The application program prepares the data to be printed.
For example, the program might read data from diskette
and send it to the printer to print a user's report.
The printer attachment MPU card is the interface between
the application program in main storage and the printer.
The card contains the printer attachment MPU and the
printer adapter, which permit the system to control the
printers.
