The B780 ColorPOS® printer without imaging
Description of B780 printer without imaging
The TPG B780 is a small, ecient printer for banking.
It features fast black and white or ColorPOS® receipt
printing. The B780 also features an impact printer
that prints checks or multi-part forms that you insert
manually. These forms can have up to four parts and can
be in a variety of sizes. Built-in Magnetic Ink Character
Recognition (MICR) check validation is an optional
feature of the B780 printer.
The B780 ts easily in spaces where no other hybrid
printer can and connects to most host computers via
the Dual 9-pin /USB interface or 25-pin RS-232 interface.
Powered USB and Ethernet interface are also available.
The printer’s standard command set allows it to work
with software written for TPG or other compliant
printers. A variety of sensors enable the printer to
communicate its status to the host computer. The printer
also has an electronic journal feature.
The easy-to-use thermal printer requires no ribbon or
ink cartridge. Load new paper by simply opening the
clamshellTM receipt cover and dropping in a new roll.
This section describes the printer’s features and options
in more detail.

The B780 ColorPOS® printer with imaging
Chapter 2: About the Printer and Imaging

Description of B780 printer with imaging
The TPG B780 ColorPOS® printer is also available with
an imaging feature. This allows you to make scanned
images of checks, ID cards, or other items, and then
print those scanned images. The imaging module
is added to the B780 base printer, so the imaging
printer has all of the same features and electronics as
the original.
TPG can build a dual sided imaging capable printer at
the factory, or you can install an upgrade kit yourself on
an existing B780 ColorPOS® printer and upgrade the
original printer.
Items to be imaged can be inserted either at the
standard slip position or the scanner front top. Front
top inserted items can range in size and thickness from
receipt paper and checks to hard laminated ID cards,
depending on use of either the slip entry or the readily
accessible top front feed entry. Documents can exit at
either of the entry points or at the back of the at top,
going over the receipt print section.
CAUTION
To prevent document or printer damage, top inserted
documents cannot be fed down to the curved paper
path of the slip station.

Operating systems supported by the imaging feature
TPG provides with each printer a UPOS compatible driver for the following operating systems for any applications that
use TPG printers:
1. Windows 98SE
2. Windows 2000
3. Windows XP
4. Linux, Red Hat version 9.0 or later (this is a Java POS driver)
TPG may provide drivers for other operating systems in the future.
Communication interfaces supported by the imaging feature
Ethernet/RS232 Dual Interface Option:
The dual capability interface consisting of RS232, capable of running at TPG standard speeds between 9600
•
baud and 115.2K baud, and an Ethernet 10/100 base-T interface. Protocols implemented for Ethernet are the
same as for the B780/B780 FS Ethernet adapter: IP address BootP, PING, raw TCP data transfer, LPD, and TELNET
(including Reverse Telnet).
Either interface can be used for Printer commands and/or Image transfer (i.e. RS232 - printer commands and
Ethernet-image transfer). However, TPG does not recommend that the RS232 interface be used for image
transfer as it is too slow.
USB/RS232 Dual Interface Option:
The dual capability interface consisting of RS232 and a USB 1.1 interface, compatible under the USB 2.0 “full
•
speed” specication. The USB driver may use two pairs of bulk pipes, so USB functions are an enhancement of
those dened in the B780/B780 FS.
If a USB cable is plugged into the interface card, the RS232 interface is disabled. Therefore, printer commands
and image transfer can be done either on the RS232 interface or the USB interface. TPG does not recommend
that the RS232 interface be used for image transfer as it is too slow.
Using Ethernet requires site conguration planning and assigning xed IP addresses. Generally, one side acts as a client
(and has to know the server IP address), and the other side is the server, always ready to accept incoming clients. The
Ethernet speed of the host or router should be limited to 100 baseT for now.
To use Ethernet to connect the printer to a hub or router, you will need a standard RJ45 CAT5 cable, or a “crossover”
cable (send and receive pins are crossed) if the printer is directly connected to a host personal computer.
Any logical dual connection uses Ethernet for images and has the printer as client sending images to a server - either
to a shared image archive or to a single host computer (as in demo.) The clients connect and disconnect with each
image transfer. Client conguration requires setting the target server IP address in the printer. The printer default is
192.0.0.192.
If you want a single Ethernet link, you can congure the printer to work as the server, and use a host personal
computer as a client that would connect and keep the connection open for all printing and imaging commands and to
receive scanned data. In this case the personal computer client must be congured to be able to nd the IP address of
the desired print server. In this case you would either assign a regular name to the printer (as is done for oce printers
in Windows) or directly by entering the printer’s IP address (default server address for the demo is 192.0.0.1)
Note: If transmitting images over the RS232 interface, XON/XOFF ow control is not an available option. Please use
DTR/DSR instead of XON/XOFF handshaking for image transfer.

Miscellaneous:
Security It is up to your management to set up and run all security features associated
with using networked printers. Likely your printer uses an Ethernet link, making it
potentially a network peripheral, so to secure image les sent over your network
you can use set the tag feature provided with the system. We expect that each of
your printers will be connected using a standard communications cable to a host
computer, so the data traveling back and forth between the printer and any of
your servers will not be transmitted using an unsecured wireless link. Your printer
is not designed to prevent access to any of the information stored in its ash
memory, but there is absolutely no way to alter any captured image in the printer.

Getting Started
Before setting up the printer, be sure you read and understand each of the sections in this chapter. The sections are
presented in the order they should be performed.
Choose a location for printer without imaging
The B780 printer may be set on or near the host computer.
With the RS-232C interface, you can place the printer up
to 50 feet from the host computer and power supply, and
15 feet with a USB interface. Try to protect the printer
from getting dusty, and make sure it is safe from having
coke or coee spilled on it.
Place the printer on a level surface, and make sure there
is enough room to open the receipt cover to change the
paper and to open the front cover to change the impact
printer’s ribbon cassette.
Be sure to leave enough space behind the printer to
access the cables.
If the printer has a built in Magnetic Ink Character
Recognition (MICR) check reader, you may need to make
additional adjustments to the printer’s location.
Devices such as computer monitors or large metal
surfaces can aect the printer’s magnetic eld and cause
intermittent check reading errors. Be sure to place the
printer away from sources of interference.

The B780 printer with an imaging unit requires very
little counter space and may be set on or near the host
computer. With the RS-232C interface, you can place the
printer up to 50 feet from the host computer and power
supply, and 15 feet with a USB interface. Try to protect
the printer from getting dusty, and make sure it is safe
from having coke or coee spilled on it.
Place the printer with an imaging module on a
level surface, and make sure there is enough room,
approximately 11 inches high, 20 inches long, and 9-14
inches wide, to open the receipt cover to change the
paper, to open the front cover to change the impact
printer’s ribbon cassette, or open the imager cover to
clear a jam.
Be sure to leave enough space behind the printer to
access the cables.
If the printer has a built in Magnetic Ink Character
