Abstract

A computer interface for a stencil printer includes a data receiving section which receives printing data or program rewriting data from a computer, a data processing section which converts the printing data from the computer into stencil making data according to a running program, and a video data output section which outputs the stencil making data to a stencil printer with stencil making system. The data processing section is provided with a nonvolatile memory consisting of a main program block which is rewritable and stores a main program and a start-up program block which is not rewritable and stores a start-up program. A main program rewriting section rewrites a main program in the main program block when the main program which has been stored in the main program block is invalid or when the data receiving section receives program rewriting data from the computer.
