CHAPTER 3
LaserWriter Pro Software
56 Compatibility Operators
Device control and configuration of system parameters in PostScript Level 2 are
accomplished in a standard way in the language through the device setup and
interpreter parameter operators.
Level 1 PostScript language driver software frequently depends on statusdict
operators that were present in PostScript Level 1 products. To maintain compatibility
with these products, a collection of statusdict operators and procedures is included
in each Level 2 implementation. Most of these functions are implemented as PostScript
language procedures that call setpagedevice or appropriate Level 2 operators with
appropriate arguments.
Adobe Systems recommends that you do not use the statusdict operators in
PostScript Level 2 drivers, since the presence or absence of the operators depends on the
product. Instead, you should use Level 2 standard operators.
The compatibility operators present in the LaserWriter Pro printer appear in three
dictionaries: statusdict, userdict, and systemdict. Table 3-23 lists these operators
by dictionary group.
