APPLETALK CONFIGURATION
PostScript Mode (Standard or Tagged Binary)
In this mode, you send data using the standard (STD)
protocol PostScript page description language, or using the
tagged binary communications protocol (TBCP).  The STD
PostScript language sends and receives data in ASCII.  Some
of the 256 characters used by the PostScript language are
interpreted as control functions only and cannot be
transmitted as data.  The control functions are as follows:
End of job
Xon
Status (for example, printer idle)
Xoff
Abort (for example, cancel)
The TBCP protocol allows individual applications to enable or
disable binary communications on a per-job basis with begin
and end protocol functions.  All 256 characters can be
interpreted as data, and some can also be interpreted as
control functions.  The TBCP protocol PostScript language
uses the control functions listed for the STD protocol
PostScript language, as well as the following:
Ctrl A (control functions are interpreted as data)
Begin protocol
End protocol
When AppleTalk is set up in STD/TBCP protocol PostScript,
the printer detects standard protocol PostScript and
processes the files accordingly.  Data sent in binary can be
image data, PostScript language objects and numbers, and
strings.  This setting is used primarily in a mixed network
environment with gateways from DOS networks (for
example, Novell) to AppleTalk.  This setting is also used
where PC AppleTalk cards are used.  AppleTalk network
architecture alone has no need for TBCP, because it carries
control functions out of band (as separate packet types) and
arbitrary 8-bit binary data can be sent directly without any
additional encoding.
PostScript Mode (AppleTalk)*
This setting is used primarily for AppleTalk if the printing
environment is not a mixed network.  In this mode, all 256
(8-bit) characters are sent to the printer as data.  PostScript
control functions are handled by the AppleTalk protocol
independently from the data.
Hexadecimal Dump mode
This setting is not supported by the current MRP Macintosh
software, including the MRP driver and the Font Downloader.
Host queries sent by the above software cannot be
interpreted by the printer in hexadecimal dump mode and
data cannot be dumped accordingly.
