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.

After an error occurs, more detailed information about the error can be obtained from the ErrorLevel,
ErrorStation, and ErrorString properties.
