Introducing the A758 USB Printer
The A758 USB is an extremely fast, quiet, and reliable point-of-sale printer. It
consists of two specialized printers in one compact package: a thermal printer on
top that prints receipts, and an impact slip printer in front to print on forms and
checks that you insert. The thermal printer is optimized for ease-of-use in busy
environments. There is no ribbon or ink cartridge to change, and you load the
paper by simply dropping in a new roll. The impact printer provides the power
and flexibility necessary to print on checks or multi-part forms up to five plies, in
a wide variety of sizes and orientations.
The A758 easily fits in anywhere. It connects to any host computer that uses the
standard RS-232C or USB (Universal Serial Bus) interface. An IEEE 1284 Parallel
interface is also available. The printer’s standard command set allows it to work
with software written for TPG, Inc., or other ESC/POS™ compliant printers. A
variety of sensors enable the printer to communicate its status. The printer’s
journal is kept electronically by the host computer.
Several state-of-the-art check-handling options are also available. The Magnetic
Ink Character Recognition (MICR) option enables the printer to read the special
codes printed on checks and send this information to the host computer to verify
the check. The Check Flip option saves transaction time by making check
handling a one-step process—after reading the front of the check and printing on
the back, the printer is able to flip the check over and print on the front of the
check.
This section describes the printer’s features and options in more detail.
About the Universal Serial Bus
The Universal Serial Bus (USB) is a peripheral bus for personal computers that
was first released in January 1996. Since that time, virtually all Intel Architecture
personal computers have the hardware to support USB, and a large number of
computers exist that have both the hardware and software support required to
interface with USB peripherals.

Chapter 1: About the Printer 3
A758 USB Thermal Receipt and Impact Slip Printer: Owner’s Guide 189-9200399 Rev.A A758-D100 12/04
Advantages of USB Connections
USB has a number of advantages over legacy connection schemes (e.g., serial RS-
232C, parallel IEEE 1284). These advantages include:
♦ High Speed: up to 12 MB/second for high-speed devices.
♦ Plug and Play: Devices are automatically recognized and configured at
installation.
♦ Hot plug: Bus supports installation and removal of devices with the power
applied.
♦ Up to 127 devices: One host can support up to 127 devices with the use of
hubs.
♦ “Free ports”: Most PC architecture machines contain two USB ports in the
base hardware.
These advantages have become attractive to the POS industry for a couple of
reasons.
Additional POS devices. Some POS systems are required to host more
peripherals than can be supported by two RS-232C ports typical in a platform.
With the addition of one (or two) USB connectors, the platform can now support
the additional devices that had previously required a serial port expander card.
Higher bandwidths. New devices coming into use have bandwidth
requirements that are higher than the bandwidth that can be supported on
legacy interfaces. These devices include image scanners and printers. As the
speed and capability of POS printers increases, the performance of the printer in
an application can become limited by the speed of the communications interface.
USB provides ample bandwidth to support current and future POS printer
requirements.
Advantages of the TPG, Inc. USB Solution
TPG, Inc. has eliminated any cost associated with porting applications to USB by
implementing a USB solution that simulates standard serial communications in
Windows 95 (OSR2.1 or later), 98, and NT 4.0 (Service Pack 3 or higher).
Application developers need only redirect their software to the virtual serial
ports created by the TPG, Inc. USB solution to use the printer.

The set of options installed on a particular printer can be determined by looking
at the printer's model number. The printer's model number appears on a label on
the right side of the printer. Four-digit model numbers are assigned to the
various A758 models based on the following formula:
♦ The first digit indicates the release vintage and color of the printer's case.
♦ The second digit indicates the amount of flash memory installed in the
printer.
♦ The third digit indicates whether the printer has the MICR and/or check flip
features.
♦ The fourth digit indicates whether the printer has a knife for cutting receipts.
For example, a printer with model number A758-1015 has a standard color case,
512K of flash memory, the MICR feature, and a knife for cutting receipts.

A758-D100 12/04 189-9200399 Rev.A A758 USB Thermal Receipt and Impact Slip Printer: Owner’s Guide
Checking for USB Support on the Host Computer
If the A758 is equipped with a USB interface, the host computer must be
equipped and setup properly. If it is not, you will need to install a USB interface
card. With the required hardware in place, Windows 98 and 95 (OSR2.1 or later)
natively support plug-and-play USB with a built-in driver; Windows NT does
not, and the TPG, Inc. Windows NT USB driver needs to be installed.
IMPORTANT: You will need to have internet access to download the USB drivers from the
TPG, Inc. Web site: http://www.TPGprinters.com.
Host Configuration
Verify that the proper hardware has been installed in the host computer.
Windows 95 and 98:
1. Open the Control Panel.
2. Click on System (Windows 98) or System Properties (Windows 95).
The Windows 95 operating system version should read 4.00.950 B. If your
system is not current, you will need to upgrade to either Windows 95
(OSR2.1 or later) or Windows 98 before proceeding.
3. Click the Device Manager tab.
4. In the Device Manager window, scroll down the list of installed hardware
devices until you find an entry for “Universal serial bus controller.”
If this entry exists, your host computer is set up for USB operation. If this
entry does not appear:
♦ Consult your computer documentation to see if USB must be enabled in
the BIOS setup.
-or-
♦ Install a third-party USB card, according to instructions provided with
the card.
Windows NT:
To see if your computer is USB-compliant, look at the back.
♦ If it has a USB connector port, your hardware is all set.
Note: Even though the host may have a USB port, Windows NT does not
natively support plug-and-play USB because it does not have a built-in
driver. You will need to load the TPG, Inc. Windows NT USB driver
(see “Installing the USB Printer Drivers”).
♦ If the connector port is missing, you will need to install a third-party USB
card, according to the manufacturer’s instructions.
Note: For Windows NT units requiring the installation of a card, a Windows
95
or 98 USB card can be used with the TPG, Inc. Windows NT driver.

The A758 printer takes up relatively 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 (with the USB interface up to 15 feet) from the host computer and
power supply.
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. Leave several inches around the printer for
connecting and accessing the cables.
If the printer has an optional Magnetic Ink Character Recognition (MICR) check
reader installed, you may need to make additional adjustments to the printer’s
location. Because devices such as CRT monitors or large metal surfaces affect the
printer's magnetic field, they can cause intermittent check reading errors.
