2.7.1.3 Overview
0018-3146
LBP3370
The video controller receives print information from external devices (e.g., host computer) through interface cables.
Such print information contains commands used to exchange printer status and unique information as well as PDL data.
The PDL data is converted into a display list by the display list generation circuit, and turned into bitmap data for output to the DC controller. A check may be made
on the printer status using an external device.
