Product Strings 2

Table 2-2 lists values assigned to the product strings associated with the LaserWriter

Select 310 printer.

Software Parameters 2

This section deﬁnes the software parameters that enable you to set up and conﬁgure the

LaserWriter Select 310 printer. These parameters fall into two broad categories:

■ communication device parameters

■ compatibility operators

Communication Device Parameters 2

The LaserWriter Select 310 printer has two communication ports: an RS-232 serial port

and a Centronics 36-pin parallel port. The section “Setting Communication Parameters,”

later in this chapter, deﬁnes communication channel parameters. Chapter 3,

“Communication Channels,” provides detailed information on this subject.

The LaserWriter Select 310 printer does not need to change parameters for the parallel

communication channel, nor is it equipped to do this.

Compatibility Operators 2

The PostScript language has undergone a number of signiﬁcant extensions. The language

is designed to be a universal standard for device-independent page descriptions, but each

PostScript language implementation supports features and capabilities particular to that

implementation. Appendix D, “Compatibility Strategies,” in the PostScript Language

Reference Manual, second edition, presents guidelines for taking advantage of language

extensions, while maintaining compatibility with PostScript interpreters.

Level 1 implementations provide a collection of device control and system parameter

conﬁguration operators and procedures, most of which are deﬁned in the dictionary

statusdict. The contents of statusdict are product dependent, although an attempt

has been made to maintain a consistent speciﬁcation for common features. It is the

dictionary for product-speciﬁc operators and other deﬁnitions.
