Title:
SERIAL DOT PRINTER
Document Type and Number:
Japanese Patent JP3222971
Kind Code:
B2
Abstract:

PURPOSE: To achieve the increase of a processing speed, the reduction of the load of a controller and the reduction of memory capacity by performing the masking processing to printing data for mosaic printing in a hardware manner.
CONSTITUTION: A mask circuit 14 equipped with a means generating the mask signal of the pulse pattern synchronizing to the vertical synchronizing signal VSync outputted from a controller and a means masking the printing data signal DATA-IN outputted from the controller 11 in a bit unit by the mask signal/MASK generated from the mask signal generating means is interposed between the controller 11 and a printing head 15. The printing data signal outputted from the controller 11 is arbitrarily masked by the mask circuit 14 to be applied to a printing head part 15.
