Re: Windows printing problem

[James <jamessteward optusnet com au>]

Hi,

I've refined the code a bit.

This I can print to PDF using pdfFactory Pro, and it is displayed in the
pdfFactory Pro preview window properly, but Windows always errors out on
the actual printing.

Printing direct to the printer (HP laserjet) also causes windows to
report an error trying to print.

(The printer works fine for every other app on Windows and Ubuntu).

Draw page code below.

James.
