When using the LaserWriter IISC, printing within an application (such as
MacPaint) that contains a dialog box requiring the "command-period" to
stop printing, you may experience this problem: the "command-period" does
NOT stop or interrupt the printing.
However, if you are printing within an application that uses a dialog box
with a "cancel" button, the cancel button DOES stop the printing.
This is a problem in the LaserWriter IISC driver, not the PostScript printer
drivers. Currently, you CANNOT cancel most print jobs when programs display
a printing message stating "To cancel, hold down the command key and type a
period (.)"
