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 non­fiscal 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.

TAX CATEGORIES AND CALCULATION OF VAT

The commands for sale are accepting as parameters the big letters А, Б, В, Г (ASCII codes 192, 193, 194, 195).
Neto value is calculated by the formula:

net_amount = ROUND(sale_amount / (1 + tax_rate))

Payed tax is calculated by the formula:

tax_amount = sale_amount - net_amount

Important:
If the user of the fiscal printer is TAX payer (the VAT number is not empty) then TAX categories А, Б and В
are accepted, and Г is refused.
If the user of the fiscal printer is not TAX payer (the VAT number is empty) then TAX category Г is accepted,
and А, Б and В are refused.

DIFFERENCES TO PF500

- If the user of the fiscal printer is TAX payer (the VAT number is not empty) then TAX categories А, Б and

В are accepted, and Г is refused.

- If the user of the fiscal printer is not TAX payer (the VAT number is empty) then TAX category Г is

accepted, and А, Б and В are refused.

- Daily report can be executed only once in a day.

FISCAL RECEIPT

OPENING A FISCAL RECEIPT

Command: 48 (30h)
Data: “1,000000,12”

The first number is the operator’s number (maximum 16), the second is the operator’s password while the third is
the order number of the point of sale (department or location). In a newly purchased printer the six zeros are the
operator’s default password – you may, naturally, enter your own. The third number is suitable only in commercial
centers with many points of sale (departments). After entering this command the printer will print out several “header”
lines which will contain the text registration number and the name and individual number of the operator.

REGISTERING A SALE

Command: 49 (31h)
Data: “2 x 120 <TAB>B2.40”

A text of 25 symbols is printed /prior to the symbol there is a tab symbol - 09h/, the price of the item and its
relevant tax group, which is in the 40th position on the line. The commentary may be of only two lines, in which case
the lines will be divided with an <LF> (0Ah).

PAYMENT

Command: 53 (35h)
Data:”<TAB>P2.50”

The command is used for receiving the payment on the registered sales, after which new sales are forbidden. Before
the tab symbol the spacing might also have a descriptive text of one or two lines, which have not been presented in the
example. Symbol ‘P’ shows the type of payment employed - in this particular case “in cash” - after which the sum due
is printed out. The payment can be performed several times but the closing of the receipt is possible only if the overall,
paid sum is equal or greater than the sum of the sales.

CLOSING A FISCAL RECEIPT

Command: 56 (38h)
Data: “”

The command print a maximum of two lines of text - usually an advertisement “footer”- the reg. number of the
document, the quantity of the sales registered and the compulsory elements of any fiscal receipt: fiscal logo, date and
hour, serial number of the printer and the reg. number of the fiscal memory. After sending the command the paper is
cut, if automatic cutting is enabled. The printer is ready for a new document.

PROGRAM SUPPORT

To function normally the program for operating the fiscal printer must be able to control the execution of the
commands, which often fail mainly due to the lack of paper, the sending of invalid commands or simply because of
some minor cable problem. The current status of the printer is monitored by 6 bytes, returned by every command. Part
of the bits are informative /opened non-fiscal receipt for instance/, others indicate error /no paper, invalid command,
etc./. The program must inform of existing errors or - if possible - react to these errors.

There are commands with the help of which the control program can acquire the whole needed information on the
current status of the printer. The printer saves this info in the memory as well as the accumulated sums (during the day
or only within the current receipt) even after it has been switched of from the power feed. If the device is in the
“document opened” mode it cannot close down automatically but only from the control program.

GENERAL DESCRIPTION OF THE PF-550

The functional control of the printer is performed with the help of buttons, located on its frontal part and
commands, sent via the serial interface. The coupling of the cable connections are located in such a way as to make
them easily connectable and the whole device fast to set up for normal operation.

Prior to using this device please read these instructions and the descriptions of the application programs carefully
and make sure that you have really learned how to operate the PF-550 .

Fiscal Printer SYNERGY PF-550

CONTROL PANEL INDICATORS AND BUTTONS

“Power” indicator

Lights in green when the printer is on and does not execute commands. When the light is out this is an indication
that the printer is “engaged” with a command.

“Error” indicator

Activated continuously when there is no paper in the device and blinks at the overheating of one/both printing
devices. Goes out when the error is cleared.

“Cash receipts” button

Moves the cash receipts paper roll forward. When the button is kept pressed down while power on, the printer
generates and prints out diagnostic information on both paper rolls.

“Journal paper roll” button

Moves forward the electronic journal paper roll. When pressed down while power on prints out the daily report
without clear (X-report). This can be also generated through a separate command.

When both buttons are pressed down while power on, the printer generates a short periodic report for the whole
period of exploitation if (and when) the printer is a fiscal device. The job will also be done through a special command.

INTRODUCTION

The fiscal device operates under the control of an application program, with which it communicates via the RS232
serial connection. The device executes a previously set of wrapped commands, arranged according to the type of the
operations which have to be executed. The application program does not have a direct access to the resources of the
fiscal device although it can detect data connected with the status of the fiscal device and the fiscal memory.

The fiscal device performs the following types of operations:

 Saves the serial number of the fiscal device and the number of the fiscal memory;
 Saves fiscal parameters, like the tax registration number, the date of entering into exploitation, etc.;
 Saves information on the owner - name and address, etc.;
 Saves the daily turnover in the fiscal memory and generates a daily report;
 Generating reports on concluded sales and the content of the fiscal memory;
 Dispatching data to the application program.

TAXATION CATEGORIES AND CALCULATION OF VAT

Each concluded sale can be related to a certain taxation category (VAT) defining a tax rate, applicable to the base
price used for the formation of the sale price. The fiscal printer can operate with a maximum of 4 taxation categories,
which are most often indicated with the first letters of the language of the country, where the fiscal printer is used-in the
case of England these letters are A, B, C, D.

Each of the taxation groups has a set tax rate (in percent) which is expressed by a number not greater than 99.00
and by no more than two digits after the decimal point.

Part of the four standard categories may be forbidden by using Rates_fewer in the 83(53H) command. The
commands for registering sales read the said four letters as a parameter.

FUNCTION MODES OF THE FISCAL DEVICE

The fiscal device has two functional modes:

1. The tutorial mode. The device is not fiscalized and all data needed for its normal functioning are
entered and saved in the fiscal memory with the exception of the tax registration number of the owner. Fiscal
receipts can be opened and closed but they always bear the inscription that they are not fiscal. Daily financial
reports with clearing can be generated but they are not saved in the fiscal memory.

2. Normal mode. The device has been fiscalized and the tax registration number of the owner is saved in
the fiscal memory. Al fiscal rules apply.

Fiscal Printer SYNERGY PF-550

STATUS OF THE FISCAL DEVICE

The status of the fiscal device can differ. Shifting from one to another condition is not always possible. The control
of the printer and the shifting between the different functions - when this is possible - is executed by the application
program Host (PC), which must relate to the included protocol. If this protocol is not applied correctly the printer might
enter into an undesirable status or to skip a given functional status, leading to an ERROR.

A) INITIAL STATUS

This is the functional status in which the date and the hour are set, the number of the fiscal memory is entered as
well as the serial number and the code of the country where the device will be operated.

THE ABOVE-DESCRIBED OPERATIONS ARE PERFORMED PRIOR TO SELLING THE DEVICE TO
THE CLIENT ONLY BY AN AUTHORISED SERVICE SPECIALIST!

The following commands must be performed in the order in which they are presented: 61 (3DH) and 91 (5BH).

B) STATUS AFTER THE FORMATTING OF THE FISCAL MEMORY

This is the state in which the name of the currency is entered, the number of the digits after the decimal point and
the tax rates. After performing these operations the fiscal printer is ready for delivery to the future operator (owner).
This is also the status in which the device is kept in the warehouse of the manufacturer.

The following commands are performed in the order in which they are presented: 83 (53H) and 96 (60H).

C) STATUS WHEN PRESENTING THE DEVICE TO THE CLIENT

In this functional state the header and the footer are set - the beginning and the end of each receipt. The header
contains information on the owner (name of the company, address etc.) while the footer is usually a short advertisement
text.

The command 43 (2BH) is performed as many times as is the number of printed lines.

D) TUTORIAL MODE

The fiscal printer is in this status prior to fiscalization. Receipts can be issued but it must be born in mind that they
will bear the mark “non-fiscal”. The generation of a daily turnover report with clear but it will not be saved into the
fiscal memory. A tax registration number is also entered but not into the fiscal memory and is subject to change. The
clearing of the memory does not cause an entry in the fiscal memory. The clock may be set arbitrarily.

E) A FISCALIZED PRINTER

In this functional status fiscal receipts may be issued and they will be marked “fiscal”. The daily report and clear is
registered in the fiscal memory and the setting of the date is possible only ahead in relation to the last entry in the fiscal
memory. The tax registration number is registered in the FM and cannot be changed from this point on. It is
IMPOSSIBLE for the printer to exit the fiscal mode without changing the fiscal memory.

The tax registration number of the owner of the device must be known prior to fiscalization. Command 98 (62H)
after which the command 72 (48H) must be executed.

F) IRRECOVERABLE ERROR IN THE FISCAL PRINTER

This is the status of the printer when a serious technical or logical mistake has occurred as well as in case of fiscal
memory failure. After switching ON the device in this mode a bold sign “FATAL ERROR: 4” appears. The printer
does not perform commands for opening fiscal receipts as well as documents, which save data entries into the fiscal
memory. Only diagnostic commands and periodic reports can be executed. Clearing the RAM and placing a new fiscal
memory module must be performed because the module used before the error is now switched to the READ ONLY
mode. ALL THESE OPERATIONS MUST BE PERFORMED BY AN AUTHORIZED SERVICE SPECIALIST.

The events, which can bring the printer to this state, are:

- Impossibility to make a correct entry in the fiscal memory;

- Invalid control sum, tax number, serial number, reg. No. of the fiscal memory or some of the entries which

contain the tax rates.

- Unidentified format of the fiscal memory module;

- If during the fiscal memory check up (immediately after switch ON) more than three invalid control sums

from a daily report fiscal entry are found.

The current status of the device is coded in a field 6 bytes long which is sent within each message of the fiscal
printer. Description of each byte in this field:

Fiscal Printer SYNERGY PF-550

POWER SUPPLY CUT-OFF

The status of the printer at each particular moment is reflected in the so-called “status bytes”. The application
program must get information on the status of the printer when switched ON after a power cut-off. This is performed
by the commands 76 (4AH) and 103 (67H).

The application program must make a decision on the future behavior of the printer depending on its current status.
It is guaranteed that the fiscal memory will not be affected by the power failure as well as that all accumulated sums in
the operational memory of the device will be valid. If the power cut-off has occurred during a printing session, when
switched ON, again the printer will print a line containing the text “* POWER DROP *” in an expanded bold type and
will then complete the print.

If power has failed during the printing of a daily report, after switch ON, the device will print the message “PRINT

REPEAT” in an expanded bold type and will restart the execution of the command (i.e., printing will be resumed).

ISSUING FISCAL RECEIPTS

A fiscal receipt is first opened, the sales are registered, payment is performed and the receipt is finally closed.

The following commands are used: 48 (30H), 49 (31H), 51 (33H), 52 (34H), 53 (35H), 54 (36H) and 56 (38H). At
the end of the day a daily financial report and clear are performed in order to enter and save the accumulated
information in the fiscal memory. The function is started with the command 69 (45H).

GENERATING REPORTS

Reports are generated singularly by the fiscal printer upon receiving the respective command from the PC. In these
reports the user’s program will not add any changes to the appearance and content of the reports, i.e., they appear
exactly as they have been defined in the fiscal printer. The following commands are used for the generation of reports:

50 (32H) Report on changes in tax rates and decimal points

69 (45H) Daily financial report with or without clear

79 (4FH) / 95 (5FH) Short financial report from date to date /from number to number of the respective fiscal

entries

LOW LEVEL PROTOCOL

A) PROTOCOL TYPE - MASTER (HOST) / SLAVE

The fiscal printer performs the commands sent by the Host and returns messages, which depend on the result.

The fiscal printer cannot instigate asynchronous communications itself. Only responses to commands from the Host
are sent to the Host. These messages are either wrapped or single byte control codes. The fiscal printer maintains the
communication via the RS232 serial connection at baud rates of 19200 and 9600 b/s, 8N1. The baud rate is set by
adjusting the configuration switch SW4.

B) NON-WRAPPED MESSAGES - TIME-OUT

When the transmitting of messages from the Host is normal, Slave answers not later than 60 ms either with a
wrapped message or with a 1 byte code. Host must have 500 ms of time-out for receiving a message from Slave. If
there is no message during this period of time the Host will transmit the message again with the same sequence number
and the same command. After several unsuccessful attempts Host must indicate that there is either no connection to the
fiscal printer or there is a hardware fault.

Non-wrapped messages consist of one byte and they are:

A) NAK 15H

This code is sent by Slave when an error in the control sum or the form of the received message is found. When
Host receives a NAK it must again send a message with the same sequence number.

B) SYN 16H

This code is sent by Slave upon receiving a command which needs longer processing time. SYN is sent every 60
ms until the wrapped message is not ready for transmitting.

C) WRAPPED MESSAGES

a) Host to printer (Send)

<01><LEN><SEQ><CMD><DATA><05><BCC><03>

b) Printer to Host (Receive)

<01><LEN><SEQ><CMD><DATA><04><STATUS><05><BCC><03>

Fiscal Printer SYNERGY PF-550

Where:

<01> Preamble.

1 byte long. Value: 01H.

<LEN> Number of bytes from <01> preamble (excluded) to <05> (included) plus the fixed offset of 20H.

Length: 1 byte. Value: 20H - 7FH.

<SEQ> Sequence number of the frame.

Length : 1 byte. Value: 20H – FFH.
The fiscal printer saves the same <SEQ> in the return message. If the FP gets a message with the
same <SEQ> as the last message received it will not perform any operation, but will repeat the last
sent message.

<CMD> The code of the command.

Length: 1 byte. Value: 20H - 7FH.
The fiscal printer saves the same <CMD> in the return message. If the printer receives a non­existing code it returns a wrapped message with zero length in the data field and sets the respective
status bit.

<DATA> Data.

Length: 0-91 bytes for Host to printer, 0-84 bytes for Printer to Host. Value: 20H – FFH.
The format and length of the field for storing data depends on the command. If the command has no
data the length of this field is zero. If there is a syntax error the respective status bit is established in
the data and a wrapped message is returned with zero field length.

<04> Separator (only for printer-to-Host massages)

Length: 1 byte. Value: 04H.

<STATUS> The field with the current status of the fiscal device.

Length: 6 bytes. Value: 80H-FFH.

<05> Postamble

Length: 1 byte. Value:05H.

<BCC> Control sum (0000H-FFFFH)

Length: 4 bytes. Value of each byte: 30H-3FH.
The sum includes between <01> preamble (excluded) to <05>. Each digit from the two bytes is sent
after 30H is added to it. For example the sum 1AE3H is presented as 31H, 3AH, 3EH, 33H.

<03> Terminator

Length: 1 byte. Value: 03H.

MESSAGE COMPOSITION, SYNTAX, AND MEANINGS

a) The data field depends on the command.

b) The parameters sent to the printer may be separated with a comma and/or may have a fixed length.

c) The comma between the parameters shows that it is mandatory.

d) When the parameters are closed by <> they are mandatory although the brackets themselves are not present in
the message. When a given parameter is closed in [ ] it is not mandatory - the bracket themselves are also not present in
the message. When parameters are separated by ‘|’ symbol, only one of them may present in the input data.

The symbols with ADCII codes under 32 (20H) have special meanings and their use is explained whenever
necessary. If such a symbol has to be sent for some reason (for example in an ESCAPE-command to the display) it
must be preceded by 16 (10H) with an added offset 40H.

Example: when we write 2500, 100, Text for the data field then in that field there will be 2D 32 35 30 2C 31 30 30
2C 54 65 78 74 where each hexadecimal digit is an ASCII value.

Fiscal Printer SYNERGY PF-550

DETAILED DESCRIPTION OF THE COMMANDS

21H (33) CLEARING THE DISPLAY

Data field: No data
Response: None

A clear display command is sent. If a fiscal receipt is opened and SW3 is OFF only the lower line is cleared.

23H (35) TEXT ON THE LOWER LINE OF THE DISPLAY

Data field: <Text>
Response: None

Text A text of up to 20 symbols sent directly to the display. Prior to this a command for positioning

and clearing the lower line is sent.

2CH (44) ADVANCING PAPER

Data field: [Lines[,Option]
Response: None

Lines Advancing paper measured in lines. The programmed line count cannot be greater than 99 (1 or 2

bytes). If the parameter is not there the default setting is 1 line.

Option Defines which paper to be advanced:

“0” No effect
“1” The receipt paper roll is advanced
“2” The journal paper roll is advanced
“3” Both paper rolls are advanced to the set length.

If the second parameter is missing the default setting is to advance only the receipt paper roll.

2DH (45) CUTTING OFF PRINTED DOCUMENTS

Data field: None
Response: Result

Result The result from the execution of the command:

“P” Successful cut off
“F” The automatic cutter has blocked.

The command causes the cutting off of the printed, ready document. It must be considered that the program must
advance the paper with at least two lines or the document will not be cut off correctly. If the printer is in the “automatic
cut off” mode it positions the paper itself and the command becomes redundant.

When the printing mechanism blocks for some reason, the paper roll must be taken out of the cutter mechanism and
the command must be executed again. This will position the blade in the extreme right-end of the mechanism.

2F(47) DISPLAYING A TEXT ON THE UPPER LINE OF THE DISPLAY

Data field: Text
Response: None

Text A text of 20 symbols which is sent directly to the display. Prior to this a command for the

positioning and clearing of the upper line. If a fiscal receipt is opened and SW3 is OFF the
command is rejected.

30H(48) OPENING A FISCAL CLIENT’S RECEIPT

Data field: <OpCode>,<OpPwd>,<TillNmb>
Response: Allreceipt,FiscReceipt

OpCode Operator’s number (1 to 16)

OpPwd Operator’s password (4 to 6 digits)

TillNmb Number of the point of sale (a whole number of maximum 5 digits)

Allreceipt The number of all issued receipts (fiscal or not) from the last daily closure up to the moment (4

bytes).

Fiscal Printer SYNERGY PF-550

FiscReceipt The number of all fiscal receipts from the last daily closure up to the moment (4 bytes).

The FP performs the following actions:

- Prints the HEADER

- Prints the tax registration number

- Prints the number and name of the operator as well as the cashier desk number

- Allreceipt and FiscReceipt are returned

The command will not be successful if:

- There is an opened fiscal or non-fiscal receipt

- The maximum number of receipts, as fixed for the day, has already been issued

- The fiscal memory is full

- The fiscal memory is damaged

- No code or operator password available or cashier desk number

- The HEADER contains less than 2 lines

- No tax registration number available

- Wrong operator password

- The clock needs setting

After entering three wrong operator’s passwords the printer blocks and must be switched off and ON again to
restart operating.

31H(49) REGISTRATION OF SALES

Data field: [<L1>][<Lf><L2>] <Tab>[<MKDItem>]<TaxCd><[Sign]Price>[*<Quan>][,Perc]

Response: None
L1 A text of 25 bytes containing one line of description of the sale.
Lf One byte, containing 0Ah.
L2 A text of 25 bytes containing a second line describing the sale.
Tab One byte containing 09h.
MKDItem One byte, containing 40h. This is non-mandatory field which marks current sale as a sale of a

product which is manufactured in Macedonia.

TaxCd One byte containing the letter which indicates the type of the tax. There is a restriction, depending

on the parameter Rates_fewer which is set together with the setting of the type of currency for use
with command 83 (53H).

Sign One byte with a value of ‘+’. Non-mandatory.
Price This is a singular price and it consists 8 meaningful digits.
Quan A non-mandatory parameter setting the quantity of the items for sale. By default this is 1.000.The

length of this parameter is 8 meaningful digits (not more than 3 after the decimal point). The
result Price*Quan is rounded up to the set number of digits and cannot be longer than 8
meaningful digits.

Perc This is also a non-mandatory parameter which sets the value of the discount or surcharge

(depending on the symbol) in percent over the currently performed sale. Possible values are
between - 99.00% and 99.00%, where up to 2 decimal places are acceptable.

The FP performs the following actions:

- The text, describing the sale is printed out together with the price and the code of the discount or

surcharge. If there is a set quantity the information on it is printed out too.

- The price of the items sold is accumulated to the sums already stored in the operational memory. In case

contain a negative sub-total.

‘D’ If the paid sum is less than the sum of the receipt. The residual sum due for payment

is returned to Amount

‘R’ When the paid sum is greater than the sum of the receipt. A message “CHANGE”

will be printed out and the change will be returned to Amount.

‘I’ An error has occurred because the sum under one of the tax groups is negative. The

current subtotal is returned to Amount.

Amount Up to 9 digits with a sign. Depends on PaidCode.

This command starts the calculation of the sums from the fiscal receipt, the printing of the sum with a special font

and showing the result on the display. An additional text may also be printed.

When the command has been successfully executed a further command for opening a cash drawer is activated. If

there is no more data after the symbol <Tab> the printer will automatically pay out the whole available sum in cash.

The command will not be successful if:

- No fiscal receipt has been opened,

- The accumulated sum is negative,

- If some of the accumulated sums under taxation (tax group) is negative.

After the successful completion of the command the fiscal printer will not perform the commands 49 and 51 within the
opened receipt although it can still perform command 53.

Note: The codes of error ‘E’ and ‘I’ will never appear in this version of the printer because commands 49 and 52

(registering a sale) do not accept negative sums.
