method, change the FlagWhenIdle property to TRUE. When all data has finished printing, the
printer becomes idle and a StatusUpdateEvent is fired to the application with the value of
PTR_SUE_IDLE.
5.1.2.2 Printer Errors and Status
A change in printer status when asynchronous data is being sent is made available to the
program by the firing of an ErrorEvent and StatusUpdateEvent. When the printer changes status
while nothing is happening, the change is told to the program by a StatusUpdateEvent only.
As an example, assume that the printer cover becomes open. Usually, when data is not being
sent to the printer and the cover is opened, a StatusUpdateEvent is fired to the application. After
the AsyncMode property is set to TRUE and a method is used to print data, if the cover is
opened while the data is being sent, the program is notified by an ErrorEvent. ErrorEvents are
fired when the error has interrupted the data that is being sent. Only StatusUpdateEvent will
fire when the error does not effect the data and the data will continue being sent as normal.
Reasons for the ErrorEvent being fired and the corresponding error names are listed below.
