INTELLIGENT PRINTER SWITCH

3.1 Configuring Your Intelligent Printer Switch plus
Figure 3-1 below shows the rear panel of an eight-port Intelligent Printer
Switch
plus (IPSP). On a six-port model, the top two connector slots on the left
would be empty. On all models, Port 1 is a dedicated printer-output port. Port
2 is a bidirectional input/output port. The remaining ports are all computer-
input ports.
Refer to Figure 3-1 as you read the configuration instructions.

ODELS
Set the option switches on the underside of the IPSP to the settings required
by your system. (See Figure 3-2 on the next page.) The default settings are
suitable for most installations. Note that the option switches are read only
when the IPSP is first powered on.
Timeout
The IPSP switches between users on a timeout basis. If no data has been sent
from the current user for the timeout period, the IPSP will switch to the next
user. A timeout period of 16 seconds (the default setting) is suitable for most
systems.
Mode
If you are using fast PCs and printers with enhanced parallel ports, burst
mode may speed up your printing performance. For most systems normal
mode (the default setting) will give the best overall performance.
