Port Number to either 515 or 9100, depending on whether you wish to commu-
nicate with the printer using the LPR (
515) or JetDirect (9100) protocol.
Note: The LPR protocol does not provide bidirectional communication with the
printer. Consequently the printer cannot report error messages when using this
protocol. Use the port number
9100 to avoid this.
If you are using an external JetDirect print server you must set the
Port Number
to
9100, or a similar number.
Some external print servers can drive several printers simultaneously. In this
case the different physical connections or ports have their own numbers (which
may vary with the type of server). For example, on an external JetDirect unit
with three output ports, the physical ports named 1, 2, and 3 have port numbers
9100, 9101, and 9102.
The RIP supports the use of another printer connected to the same print server.
For example, two computers running the RIP and driving the same print server
can address any compatible printer connected to that server.
Output: Quality
The options that appear in this menu are methods of driving the printer, which
offer combinations of speed and image quality that may depend on the printer’s
capabilities. Refer to your printer documentation for details of the relative
merits of these quality settings.
If you are using supplied calibration profiles it is recommended that you use the
Best option.
The
Printer Default option uses the quality setting specified in the control
panel on the printer.
Output: Compression mode
The options that appear in this menu are methods of coding the data sent to the
printer. The coding methods can affect the time taken to transfer data to the
printer.
None sends the data uncompressed.
Run-Length Encoding performs a lossless compression that enables the exact
data to be recreated. For many images, using
Run-Length Encoding will
reduce the size of the data and the time taken to transmit it. For some very com-
