If the application starts (CpStartDoc) the print job, the
spooler begins to create the spool file.
The spooler will start printing after creation of the
spool file has been completed.
(Transmission of the spool file to the specified printer.)
If the application completes the print job, the spooler
also completes the creation of spool file. At this point in
time, print control from the application is terminated.
(From the point in time spooling is completed, actual
printing commences.)
Hereafter, the language monitor monitors the printer.
(Displayed as an icon on the Taskbar.)
Create the print data with the GDI function for the
device context of the printer.
The application first creates (retrieve) the device
context of the printer.
