应用软件中通用打印模块的设计方法

The Method for Designing a Universal Printing Module in Application Programs

本文提供了一种通用打印模块的设计方法,将此法用于编制dBASE应用软件时,可解决打印控制符的通用性问题,使应用软件不需修改就可在多种操作系统版本和打印机上运行,当更换系统或打印机时不用修改程序。

This paper introduces a new method for designing a universal printing module. Thismethod can be used, in printing dBASE application programs, to overcome the nonfeasibility of printcontrol characters at various CCDOS versions and printers. So the programs can be used in various CC-DOS versions and printers with nothing changed.
