Summary

ABSTRACT

With the recent development of cheap highly functional laser printers and Raster Image Processors, there has been an upsurge of interest in languages for interfacing to these devices. An approach to the design of such a Page Description Language is described, the primary design requirement being a clean interface which is an easy target for translators from various front-end systems. The design of an actual PDL, the Chelgraph ACE language, based on these principles is described. Finally the ACE language is reviewed in the light of experience gained in its use.

Introduction

This paper discusses some issues relevant to the design of a Page Description Language (PDL). A PDL is a type of language commonly used for communicating page information from a composition system to an intelligent page printer. These languages are usually specified by the printer manufacturer as an input language, but device-independent outputs from some composition packages, for example DI-TROFF, are also PDLs. I also present a particular PDL, the ACE language, which has been designed by us at Chelgraph and implemented on our Raster Image Processor, the features of ACE itself have been described elsewhere [Chel84, Harris84].

What Is a PDL?

There have always been languages for communicating page information to typesetters and printers. Until recently the capabilities of computer output printers have been very limited, so their input languages have been simple ASCII formats modified by escape codes. Typesetters such as the Autologic APS 5, on the other hand, have quite complex input languages with a syntax and tens of commands.
