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 performes 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 Bulgaria these letters are À,Á,Â,Ã.
Each of the taxation groups has a set tax rate (in percent) which is expressed by a digit
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.
