Abstract

PURPOSE:To prevent character patterns sent from a host computer from erasing when the power supply is turned off, by adding an EEPROM in addition to an ROM and RAM. CONSTITUTION:When the power supply is turned on and character patterns are sent from a host computer 6, the character patterns are stored in an EEPROM 7. When the power supply is turned off, information stored in an RAM 4 is erased, but the information stored in the EEPROM 7 is not erased because the EEPROM 7 is a nonvolatile memory and character patterns sent from the host computer 6 remain stored. Therefore, when a print instruction is issued, necessary character patterns are read out from the EEPROM 7 and printed by means of a print head 9. In this way, character patterns sent from the host computer 6 can be kept stored even when the power supply is turned off.

Conventionally, in a printer, a control device shown in FIG. 1 receives a printing command from a host computer and performs printing. In other words, (11 is a microprocessor that controls the printer, (2) is an E3JOM that stores character patterns for printing, and when the above microprocessor (1) receives a printing command, the microprocessor (1) The character pattern that matches the received code is read from the OM (21) and printed by a printing mechanism (not shown).After that, the character pattern to be printed is changed each time it is used. i(, A M (4) built-in printers have appeared, and new character patterns 6, sent from an external host computer (6) via an interface (5)
Devices with IR functionality for reading and writing have also been put into practical use.
