If power has failed during the printing of a daily report, after switch ON, the device
will print the message “DUPLICATION SAVE” in an expanded bold type and will
restart the execution of the command (i.e, printing will be resumed).
ISSUING FISCAL AND NON-FISCAL RECEIPTS
A) Non-fiscal receipts
The receipt is first opened, a text is then printed and the receipt is closed. The com-
mands 38(26H) are used, an indefinite number of times the command 42 (2AH) and
39(27H).
B) 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
108(6CH) - daily financial report with or without clear, print out of the
sums from the different items included
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 key SW4.
