1 GENERAL INFORMATION
1.1 PRINTER OPERATION
The basic idea for the conception of the MTH-2500 printer, was to push
miniaturization as far as possible. The whole printer: case - head - interface
holds in the volume of a big matchbox and consists of very robust elements.
Small size also implies a small dimension for the paper roll, and also the
change of paper was optimized to be extremely simple: you just need to
open the upper lid, insert the paper roll and push the lid back to its initial
position.
Could it be more simple?
MTH-3500 printer as the same basis with a greater paper case (Ø 60 mm).
Thanks to this greater size, this printer can use labels rolls.
Numerous features are enclosed in the management software of the printer
allowing for the printing of graphs and bar codes as well as numerous special
effects.
Bonus:
ü A 8K-bytes logo can be stored in the flash memory. The printing of this
logo can be made through the printer interface or by closing a separate
dry contact.
ü Two character sets are embarked to allow you to vary your printed tickets.
ü A very simple to implement graphic mode allows you to realize nice
curves without complicated calculation.
ü Windows 10, 8.1, 8, Seven, Vista, XP, 2K drivers are available and can be
downloaded from our web site. This driver uses graphic compression tiff4
to increase the printing speed. It allows to select printing between paper
or labels rolls. These drivers are unsigned , please disable the protection
of drivers signed under the recent Windows to allow installation.
The printing speed and the silence of operation makes it the ideal instrument
for point of sale terminals, ticket machines, cash registers and medical
applications.
The 203 dpi density ( 8 points/mm ) authorizes the printing of graphs, curves
and bar codes with excellent quality and resolution.

1.2 MATERIAL DESCRIPTION
The printer is designed around a Microchip PIC18F67J50 microprocessor,
128K-bytes of flash ROM and 3904 Bytes of RAM (2k-bytes are reserved for
the receive buffer). An internal watchdog in the microprocessor is activated to
insure an operation in strongly polluted industrial environment.
The printer can be connected in serial in TTL or RS232C levels, RS422
(without protocol or Modbus over serial), in USB 2.0, in Ethernet
(Raw TCP/IP) ou (ModBus over TCP) or in parallel. Characters received by
the interface are stored in its memory and interpreted by the micro-processor.
Different features such as line-feed and menu buttons, control LED, paperend detector and rewinder are directly driven by the MTH-2500, MTH-2700 or
MTH-3500 printers.

3 PRINTER OPERATION
3.1 START-UP
1. Connect the power supply and connection cables
2. Turn power on
The interface will control its memory, set its parameters according to the data
menu stored in its Flash memory, look for the possible presence of a clock
circuit and moves the printing head 8 steps to synchronize the step motor. At
the end of this initialization cycle, the printer is ready for receiving characters.
3.2 SYSTEM REINITIALIZATION (RESET)
The printer is designed with a watchdog which makes a reset at power-up
authorizing the use of a slow ascent supply. About 300 milli-seconds after the
controller is powered-up, this one is ready for operation, having ended its
reset cycle.
3.3 PAPER LOADING
• Open the printer
• Remove the old
paper roll
• Install the new
paper roll
• Close the printer
3.4 CONTROL PANEL
The control panel allows the user to interact with the printer with two
pushbuttons and a status light.
• Button ► is used to feed the paper, to do the self-test of the printer, to
activate the hex dump mode (§ 3.5) and for the setup menu (§ 5.5).
• Button ■ is used for the setup menu (§ 5.5).
• The bicolour LED informs the user of any malfunctions. A continuous
GREEN light indicates proper operation, a flashing RED light informs an
anomaly whose description is detailed in the table in § 5.6.
11 MTH-2500, 2700 & 3500 v3.4
Page 12
3.5 SELF TEST OR HEXADECIMAL DUMP
If, after a reset, the linefeed button ► is
maintained pushed, a special cycle is run.
The printer starts by printing the 4 first lines
of the self test then wait until the button ► is
released.
Selftest :
Simply release the button ► without other
actions, the printer goes into self-test cycle.
Printer parameters and character set ate
printed. The selftest gives only a probability
of correct operation of the printer; indeed, the
selftest procedure does not use transmission,
this one can only be tested in real mode.
Then connect interface and power supply.
The printer is ready for use !
Here is an example
of partial selftest→
Hexadecimal Dump:
Depressed the button ■ before releasing the
button ►, the printer will switch to hexadecimal dump mode. It will print the
text "HEX DUMP:”
In this mode, the hexadecimal values of
successive characters are printed in a first
column and their ASCII shapes in a second
column. Warning: the control codes are not
interpreted any more. This mode is used for
connection debugging. Each line begins by a
characters counter (also in hexadecimal).
A hexadecimal dump is implemented in the
printer. This mode can be activated for a long
time by setting the setup menu :
Advanced->Compatible on HEXA.

4.2 PRINTER LANGUAGE OR COMPATIBILITY
MTH: The default printer language is called MTH. It is near ESC/P commands
essentially in text printing. In graphic, only one horizontal dot line is printed at
once while ESC/P mode uses 8 or 24 vertical dot lines.
PCL: Last mode is PCL Raw. Only the graphic raw modes are interpreted
with several compression types : No compression, Run Length, Tiff and Delta
Row. A graphical scaling mode is implemented to fit large graphic printouts in
the width of the printer.
EPS24 Lite: This mode is reserved to special applications.
It is not a full Epson 24 needles compatibility.
Hexa: In this mode, the hexadecimal values of successive characters are
printed in a first column and their ASCII shapes in a second column. Warning:
the control codes are not interpreted any more. This mode is used for
connection debugging. Each line begins by a characters counter (also in
hexadecimal). This mode can be temporary activated at the power-up (see
chapter 3.5).

Printing graphic curves.
This command allows for easy printing of curves along the paper
(vertically). The m value (transmitted on 2 bytes) represents the number of
curves (points) to be printed for the current graphic line, and must be
included between 1 and the maximum number of printable points per line
(384).
The n1 .. nm values represent the position of these m curves (or points); the
number of points (n1 .. nm) must be equal to m.
Each point must be included between 1 and the maximum number of
printable points per line (384), otherwise it will not be printed. As horizontal
lines printing progresses, the vertical curves will show on the paper.
The vertical lengthening (ESC 'w' n) act on the graphic curves.
Example: Basic software to print 4 curves and a central axis.

This command must be ended by the FF Hex
= 255 Dec character.
Remark: If the chain contains a non authorized
character or if the resulting bar code exceeds
the paper width, the bar code drawing is replaced by a simple grey pattern
and the erroneous character is replaced by a '?' in the HRI characters.
Example in CODE 39: ESC " 0 MEGATRON
so in hex: 1B 22 30 4D 45 47 41 54 52 4F 4E FF
· ESC " 1 n (1B 22 01 n Hex = 27 34 1 n Dec)

6 (06H) CODABAR 0 to 9, A,B,C,D,E,N,T,$,+,-,=,/,.
Example: Setting CODE 39 ESC " 1 4
so in hex: 1B 22 31 34 or 1B 22 01 04
· ESC " 2 n (1B 22 02 n Hex = 27 34 2 n Dec)
Enlargement factor of the bar code where n+1 represents the enlargement
factor ( n between 0 and 3). The default value of n is 0.
Example: Set Enlargement to 1 ESC " 2 1
so in hex: 1B 22 32 31 or 1B 22 02 01
· ESC " 3 n (1B 22 03 n Hex = 27 34 3 n Dec
Height of the bar code where n represents the
number of dot lines of the bar code.
The default value for the height is 48,
therefore 48 * 0.25 mm = 12 mm.
All the n values included between 1 and 255 are available.
Example: Set height to 60 lines ESC " 3 <
so in hex: 1B 22 33 3C or 1B 22 03 3C

4.3.9 VARIOUS COMMANDS
· CAN (18 Hex = 24 Hex)
Cancelling the printing of previous characters.
· ESC @ (1B 40 Hex = 27 64 Dec)
Software reboot.
All the settings are re-set to their default value.
· GS v n (1D 76 Hex = 29 118 Dec) ou
ESC v n (1B 76 Hex = 27 118 Dec)
Printer interrogation on serial interface.
When receiving this sequence, the printer
sends a parameter corresponding to the n
value back on the serial interface.
No effect in parallel or USB interface.
· ESC = n (1B 3D Hex = 27 61 Dec)
Regrouping / Degrouping the strobes.
n = 1 (01 Hex) or '1' (31 Hex)
Regrouping the strobes
n = 0 (00 Hex) or '0' (30 Hex) Degrouping the strobes
Default value is set by the setup menu.
Degrouping the strobes: to reduce the average power consumption of
the printer, by default, the 6 strobes driving the printing head are
successively driven one after the other. While printing text, the average
power consumption is reduced to the detriment of the printing speed.
Grouping the strobes: to increase the printing speed, several command
strobes of the printing head can be grouped without exceeding the printers
capability. Caution: the power consumption is then at the maximum level.
· GS <FD> <zone> <Low> <High> <datas> (1D FD Hex=29 253 Dec) ou

4.4 PCL RAW COMMAND
PCL Raw compatibility is implemented to allow connections on computers or
terminals where installing new drivers is not possible and PCL is embedded.
Only the graphic functions are optimized in this mode.
Other PCL commands are ignored.
Graphical compressions Run Length, Tiff and Delta Row are supported.
Mnenomics Hexa PCL commands implemented
ESC "&" 1B 26
ESC "&" "a" # "H" Horizontal position
ESC "*" 1B 2A
ESC "*" "b" # "W" Graphic print
ESC "*" "b" # "M" Select graphic compression
(No compression, Run Length, Tiff, Delta Row)
ESC "*" "r" # "T" Set page length
ESC "*" "p" # "X" Set horizontal position
ESC "*" "p" # "Y" Set vertical position
ESC "E" 1B 45 Software reset
PCL commands ignored : ESC "!" ESC "#" ESC "$"
ESC "%" ESC "(" ESC ")" ESC "+" ESC "/" ESC "."
Remarque: Les autres commandes du mode Megatron qui n'ont pas
d'équivalent PCL peuvent toujours être utilisées.
A graphical scale mode is implemented in the printer.
• For horizontal scale, set "Advanced" -> "Horz Scale" menu.
Scale factor is calculated on one byte, i.e. on 8 consecutive columns
of the transmitted graphic.
All the graphic line is analysed 8 columns at a time.
Example:
• to print 1 column on 2,
set "Horz Scale" to "Scale 50%"
• to print 1 column on 4,
set "Horz Scale" to "Scale 25%".
• For vertical scale, set "Advanced" -> " Vert Scale" menu. It works
like horizontal scale but on 8 consecutive lines of the transmitted
graphic. Generally, it is used to keep the Ratio Horizontal/Vertical.
• Limiting the number of blank lines in PCL. The number of the setup
menu "Advanced"-> "Blank PCL #" limits the amount of consecutive
empty dotlines points to this value (0 to disable).

Page 28
4.5 LABELS
Label mode is available only with MTH-3500 printer because its paper roll
diameter is bigger. It is enable by setting menu Printer -> Label Use on
Enabled.
This mode change the printer operating :
● Paper-end optical sensor is used to detect the holes between the
labels. The maximal hole height is 10 mm. A hole greater than 11 mm
is interpreted as a Paper End.
● Depress on LF button feeds the label roll to the start of the next label.
● Form feed command (0Ch) feeds the label roll to the start of a label.
Page length parameter is not used in this mode. Other commands are
explained in chapter 4.3.7
● If no hole is detected during a too long length of paper, an error is
sent to the user with the LED. May be, it is not a label roll but a paper
roll or the paper-end optical sensor is defect.
Note: The printer mechanism doesn't allow to use black marks, labels rolls
must use holes between the labels. The begin of the hole is used to detect the
start of a label.
Some parameters have to be set in the Printer menu to allow a good
detection of the labels :
Label Use : Printer uses the label mode or not
Label Gap : Inter-labels spaces, between 16 and 255
(mini recommended 64)
Label Hi: High part of the Label height, between 0 and 3
Label Lo: Low part of the Label height, between 0 and 255
Label Hole: Spaces between the end of a label and the start of the hole,
between 0 and 56
Remember: All distances are in dot lines,
i.e.: distance in mm / 0.125.
MTH-2500, 2700 & 3500 v3.4 28

Labels rolls details
Holes: The holes must be
● Centred at 13.5 mm of the right paper edge.
● Minimum 3 mm width
● Height between 2 and 10 mm. To recognize a paper-end of a hole,
holes must have a height <11mm i.e.: <88 dot lines (88 x 0.125mm).
● Margin E ('Label Hole') between label end and the start of a hole can
be set (between 0 and 56 dot lines, i.e. between 0 and 7 mm)
Inter-Labels Spaces G or 'Label Gap':
● Height between 2 and 31,8 mm. Suggested >= 8 mm.
● Feed back is not recommended. To immediately unglue the last
printed label, we recommend a 8 mm minimum of inter-Labels spaces
G ('Label Gap') even if the actual distance is smaller; but you lose
some part of the top of the next label
Labels:
● Height H between 7 and 127.8 mm ('Label Hi' *256 + 'Label Lo')
● Width 48 mm. If lower width, user must take care to not print out the
the useful area.
Roll:
● Labels support width: 57 mm ± 0,5 mm
● External diameter maxi 60 mm (for MTH-3500)
