PC-FAX transmission procedures

Usually, for sending a fax, hand-written or printed documents are loaded on the fax machine, and then sent.
Using the fax driver allows you to directly send a fax without using paper simply by operating the computer
(PC-FAX transmission).
Data sent from the application is received by the fax driver.
The data is sent to this machine via the USB interface for USB connection or via Ethernet (TCP/IP, IPX/SPX)
for network connection. Then the data is passed from this machine to the printer controller. The printer
controller rasterizes images (expands output target characters and images to bitmap data). This data is
accumulated in the memory of this machine, and sent as a fax in the same manner as usual fax jobs.
