CHAPTER 3
LaserWriter Pro Software
Interpreter Parameters 45
■ with pending parameter sets, the set names contain the suffix _Pending. This is a
read-only set, and it provides information about the settings that will be in use at the
beginning of the next job on the corresponding channel, assuming that there have
been no previous parameter changes.
■ with RAM parameter sets, the set names have no suffix. This is a read/write set, and it
allows you to make changes to the printer that last only until the printer is rebooted.
Note
The hardwareiomode and sethardwareiomode compatibility
operators are provided for PostScript Level 1 applications compatibility
only. Since Level 1 implementations of PostScript are backed up in
EEROM, these implementations are simulated in Level 2 using the
nonvolatile parameters sets. You may therefore access them only from
the nonvolatile parameters switch setting on the LaserWriter Pro printer
(switch position 6).
◆
Note
Since sethardwareiomode provides backward compatibility and is
not supported on previously existing EtherTalk implementations, it does
not support the %EtherTalk_NV% parameter set. ◆
Table 3-12 summarizes the relationship between the sets.
Tables 3-13 through 3-17 list the factory default values of the parameter sets. The values
of the RAM and pending sets are determined by the values of the nonvolatile set.
The PostScript Language Reference Manual Supplement describes the semantics for each
parameter.
