Printer Installation
A Liquid Controls meter system with a LCR-II typically
includes an Epson slip printer or roll printer. Installation
is the same for both printers.
LCR-II’s are typically shipped with a black-sheathed data
cable prewired to terminals J1 and J3 on the LCR-II CPU
board.
To install the printer:
1. Find a convenient mounting spot in the truck cab where
drivers can easily operate the printer.
2. Clean the mounting spot and the bottom of the printer
with alcohol for the best stick.
3. Attach the Velcro to the mounting spot and the bottom of
the printer and fasten the printer to the mounting spot.
4. Connect the data cable to the RS-232 data port on the
back of the printer.

For connecting power to the printer see pg. 29.
See instructions on pages 17 for routing the data
cable from the back of the truck to the cab.
To communicate via true RS-232 protocol, the +VP Red wire must
be connected to the J3 terminal block at terminal 47 (not 46).

Installation
Before connecting power to the LCR-II and the Epson
printer, ground the printer to the truck cab floor. Epson
printers sold for truck installations are all grounded in the
same manner.
To ground an epson printer:
1. Remove one of the mounting bolts fastening the printer
mounting brackets to the truck cab floor.
2. Place one end terminal of the ground wire over the
mounting bolt and return the bolt to its original place.
3. At the back of the Epson printer, remove the silver ground
screw marked “FG”.
4. Place the other end terminal of the ground wire over the
ground screw and return the screw to its original place.
5. Check the strap for a good ground connection (see page
13).
The Epson Printer Ground Wire Kit contains an additional ⅜" ring
terminal for printer brackets not purchased from Liquid Controls
