 
charaters
other than those recognised by Postscript.

If you have any other suggestions, I would be please to try.

Andrew,
