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).
