Hi. I have a similar problem. I am using the Printer() object to print cards
that are to be mailed out. My client is getting an HP printer with a duplex
capability. Thus I need to send the PCL command Esc&a2G to make it select
the second side of the card.
How can I mix the WritePrinter() functions with the Printer() ones? I tried
WritePrinter(Printer()->Handle, ...) but that did not work, there was no
error but nothing was printed.
If I can't mix them then how do I control where data is printed if I use the
WritePrinter() method?
