1 Introduction
This document is a Users' Guide, written for the person designing-in, connecting and using the Able
Systems A104B printer controller board for the EPSON M-160 series of 4-needle mini-printer
mechanisms. Please read it carefully before making any connection. The A104B is an enhanced
replacement for the A160B series of controller boards, and shares many features of the range. Every
effort has been made to simplify the transition for existing customers, but of necessity some of the
connections are slightly different.
Throughout this document, the designation A160B can generally be taken to represent the A150B,
A160B, A163B, A164B, and national variants of these products.

3 Pin Connections
The A104B has three external connectors or connection areas, for data and power, auxiliary power, and
the printer mechanism. The locations of these connectors, and the overall PCB outline and fixing
positions, are designed to be identical to those of the A160B. There are also some onboard jumpers.
Please refer to the layout diagram for connector locations and pin orientation.

4 Installation
4.1 Power Supply
A clean DC power supply of 5V ± 5% 3A is required to power the A104B. The rise time of the supply
must be short enough to give a valid reset signal to the controller chip. It is recommended that the
power supply for the controller circuits is separate from the supply to the mechanism motor and solenoid
circuits, to minimise interference. In the event that the power supply is not adequate to power the
A104B, on board circuitry will hold the printer in reset and avoid any damage which may occur to the
printer mechanism.
4.2 Parallel and Serial Interface Selection
Serial and parallel data modes are selected using D7 (pin 1 on J3):
Parallel mode is selected if D7 is held low (connected to 0V) for a period of 100ms after the
printer is reset.
Serial mode is selected if D7 is held high or left unconnected (internal pull-up to +5V) for a
period of 100ms after the printer is reset.
In “classic” mode, the parallel interface is selected by having D7 low (logic “0”) at power up. In some
parallel applications the port driving this pin may be indeterminate at power up and so an alternative
parallel select is provided (jumpers S5 / S6). If either of the two serial/parallel select pins are held to
ground on start up, then parallel mode is selected. Both pins must be left high to select serial data. In
order to change from serial to parallel, or from parallel to serial, the printer must be reset. Serial data
Baud rates are selected on D5 and D6 when the printer is in serial mode.
Serial data Baud rates:

Note that the combination for 9600 Baud was used to select 110 Baud in the A160B family of controller
boards.
In order to implement the baud rate the printer must be reset.
4.3 Jumpers
There are three jumpers on the A104B (refer to layout for position). Closing these jumpers will select the
following:
S1 / S2
S3 / S4
S5 / S6
Self test

4.4 EMC Compliance
As a component, the A104B is outside the scope of the EMC Directive and the user must take
responsibility for the compliance of the complete equipment or installation. Please refer to the EMC
disclaimer in the Appendix.
5 Operation and Programming
5.1 Mechanism selection
All the four-needle EPSON mini-printer mechanisms (M150, M160, M163, M164 and M170) are now
supported by a single A104B device. The A104B exercises the mechanism on the first power-up, and its
type is sensed by counting tacho pulses per head cycle. The result is stored in the EEPROM, and on
A104B Users’ Guide Page 4 of 11
subsequent power-ups the mechanism identity is read from there. If the EEPROM is not fitted, the chip
will carry out the mechanism selection test at every power-up.
N.B. If the mechanism is changed, the ESC,<125> command can be used to force re-detection.
A104B Users’ Guide Page 5 of 11
5.2 Parallel Data Mode
D7 to D0 are the data connections for parallel mode 8 bit data. If using one of the backwards
compatible 7 bit character sets (A160C family) D6 to D0 are the data connections. Positive true ASCII
codes are accepted at TTL or 5V CMOS levels. The data inputs are not latched and must be static
during the handshake sequence. The Data Strobe input times the incoming data transfer. When the
printer is not busy (the busy signal is low) the data must be held static on the data pins and the strobe
signal taken low until the busy signal goes high to acknowledge the data transfer. The data strobe must
then be taken high ready to transmit the next byte. Figure 5.1 shows typical connections to a PC
parallel port.

5.3 Serial Data Mode
The serial data input accepts a TTL or 5V CMOS positive true signal. The busy signal will be low when
the printer is ready to accept data. The A104B is not suitable for direct connection to a PC RS232
COM: port. (Please refer to ASL for a converter board, or alternatively Able Systems produce an Ap25S
which is the serial RS232 version of the Ap25 and is suitable for direct connection to a PC.) Figure 5.2
shows typical connections to a PC serial COM: port for the Ap25.

5.4 Busy Output Signal
The controller asserts the Busy output when the input buffer is one character away from being full. The
following character will, however, be loaded into the input buffer. This avoids any data being lost due to
the host not responding to the busy signal immediately (such as with a double-buffered UART in a PC).
5.5 Printing modes and data buffer
Character printing modes include graphics, inverted, double height and double width. Graphics mode is
cancelled at the end of every dot line, whereas the combinations of double height and width remain in
force until cancelled by a new command.
The A104B will print data before the ESCape code and then implement the new mode selection. The
data buffer accommodates 48 bytes, which can extend over many physical print lines, depending on the
mechanism in use and the data format; and new data can be entering the buffer as previous data are
being printed.
5.6 Character Printing
The A104B prints the characters from left to right. The characters fit into a 6 wide × 10 high matrix. The
standard letter is 5 wide × 7 high, this provides for a one dot space between each character, a dot line
for descenders and a dot line above and below each character line. The number of characters required
to fill a dot line varies according to the printer mechanism.

The ASCII characters 32 to 255 (32 to 127 if using a backwards compatible 7 bit character set) are in
the printable range. Any character below character 32 is ignored unless it is one of the control codes
(section 5.8).
5.7 Graphics Printing
The product is programmed to take advantage of the graphics printing capability of the mechanisms.
Graphics are received as the least significant 6 bits of each byte. The same number of graphics bytes
are required to terminate a line as the number of characters required to print a complete line. The
graphics mode is reset at the end of every dot line and hence the graphics command, <ESC><02>,
must be entered at the start of every dot line. Graphics patterns are built up as a succession of dot
lines across the paper. Large areas of solid dots are not recommended as they may cause over heating
and shorten the ribbon life. Heavy graphics printing may also require a higher current power supply.
A typical graphics line for the A104B would be:
Control code Data (24 bytes for the M-160 printer mechanism)
<ESC><02>
<00><00><01><02><03><04><05> etc.
A104B Users’ Guide Page 7 of 11
5.8 Control Codes
9 character sets which may be selected for backwards compatibility. The default character set is the 8
bit IBM 224-character set.
Previous versions of the A160B family have been supplied programmed with 7 bit character sets, UK,
French, German, “Scandinavian”, Danish/Norwegian, Swedish, Japanese and Spanish character
variations (often to special order). The A104B contains all these variants, which may be software
selected for backwards compatibility. 8 bit data is selected when using the 8 bit IBM character set,
otherwise the 8th data bit is ignored.
The structure of the command is as follows:
<ESC><127><n> where n is a byte of the form [X,X,X,X,B3,B2,B1,B0] (X = don’t care)

The command <ESC><126> stores the current character set and print mode (double height, etc.) in the
EEPROM and these will be the default setting the next time the printer is powered on or reset. If this
code is not received the A104B reverts to previous default values on the next power up.

<LF><CR>
Print any buffer contents (line terminator). Treat as single <CR><LF>.
A character line is automatically terminated and printed if it reaches the full line width for a given
mechanism and print mode setting. Note that if any of the above 4 line terminator codes is received
immediately after a character which completes a printable line, it will be ignored.
This treatment differs from the A160B family but will generally be an improvement.
<VTAB>
Print any buffer contents, and feed 30 dot lines.
If the print quality deteriorates due to dot lines being displaced, the EEPROM can be cleared and the
chip forced to repeat the first-time initialisation by sending the code <ESC><125>.

To assist OEM customers, we have carried out traceable pre-compliance tests on our most popular
Ap24 printer, which indicate that the printer itself is unlikely to prevent EMC compliance of the
customer's equipment, as follows:
Since the A104B is DC powered and will only be electrically connected within an OEM equipment,
conducted emissions and immunity are not relevant, and we consider that the A104B falls outside
the scope of the Regulations in these regards.
When fitted in an earthed steel case and connected to an internal data source and power supply,
the A104B may be expected to comply with the requirements of the EMC Directive in respect of
radiated emissions and immunity;
When fitted with an earthing wire to the mechanism, the A104B may also be expected to comply
with the requirements in respect of electrostatic discharge (ESD).
