Using the Verifone 250 Receipt Printer with MPI 2002

Before You Begin

MPI 2002 v. 1.0.8.x has built-in support for Verifone 250 receipt printers. Support
for this printer was included to provide a cost-effective solution for receipt
printing. Supplies for the Verifone 250 are redily available through a number of
vendors and both new and used Verifone 250 printers can be purchased from a
number of outlets for far less than most other receipt printer models on the
market.

To use your Verifone 250 receipt printer with MPI 2002 you will need to purchase
a special serial (RS232) cable from Verifone or an authorized vendor. (Part
number: 10765-00) This cable can be ordered from Verifone directly for about
ten dollars. Before continuing with this guide, obtain this cable and check to
make sure you have the necessary ribbons, paper rolls, etc. You Verifone 250
receipt printer should have all of the parts shown in Figure 1.1 below.

Connecting The Verifone 250 Receipt Printer

With all of the parts listed in the previous section, we are now ready to connect
the receipt printer to your computer. First, lets assemble the various receipt
printer parts. (DO NOT INSTALL THE POWER PACK AT THIS TIME. ENSURE
THAT THE POWER PACK IS NOT PLUGGED INTO THE WALL.)

Setting DIP Switches

By default, the DIP Switches on your printer should already be correctly set.
However, it is a good idea to check these setting before proceeding. The DIP
Switches on your printer are located under the Ribbon Cartridge. Remove the
Ribbon Cover from the Printer Unit by simultaneously pressing-in and pulling-up
on the grooved thumb button on the front panel of your printer. (Below the printer
nameplate.) If the Ribbon Cartridge is already installed, gently remove it by
pulling up on each side evenly. To the right of the ribbon cartridge assembly (the
rectangular metal box that the Ribbon Cartridge sits over) are the DIP Switches.

Turn the entire Printer Unit clockwise until you are looking at the right-side of the
unit. Your DIP Switches should look like the diagram on the next page. If they
are not, move each DIP Switch using a ballpoint pen or pencil until they all match
the illustration.

Installing The Ribbon Cartridge

Remove the Ribbon Cover from the Printer Unit by simultaneously pressing-in
and pulling-up on the grooved thumb button on the front panel of your printer.
(Below the printer nameplate.) Check to determine if a printer Ribbon Cartridge
is installed. If a Ribbon Cartridge is installed, skip to the section entitled
“Installing Power Pack.”

Place the Ribbon Cartridge face up into the ribbon cartridge assembly. The
Ribbon Cartridge is face-up if you can read the manufacturer’s logo on the top of
the cartridge and the ribbon advance spindle (a small, round, toothed wheel on
the top right of the cartridge) is visible. Ensure the ribbon itself is in front of the
ribbon cartridge assembly. Refer to the Verifone 250 Receipt Printer Manual for
more information.

Turn the ribbon advance spindle clockwise until the ribbon is firmly seated in front
of the ribbon cartridge assembly. Lastly, replace the Ribbon Cover and proceed
to the next section.

Installing Power Pack

We are now ready to install the Power Pack. Before proceeding, ensure that the
Power Switch is in the OFF position. (From the front of the Printer Unit, the
Power Switch will be pushed “back” so that the “0” is down and the “I” is up.) In
the diagram on the next page, the Power Switch is in the ON position.

Locate the Power Pack and plug the small round cable into the back of the
Printer Unit. Refer to the diagram below to locate the correct port. Match the pins
on the power cable with the pins holes on the back of the printer. The power
cable will only fit in the correct port and only in the correct position. DO NOT
FORCE THE POWER CABLE INTO THE PORT. Instead, rotate the power cable
until the pins match the corresponding holes.

Next, plug the Power Pack into an approved wall socket or power strip. It is
strongly recommended that you use a power strip with surge protection when
installing your Verifone 250 Receipt Printer.
