1.1.2Flow of the PC-FAX operation
Conventionally, faxes are sent by loading an original into a fax machine and sending it.
With the fax driver, you can send a fax directly from your computer without using any paper
Transmission commands sent from the application are received by the fax driver.
Data is transferred to this machine through the USB interface (when using a USB connection), through the Ethernet (TCP/IP or IPX/SPX) (when using a network connection), or through the parallel interface (IEEE 1284) (when us- ing a parallel connection), and then the data is transferred from this machine to the printer controller. Image rasterization (bitmap data created from output text and images) is performed by the printer controller. This data is stored in the memory of this machine and transmitted like a conventional fax job.
