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 A776/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” specification. The USB driver may use two pairs of bulk pipes, so USB functions are an enhancement of
those defined in the A776/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 configuration planning and assigning fixed 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 configuration 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 configure 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 configured to be able to find 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 office
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 flow control is not an available option. Please
use DTR/DSR instead of XON/XOFF handshaking for image transfer.
