Adding a remote printer is a bit involved but here you go.
Physical setup
1)
There are 2 ports labeled IDN1 and IDN2 on the back of the printers.
The new remote will be daisy chained off the bar terminal's printer
using these ports. The cable from the workstation will go into one port
on the check printer, the cable to the new remote will go into the other
one. It doesn't matter which port you use, they're on a common bus
line.
2) The IDN ports use RJ11 jacks, not RJ45's. The wiring is straight through pin for pin.
3) There's a bank of dip switches on the back of the printer. #'s 4, 3, 2 & 1 set the ID for the printer.
Its binary, with #4=1, #3=2, #2=4 & #1=8.
Programming Changes
1) set the new printer up as a device.
POS Configurator/Devices tab/Devices button.
General tab

Com Port: 4
2) set the printer up as an order device
POS Configurator/Devices tab/Devices button.
General tab:
Add the printer name
Header: select one or leave blank
Device: the device you just set up
Backup: I'd use the bar's check printer
Redirection Device: the device you just set up
Options Tab:

3) make/modify a print class
POS Configurator/Sales tab/Print Classes button
Look for a Bar print class. If they have one find the order device
you just set up in the Remote Devices list and check it.
Uncheck previously checked Remote Devices for the Bar print class.
4) tell the workstations they can use the new printer
POS Configurator/Devices tab/User Workstations button
Order Devices Tab
Go to each workstation that will be printing to the new device and check it in the order device list.
Obviously, make sure this is done off-hours and make a backup before starting. Start/run "runbackup -n"
