Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] figure 1 It is a block diagram showing the configuration of the printing system 1 according to the embodiment of the present invention.

[0024] figure 1 The illustrated printing system 1 is a system in which a host computer 10 and a printer 20 (recording device) are communicably connected, and based on data output from the host computer 10 , the printer 20 outputs a printed product.

[0025] The host computer 10 is configured to include a CPU, ROM, RAM, etc. not shown, and includes a control unit 11 that executes a program to collectively control each unit of the host computer 10 . The control unit 11 executes the operating system 12 to control each unit of the host computer 10 and the printer 20, and executes the application program 14 on the operating system 12, thereby realizing functions such as document creation and print data management. The application...

Abstract

The invention relates to a recording device and a control method for the recording device. In the recording device, the capacity of the memory where font data is stored is inhibited, and the delay caused by the decompression of compressed data is prevented. A printer comprises a printing unit; a ROM storing compressed font data for each character, and storing a compressed data index establishing correspondence between character codes and addresses where the compressed font data of characters corresponding to each character code are stored in the ROM; a compressed data obtaining unit which obtains the addresses where the compressed font data corresponding to the character codes of characters of a printing object are stored, and reads the compressed font data according to the obtained addresses; a decompression unit for decompressing the compressed font data in a font decompression area; and a printing control unit for controlling the printing unit to print the characters of the printing object based on the depressed data.

Description

technical field [0001] The present invention relates to a recording device and a control method of the recording device. Background technique [0002] Conventionally, there is known a recording device that stores (embeds) font data for recording characters in a storage medium such as a ROM, and records characters based on the stored font data (for example, refer to Patent Document 1). The recording device described in Patent Document 1 performs a process of storing font data in a compressed form in the ROM in order to reduce the capacity of the ROM, and reading and decompressing the font data from the ROM at the time of recording. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 07-137341 [0004] However, since it takes time to decompress the compressed font data, a delay occurs when a plurality of characters are continuously recorded. Therefore, for example, there is a method of reading font data from ROM in advance and decompressing it. However, in ...
