GENERAL INFORMATION REGARDING SAFETY

•Read and keep the following instructions.

•Observe all warnings and follow all instructions attached to the printer.

•Before cleaning the printer, disconnect the feed cable.

•Clean the printer with a damp cloth. Do not use liquid or spray products.

•Do not operate the printer near to water.

•Do not place the printer on unsteady surfaces. It could fall and get seriously

damaged.

•Use the type of electricity supply marked on the printer label. In the event of

uncertainty, contact the seller.

•Position the printer in such a way as to ensure that the cables connected to it will

not be damaged.

maximum acceptable current for the type of feed cable used.

•Do not put objects of any kind inside the printer as they could cause a short circuit

or damage parts which could affect its performance.

•Do not spill liquids on the printer.

•Do not carry out technical operations on the printer with the exception of the

scheduled maintenance operations specifically indicated in the user’s manual.

•Disconnect the printer from the electricity supply and have it repaired by a

specialized technician should any of the following conditions occur:

1.1 GENERAL FEATURES

TheP190 (fig.1) is anextremely simpleand functionalwall printer. It isthe idealsolution forapplications

which require the immediate printing of data on a ticket, whether they be of an industrial, professional or

laboratory nature. It is suitable for POS, weighing systems, receipts (not for tax purposes), as well as

for security, controlling and diagnostics purposes.

It has an 8-needle, rapid impact printing mechanism and uses 57.5 mm wide paper rolls.

The P 190 printer is so light-weight and compact that it can be easily fitted on any kind of machinery.

It can be personally programmed and is thus able to meet all possible requirements. It has a 150 byte

print buffer and, as an option, can be equipped with a 2 Kbyte EEPROM. It has TTL serial and parallel

interfaces as standard or RS232 serial and CENTRONICS parallel interfaces as an option. It can, in

addition, be equipped with a Real Time Clock .

It comes in three colours and two models, with 24 and 40 columns.

1.2 PRODUCT DESCRIPTION

The P 190 printer has an ABS casing with a top covering the paper roll and print head.

The dimensions of the printer are shown in Figure 2.

The keyboard, located on the front of the printer, consists of the PRINT and FEED keys with their

respective LEDs.

FIGURE 2

• PRINT key. When this key is pressed, if the printer is in parallel pin 2 of J7 comes out of logic state “0”,

while in serial it transmits control character “$0D”; this only happens if it has been enabled by DATA4 to

logic “0” or if switch 5 of the RS232 option is in the ON position. The PRINT key LED only lights up

during printing. If the printer has a 2 Kbyte EEPROM (option, see paragraph 2.4), the contents of the

memorized blocks are trasmitted.

• FEED key. This enables the manual paper feed. If pressed briefly, when the RTCK option is installed,

the time and date are printed. When the FEED key LED lights up, it is to indicate that the logic card

power supply is correct, i.e. that it is over 3.7 V (minimum threshold below which the printer is reset and

the LED goes out).

2.1 REMOVING THE PRINTER FROM ITS PACKAGING

Open the package and check that:

a) none of the parts have been damaged during transportation;

b) that the ink cartridge is fitted on the printing mechanism and the paper roll is in place;

c) the two brass screws and washers necessary for installing the printer are, in fact fitted on it

FIGURE 3

2.2 INSTALLATION PROCEDURE

Make a 112 mm x 112 mm square hole in the wall where the printer is to be installed (see Figure 3).

Unscrew the two brass washers “A”, leaving the screws “B” in their holes. Insert the printer into the hole

on the wall, open the front panel and, from the back, manually screw in the two brass washers, until the

printer is firmly in place.

Insert the interface and the power supply connectors, located on the logic card.

If possible, protect the machine from direct light sources.

2.3 CONNECTIONS

Power supply

Withregardtopower supply,theP190 printerhasastandardAMPMODU1 4-pinmale(J3)typeconnector.

The power supply connector pins are marked as follows:

1 GND

2 GND

3 +VT: 5 Vcc ± 15% (printer needle power supply)

4 +VCC: 5 Vcc ± 7% (logic card power supply)

Connecting with the power supply connector (J5) can be avoided by using the flat 20-pin connector (J1)

of the logic or by replacing the latter, by special request at the order stage, with a similar 26-pin one,

thus connecting the power supply and the printer signals with a single cable. In this case, however, the

maximum length of the flat cable must not exceed 30 cm for the 20-pin version and 70 cm for the 26-pin

version. The reason for this is that current running along inside narrow wires can lead to power failures

which could interfere with the correct functioning of the printer.

Ifthe printerhas the RS232or CENTRONICSoptions, itmust besupplied by meansof theJ5 connector.

For the pin pattern required for supplying power through the logic flat cable, please refer to the following

paragraph.
