Interpreter Parameters 47

Communication Device Parameters 2

The LaserWriter 16/600 PS printer has four communication ports that implement seven

communication channels:

■ an 9-pin mini-DIN connector is conﬁgured to use LocalTalk protocol and supports the

%LocalTalk% channel

■ a Centronics 36-pin parallel port supports the %Parallel% channel

■ a 14-pin AUI connector supports the %EtherTalk%, %LPR%, %NetWorkInterface%,

%PrintServer%, and %RemoteServer% channels

Each channel has three related parameter sets:

■ nonvolatile

■ pending

■ RAM

The factory default values for the RAM and pending parameter sets are listed in the

tables in this section. The default values for the nonvolatile parameters are the same

except that the /Interpreter parameter is always /PostScript.

PhysicalSize integer ROM dependent Indicates the size of the media. This value

is in pages if page size is indicated by the

BlockSize parameter. The value is only

valid when the device is mounted. A value

of zero indicates the device is not mounted.

Removable boolean false Indicates whether the device supports

removable media.

Searchable boolean true Indicates whether the device supports ﬁle

system search operations without

specifying a device.

SearchOrder integer 11 Indicates the priority at which a device

searches for a ﬁle when no device has been

speciﬁed. Lower values indicate a higher

priority.

Type name /FileSystem This value is always /FileSystem for

%disk0% devices.

Writeable boolean false Indicates whether the ﬁles on the device

can be opened for write access. This

parameter can be set to true or false

only during the device mounting

operation.
