• Monitoring while printing

Status monitoring has been implemented in the internal printing structure of the

language montor. When a document is opened, printed, and closed, the language

monotr will check the printer status before and after printing and will also react to write

errors if any occur. It will then set the printer status and raise the error event.

• Monitoring while idle

An internal status thread has been implemented which reads printer status and

provides changed status information in the same manner. It will set the status and

raise an error or status event. Therefore, it is not necessary for any other monitoring

loop to be implemented, simply wait for an event in the application’s idle loop.
