The AXIS 1620 allows the printer driver to communicate directly
with the printer and consequently facilitates complete functional
control over print jobs, e.g. automatic downloading of fonts not
resident in the printer.
This functionality has backward compatibility with older printers and
Macintosh computers, which means that the AXIS 1620 can generate
appropriate responses to Macintosh printer queries, when the
connected printer does not support bi-directional communication.
You simply need to print a document from the Macintosh computer
to verify communication to the chosen printer. The basic installation
can be considered complete if the print test is satisfactory. The AXIS
1620 is now ready to use as a print server.

Server Technical Reference on the AXIS Online CD.
The Binary Communication Protocol (BCP) and the Tagged Binary
Communication Protocol (TBCP) are communication protocols used
by the serial and parallel ports of a printer. They allow 8-bit binary
data in files concurrent with the use of some control characters, for
communication and print job control. TBCP is required for printing
with a binary data stream on some printers.
