2.1.2 Print Signal Sequence
0017-4696

The signal sequence from when the printer receives the print signals until printing starts is shown in Figure.

F-2-2

a) The printer driver on the host computer transmits print data, including command data, to the printer after

compressing the image data, without resolution, color and 12-color binarization conversion.

To achieve high-quality image output, the image processing table data used for image data color conversion and

binarization conversion are generated as command data to meet the Media Type and other specifications of the

printer driver.

b) This printer receives print data from the individual interfaces on the main controller, transmitting the received

print data to ASIC (IC1).
