PrtService provides the following services:

"

Enable Driver.  Enables the driver and installs the default error handler.

wOpt should be set to PRT_ENABLE (0x0001)
lParam1 should be set to 0
lParam2 should be set to 0

"

Disable Driver.  Disables the driver.

wOpt should be set to PRT_DISABLE (0x0002)
lParam1 should be set to 0
lParam2 should be set to 0

"

Query Driver for support of an option.  Determines whether the driver supĆ

ports a particular feature.

wOpt should be set to PRT_GETSUPPORT (0x0003)
lParam1 should be set to the value of the option you want to check.
lParam2 should be set to 0

"

Install/Remove External Error handler.  Installs or removes the applicaĆ

tions error handler.

wOpt should be PRT_SETPROC (0x0010)
lParam1 should be a far pointer to your error handling procedure.  A valĆ

lParam2 should be set to 0

"

Flush Driver.  Flushes all the data buffers so that everything sent to the

printer actually gets printed.

wOpt should be set to PRT_FLUSH (0x0020)
lParam1 should be set to 0
lParam2 should be set to 0

As pointed out in the topic Default ErrorĆHandling Mode," the IrDA printer

driver can provide the error handler and thereby translate all printerĆrelated erĆ

rors into a Cancel or Retry option for any application.
However, if the application provides the error handler, custom messages can be

attached to the error returns.  As shown in this table, seven different numbered

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