And I replied:

Install any of the PostScript drivers on your system (if you already do not
have one installed - Linotronic is OK), print to file (extension .PS), use
CorelDraw, draw a white filled restangle which coincides your board outline
and send it to back, select all, from Effects menu select Invert, and print
again to file in .PS format.

Your design is now ready. This is the way that I usually do all
preparations for the files that I use for singlesided boards when I want to
add some things that 99se is not capable of.
