Printing process
Application uses the Printer Library of the Print System to create and print out the print data.
Printing from an application means a process up to the point the spooler creates a spool file via the
above described printer driver. The actual print job is where the spooler, after creating the spool
data, sends the print data via the language monitor/port monitor to the printer.
If printing begins, the corresponding icon is displayed in the Task Tray as shown below. Click this
icon to open the On-Printing dialog.

Monitoring the printer
With the Print System, the finish of the application-side print job is at the point in time the spool
file of the print data is created. Subsequent monitoring of the printer is performed by the language
monitor via the port monitor. If the language monitor detects a printer error, it displays a dialog
box to post notice of the error.
Error display dialog
If an error occurs during printing, this error dialog is invoked.
