Abstract
Abstract A printer apparatus is provided with a frame memory for storing a printing pattern, a printing head driven in accordance with the printing pattern stored in the frame memory, and a processor for producing a plurality of graphic patterns in the frame memory in accordance with a plurality of items of printing data which are externally supplied, to thereby form a printing pattern. The processor of the printer apparatus includes a buffer memory and a CPU. The buffer memory stores image distribution data indicating a frame memory area which is occupied by the image portion of the graphic pattern corresponding to printing data to be changed and from which the marginal portions of the graphic pattern is excluded. When printing data which should be used in place of the printing data to be changed is supplied, the CPU reads the image distribution data relating to the printing data to be changed out of the distribution data memory, and clears the frame memory area specified by the image distribution data.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A printer apparatus, comprising: a frame memory for storing a printing pattern; a printing head driven in accordance with the printing pattern stored in the frame memory; and processing means for producing a plurality of graphic patterns in the frame memory in accordance with a plurality of items of printing data which are externally supplied, to thereby form a printing pattern, wherein said processing means includes a distribution data memory for storing image distribution data indicating a frame memory area which is occupied by an image portion of a graphic pattern corresponding to printing data to be changed and from which marginal portions of the graphic pattern are excluded, and area-releasing means, responsive to the supply of printing data which should be used in place of the printing data to be changed, for reading image distribution data relating to the printing data to be changed out of the distribution data memory and for clearing the frame memory area specified by the image distribution data.
Claim 2
Dependent Claim
