Abstract

본 발명은 레이져 프린터에 있어서 복수의 에뮬레이터를 동시에 가동시킴으로써 복수개의 입력포트로 입력되는 데이터를 모두 처리할 수 있도록 한 것이다.According to the present invention, a plurality of emulators can be simultaneously operated in a laser printer to process all data input to a plurality of input ports.

주지하는 바와 같이 레이져 프린터의 에뮬레이터는 사용자에 의하여 사용전에 미리 선정되고 가동되는 것이며 1개의 포트로만 입력되는 데이타를 처리할 수 있도록 한 것이다.As is well known, the emulator of the laser printer is pre-selected and operated by the user before use, and can process data input through only one port.

그러므로 모든 사용자는 자신의 컴퓨터에 따라 프린터의 에뮬레이터를 수시로 변경시켜 가면서 사용하여야 하는 것이어서 사용상 매우 번거로운 문제점이 있는 것이다.Therefore, all users have to change the emulator of the printer from time to time according to their computer, which is a very troublesome operation.

본 발명은 이러한 번거움을 해소하기 위하여 프린터의 직렬과 병렬데이타 입력용으로 되어 있는 2개의 입력포트를 모두 활용하여 데이타를 입력시키고 이들 입력 포트를 감시하여 데이타가 어느 한 포트로 입력되면 해당 포트에 미리 할당된 에뮬레이터가 가동되도록 하는 방법으로 프린터 자체는 별다른 조작을 하지 않더라도 복수개의 컴퓨터가 원하는 에뮬레이터로 프린터를 가동할 수 있게한 것이다.The present invention utilizes both input ports that are used for serial and parallel data input of the printer in order to eliminate such a hassle, and monitors these input ports to enter the data when the data is input to any one port By allowing the pre-allocated emulator to run, the printer itself allows multiple computers to run the printer with the desired emulator without any other manipulation.

Description

How to run multiple emulators of a laser printer

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명을 실시하기 위한 복수에뮬레이터 가동방법을 보이는 플로우 챠트.1 is a flowchart showing a method of operating a plurality of emulators for practicing the present invention.

제2도는 본 발명을 실시하기 위한 일반적인 하드웨어의 일예.2 is an example of general hardware for practicing the present invention.

Claims

When the printer is powered on (10), the printer stores the emulator 1 (e.g., below) in the allocated area of memory by its operating system (20) and the emulator 2 in another memory area (e.g. Save HPLS (30), jump to port monitoring program of operating system (40), check serial input port and parallel input port (50) and if there is data input, emulator 2 waits (60). The emulator 1 is operated to process the data of the designated number 1 port (70). Thus, in the process of data processing 120, if the input of data continues at intervals of a predetermined time or less, the number 1 If you continue to process data with the emulator and the waiting time for no data input exceeds a certain time, the port monitoring program of the operating system If the data is inputted to the designated port 2, when the data is inputted to the RAM, the emulator 1 is in the standby state 100 and the emulator 2 is operated to process the data (110). In the process of data processing 120, if data input continues at intervals of a predetermined time or less, the data processing is continued with the second emulator, and if the waiting time for which data is not input passes a predetermined time, the operating system The method of operating a plurality of emulators of a laser printer, characterized in that jump (40) to the port monitoring program.
