Printing Flow
When using this printing system as a printer, the flow of the main process is
described below.
Print commands transmitted from the application are received by the printer
driver.
Data is transmitted to this machine over a parallel interface (IEEE 1284) when
this machine is used as a local printer, over a USB interface when this ma-
chine is used as a USB printer, or over an Ethernet interface (TCP/IP, IPX/
SPX, AppleTalk) when this machine is used as a network printer. The data is
then delivered from this machine to the printer controller, which performs im-
age rasterization (development of output characters and images to bitmap
data). Finally, this data is printed from this machine.

Note
The parallel and USB interfaces cannot be used simultaneously.
Original documents can be scanned in the copy function or network scan
function while this machine is operating as a printer.
To use this machine as a copier, press the [Copy] key on the control panel.
