Hi,
I'm trying to select a printer in the system printers collection. I'm able
to do this.

However, if the printer is a network printer and happens that this printer
is not on or not ready, I won't be able to know and I try to print a
document I will get an error.

Is there anyway that I can check the status for the printer that the user
select is ready or not?

Regards
Vanessa
