GENERAL FEATURES
The FT190 is a printer which, in addition to having an innovative design,
guarantees high performance and is reliable and user-friendly.
For these reasons, it is the ideal solution for applications which require the
immediate printing of data on a ticket, whether they be of an industrial,
professional or laboratory nature. Typical fields of application are: weighing
systems, receipts (not for tax purposes) as well as for security, controlling
and diagnostics purposes.
It has a 200 dpi thermal print mechanism and uses 57.5mm paper rolls. It
can print 24 or 40 characters per line according to the selection made at the
setup stage through the software command.
The FT190 printer is so compact and lightweight that it can be installed
extremely easily on any type of equipment. It is supplied with TTL serial and
parallel interfaces and has a 1Kbyte reception buffer. It can also be
equipped with a Real Time Clock.
(Figure 1)

INTRODUCTION
FT190 4
DESCRIPTION OF THE PRINTER
The FT190 printer has an ABS casing (1) with a front cover (2) which opens
to allow access to the paper roll and print head.
The control panel is located on the front (3) and has a PRINT key, a FEED
key and two LEDs: Power and Status.
•PRINT key. When enabled it outputs, in parallel, the logic state “0” on
pin 4 of J1, while in serial it brings about the transmission of the control
character “$0D”, if this has been enabled at the printer setup stage. In
parallel on PRINT key there is a connector J6 used for the connection
to outside key (figure 1.1).
•FEED key. When this is pressed, the paper feeds forward manually. If
this key is pressed briefly, when the RTCK option is installed, the date
and time of day is printed.
•The POWER LED indicates that the the printer is receiving a digital
power supply.
•The STATUS LED, when flashing, signals that the paper is finished.
When lit steadily, it signals the presence of an error (head power supply
too high or too low or head temperature too high).
(Figure 2)

1. INSTALLATION AND USE
FT19011-
1.1 CONNECTIONS
1.1.1 Power supply
The FT190 printer is equipped with a standard 4-pin male AMPMODU1-type
connector (J7). The signals on the connector pins are as follows:
WARNING
Respect the polarity of the power supply.
It is possible to avoid connection with the feed connector (J7) by using the
logic circuitry’s flat 26-pin connector (J1) on request at the time of ordering,
thus connecting the printer’s power supply and signals with a single cable. In
this case, however, the flat cable must not exceed 30 cm in length because,
when electrical current runs inside small diameter wires, voltage failures can
occur, thus interfering with the correct operation of the printer.
For the pin pattern relative to feeding through the logic’s flat connector,
please refer to the following paragraph.

*The D7 signal is not taken into consideration in the event of 7-bit
programming of the parallel port. In order to configure the FT190 with the
extended character set, the parallel interface must be 8-bit programmed.
The signals indicated have the following functions:
GND: signal and power supply ground;
+VT: head power supply;
+VDC: logic card power supply;
PSE (input): serial/parallel interface selection. If shortcircuited to ground (0)
it enables serial communication; if free (1) it enables parallel reception;
D0, ..., D7 (inputs): data buses. In the parallel configuration, these
correspond to the printer input data bus (the high level indicates binary digit
1). In serial communication, if the serial parameter selection has been
chosen through the connector, these are used to determine communication
speed and reception protocol. Normally, the data bus is on logical level 1: to
obtain logical level 0, shortcircuit to ground (GND).
(Table 1.3)

1. INSTALLATION AND USE
FT190 41-
The serial baud rate is settable as shown in the table below:
D0 D1 D2 BAUD
001300
101600
1 1 1 1200
0 1 1 2400
0 0 0 4800
1 0 0 9600
All other combinations select the speed at 1200 baud.
D3 = 1: flag type transmission protocol. When the print buffer is full, the
printer sends a low level on the RTS signal, which interrupts transmission;
when the buffer is able to receive more data, the level of the RTS signal
changes to 1.
D3 = 0: XON/XOFF type transmission protocol. When the print buffer is full,
the printer sends a XOFF $13 (DC3) command, which interrupts
transmission; when the buffer is able to receive more data, the command
XON $11 (DC1) signal is transmitted.
D5, D6, D7: the selection of these bits causes the configuration of the serial
with the transmission format listed in the table below:
D7 D6 D5 Format
1 1 1 8 parity none bits and 1 stop bit
0 1 1 8 parity EVEN bits and 1 stop bit
0 1 0 8 parity ODD bits and 1 stop bit
1 1 0 7 parity none bits and 1 stop bit
1 0 1 7 parity EVEN bits and 1 stop bit
1 0 0 7 parity ODD bits and 1 stop bit
Remember that in order to configure the printer in serial mode, the signal
PSE must be shortcircuited to ground on connector J1.
RESET (input): reset card controller, active at low level. The reset initializes
the printer parameters, with the following effects:
• the line buffer and print buffer are erased;
• the print format is selected according to programming;
(Table 1.4)
(Table 1.5)

1. INSTALLATION AND USE
FT19051-
• the PSE pin of J1 is read for serial or parallel configuration;
• the autotest is printed, on pressing the FEED key;
• the functioning of any optional cards installed is checked.
READY/RTS (output): in the parallel configuration the high level indicates that
the printer is ready to receive data. A low level indicates that the printer is
busy. In serial communication, the high logic state (1) indicates that the
printer is ready to receive data; the low logic state (0) indicates that the print
buffer is full and cannot accept data.
FEED (input and output): paper feed key, active at low level. This signal is in
parallel to the contacts of the FEED key on the front of the printer.
STB/RD (input): in the parallel configuration, a low level indicates to the
printer that there is valid data on the data buses (D0, ..., D7). In the serial
configuration, it corresponds to the data reception pin.
TP (input and output): PRINT key, active at low level. This signal is in parallel
to the contacts of the PRINT key on the front of the printer.
1.1.3 Outside Print key
To the connector J6 (figure 1.1) can be related an outside Print key. The
polarity and the signal's function are as follows (table no. 1.6):

1. INSTALLATION AND USE
FT190 61-
1.2 CONFIGURATION
The FT190 enables the configuration of the printer default parameters.This
procedure is enabled by holding down the PRINT and FEED keys while
switching on, with the jumper JP2 present on the printer card open.
After this, each time the PRINT key is pressed, the parameter is modified
and its current value is printed. Once the required value has been obtained,
press the FEED key to proceed to the next parameter, and so on. Once all
the parameters have been run through, the printing of a message signals the
end of the setting procedure.
The parameters affected during configuration are:
• Selection of the number of columns (24 or 40)
• Print direction (normal or reverse)
• Selection of the character dimensions (normal, double width, double
height, expanded)
• Selection of the font (font 1 or font 2)
• Enabling or disabling of the CR command
• AUTOFEED enabling or disabling : if the function is enabled when the
printer receives a characters number equal to the line buffer the next
character will place on the left margin in a new line
• Selection of the print speed in function of the absorption
• Selection of the red intensity : using two-colour thermal paper is
possible to set different red tonality
• Selection of the parameters for serial and parallel communication
• Enabling or disabling of the 1Kbyte buffer
• Enabling setting of the real time clock
• Enabling of seconds printing in the real time clock function.
The settings made are saved on the EEPROM (non volatile memory).
1.3 AUTOTEST
To run the autotest, hold down the FEED key, while switching on the printer.
The autotest causes the printing of the printer’s current setting data and the
printing of the complete ASCII character set.

1. INSTALLATION AND USE
FT19071-
1.4 HEXADECIMAL DUMP
If the PRINT key is held down during switching on, the printer enters
Hexadecimal Dump mode. This function is used for the diagnostics of
characters received in serial or parallel. In fact, these are printed in
hexademical code together with the corresponding Ascii code.
1.5 MAINTENANCE
1.5.1 Changing the paper roll
To change the paper roll, proceed as follows:
1) Open the printer cover and press down the swinging support of the print
mechanism at the point marked PUSH;
2) Insert the end of the paper roll in the slit of the print mechanism and
position the paper roll so that it rotates in the right direction, as shown in
the figure;
3) The paper is automatically pulled by the roller for 3 or 4 centimetres;
4) Tear off the paper and re-close the cover.
WARNING
Before inserting the paper, ensure
that it is cut evenly
