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.
•Ensure that the maximum absorbed current of the printer does not exceed the
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:
A. The feed connector has been damaged;
B. LIQUID has penetrated to the inside of the printer;
C. The printer has been exposed to rain or water;

1.1 General features
The P150 (figure 1) is an extremely simple and functional panel printer. It is the ideal solution for
applications which require the immediate printing of data on a ticket, whether they be of an industrial,
professionalorlaboratory nature.Itis suitable forPOS, weighing systems,receipts (not fortax 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 150 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. It has TTL serial and parallel interfaces as standard or RS232 serial and CENTRONICS
parallel interfaces as options. It can, in addition, be equipped with a Real Time Clock . It comes in three
colours and two models, with 24 and 42 columns.

1.2 Product description
The P 150 printer (figure1) has an ABS casing with a top covering the paper roll and print head.
The dimensions of the printer are shown in Figure 1.
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.
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
1. 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.
2. 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.
3. Insert the interface and the power supply connectors, located on the logic card.
