4 FP-550F
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.
In support of the lower level of the protocol there is a DOS driver for installing in
CONFIG.SYS. This driver is “responsible “ for the correct transfer of the commands
and the receiving of the results from their execution. Using this driver restricts the
process of operating the printer down to the saving and the simple reading of a file -
also possible under Windows.
Another possible shortening of the control operations of the FP- 550F is the 16-bit
library-type file FPLIB.DLL, which contains all existing commands for the printer and
where the initial processing of the data, returned by the printer.
Together with the printer DATECS offers a Windows-based program called
FPSERV.EXE, which generates all fiscal reports demanded by the local fiscal legislation.
Some basic adjustments and settings to the printer can be performed under this program
too, like: setting the clock, entering new “headers and footers”, editing the number and
size of the tax rates when legislative changes appear.
