USER’S MANUAL
INTRODUCTION
SYNERGY PF-550 is a compact thermal printer with fiscal memory, which prints cash receipts and daily reports
on two separate paper rolls 58 mm wide. It is compatible to most European and World fiscal legislation systems.
The functions of the device are controlled with the help of buttons, located on its frontal part as well as commands,
sent via the serial interface. The couplings for the cable connections are conveniently located for fast access and easy
manipulations. The printing devices have low noise emission levels and high printing speeds - 50 mm/sec.
The printer has an automatic paper cutter. Optionally, it can support a display and a cash drawer.
Contemporary commercial activities and the demands of acting fiscal legislation systems demand a comparatively
good knowledge on the ways to operate fiscal devices of different kinds - cash registers, electronic scales, different
types of printing devices. It is for this reason, that the careful reading of this manual before starting work with the
printer may save you lots of time and trouble later on.
WORKING WITH THE FP-550 FISCAL PRINTER
The over 50 different commands which the printer can execute may initially create the impression that learning to
work with it is a difficult job. Most of these commands, however, are related to the starting initialization, diagnostics
and the generating of reports thus decreasing greatly the number of commands directly engaged with the issuing of
receipts and other user’s operations.
As an example may serve the commands, which must be sent to the printer to make it generate a fiscal and a non-
fiscal receipt. Only the order numbers of the commands will be presented and the data there related without getting into
the details of the contents of the special symbols which guarantee the viability of the data and ensure the correct
communication between the printer and the personal computer.
