The physical print devices are associated with the "Port" objects, not the
"Printer" objects. If you add a check mark to the Enable printer Pooling on
the Ports tab of the "Printer"'s Properties, you can add a second "port" and
thus physical print device (physical printer) to the same "Printer" object.
It's not something I've actually experimented with, but try this:
1. pause the Printer
2. in the Ports tab, add a check mark to the Enable printer pooling check
mark
3. add a check mark to the Port that is associated with the other physical
printer device; click Apply
4. remove the check mark from the Port that is associated with the original
physical printer device
5. remove the check mark from Enable printer pooling; click Apply
6. remove the Pause Printer check mark
For this to work, both physical printers would need to be the same make and
model, or at least "compatible" in the sense of understanding the same
printer language becuase the spool files typically contain instructions etc.
that are specific to the printer language. For example, if the first
printer is an HP LaserJet printer and the second one is also an HP LaserJet
printer of the same vintage or later, this technique may work. But, if one
is an HP LaserJet printer and the other is and HP Deskjet printer, you will
most likely get garbage printed.
