Problems solved by technology

[0025] That is, since the host computer executes meaningless real-time command processing with meaningless timing, for example, the host computer side is not prepared to receive status data from the printer, and compatibility with the printer is not taken.

Abstract

Evaluating means in a printer controller detects whether a command data stream for printing image data to a printer contains a specific data sequence. When the specific data sequence, such as the data sequence of a real-time command, is present in the command data stream, division means generates a plurality of command data stream segments not containing the specific data sequence and printing image data identical to the image data of the original data stream; sending means then sends the plurality of command data stream segments to the printer.

Description

technical field [0001] The invention relates to a printer control device and a printer control method. In particular, it relates to a printer control device and a printer control method capable of preventing malfunction of the printer when printing graphics data including the same data sequence as that of the real-time command to a printer that processes the real-time command. Background technique [0002] Printers (printing devices) are widely used as devices for printing characters and graphics on printing media such as paper. Such a printer is connected to a host computer (information processing device), and the host computer sends data strings for printing characters and graphics and data strings for controlling the printer itself to the printer. Therefore, such a host computer functions as a printer control device. [0003] Data sent from the host computer to the printer can be viewed as either a string of bits or a string of bytes. In particular, in printers, the co...
