LaserWriter Pro Software
Interpreter Parameters 41
Device Parameters 3
You may set device parameters using the setdevparams operator, and you may read
them using currentdevparams. Like system parameters, device parameters require a
password, are global to the PostScript environment, and have the same persistence
characteristics. Some device parameters can be stored in nonvolatile memory.
Device parameters are different from both system and user parameters in that device
parameters may be interdependent. This means that the legality of a given parameter
may depend on the value of another parameter.
Device parameters fall into sets that correspond to a particular device, such as
%Serial%, %disk2%, and so on. Even if two products have the same device, the
parameters in the set might be different because the hardware support for that device
is different.
File System 3
The file system supported by the LaserWriter Pro printer is described in the PostScript
Language Reference Manual. The following restrictions apply to the file system:
■ Filenames cannot end with a slash (/), or contain adjacent slashes (//).
■ Filenames may not contain the colon character (:)
■ There can be no more than 31 non-slash characters between each slash character, and
the total number of characters in a filename may not exceed 255.
■ The printer itself uses SCSI ID 6, so you may not use this ID for any other device.
■ The LaserWriter Pro file system requires that you close a file before deleting it.
Otherwise, an invalidfileaccess error occurs.
■ When you reformat a hard disk attached to the printer, you should turn off the printer,
and then turn it on again.
Note
Several parameters are in units of pages. A page is exactly 1024 bytes. ◆
StartJobPassword string null Any string ≥ 32 characters is not
allowed. Value is persistent across
power cycles.
ValidNV boolean true Refer to the Program Language Reference
Manual Supplement.
WaitTimeout integer 60 ≥ 0. Value is persistent across
power cycles.
