There are two ways to stop a print job. The normal way is to close the job by calling the PrintClose function at the end of the print job. The other way is to cancel the job by calling PrintCancel.
PrintClose sends the current page to the printer or spooler, closes the print job, and activates the window from which the printing started. After you execute a PrintClose function call, any function calls that refer to the job number fail.
PrintCancel ends the print job and deletes any output that has not been printed. The PrintCancel function provides a way for the user to cancel printing before the process is complete. A common way to use PrintCancel is to define a global variable and then check the variable periodically while processing the print job.
Assume StopPrint is a boolean global variable. The following statements check the StopPrint global variable and cancel the job when the value of StopPrint is TRUE:
IntJobNbr
JobNbr = PrintOpen()
//Set the initial value of the global variable.
StopPrint = FALSE
//Perform some print processing.
Do While ...
.
.
.
// Test the global variable.
// Cancel the print job if the variable is TRUE.
// Stop executing the script.
If StopPrint then
PrintCancel(JobNbr)
Return
End If
Loop
