CHAPTER 2
LaserWriter Select 310 Software
Software Parameters 19
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.
