Overview
1-4 C252
When a print job is received during copying, the data is stored in the memory
of this machine. When copying is complete, the print job is automatically
printed.
Flow of the Computer Faxing Operation
Conventionally, faxes are sent by loading an original into a fax machine and
sending it.
With computer faxing, you can send a fax directly from your computer with-
out using any paper.
Transmission commands sent from the application are received by the print-
er 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 or AppleTalk) when this machine is used as a network printer. The data
is then delivered from this machine to the printer controller, which performs
image rasterization (development of output characters and images to bitmap
data). Finally, this data is stored in the memory of this machine and transmit-
ted like a conventional fax job.
