Applications
The Olivetti PR 4 is a compact, 3-station impact printer. It may be used at points of sale, in
hospitals and restaurants to:
- issue a receipt (ordinary or fiscal)
- print on a tally roll journal
- print invoices
- MICR reading/fill in cheques
It can print at various character pitches ranging from 12.5 to 16.6 CPI.
The receipt release station is provided with an automatic cutter, while the journal printing
station has an automatic rewinder.
The slip of paper is inserted from the bottom and fed automatically from this point.
The paper rolls may be various lengths and the paper loading procedure is fully automatic.
A cheque code line can be read by the printer equipped with the MICR reader option.
Cheques can also be drawn up with a 90 degree rotation of printing.
The customer display and cash drawer may be controlled directly by the printer firmware.
Software compatibility: TM 950, TM-U950 and TM-U950P Epson emulation.
Options
The printer may be provided with the following options:
a. External power supply
b. Internal power supply
c. Display and drawer driver

Modules
The printer is made up by the following main modules:
- printing module
- double roll module
- documents and cheques module
Printing module
The PR 4 prints using a dot matrix, impact print-head. A step motor advances the head along
the printing line with a resolution of 1/75".
Printing is bi-directional, with print path optimization.
The distance between the print head and the print contrast plate is automatically adapted to
the paper thickness by means of a spring mechanism.

Cutter life ranges from 250 to 350 thousand cuts.
Important: for longer life, the cutter must be maintained clean and free of all paper shreds.
MICR reader
With the MICR reader option installed, the printer can read the CMC7 or E13B magnetic
characters of cheque code lines.
Legible cheques must be conforming to ISO recommendations 2033-1983.
