Non-volatile memory data initialization/rewrite apparatus for a printer

Abstract

Disclosed is a printer which will carry out initialization or rewriting of data in a non-volatile memory in response to a control command sent from a host machine, and execute printer initialization, based on the initialized or rewritten data, by a control command sent from the host machine. Unlike the prior arts, therefore, it is possible to perform initialization of the printer based on the initialized or rewritten data, without involving a troublesome switching operation and without requiring an operation of powering off and then on the printer or resetting the host machine. A printer according to another aspect of this invention is designed to print out data in the non-volatile memory in response to a control command sent from the host machine. It is therefore possible to print out the contents of the non-volatile memory for confirmation without involving a troublesome switching operation in this case too. Further, if the structure of the second aspect is added to the structure of the first aspect, it is possible to easily check if the data in the non-volatile memory has been surely initialized or has been correctly rewritten.
