As pointed out in the Default ErrorĆHandling Mode paragraph, on page 3Ć39, the

IrDA printer driver can provide the error handler and thereby translate all

printerĆrelated errors into a Cancel or Retry option for any application.
However, if the application provides the error handler, you can attach your own

messages to the error returns.  As shown in the following table, seven different

numbered returns are made available by the driver as generic hook points for

messages.
