The P255 model incoporates the unique mosaic printer of the other P-models,
It permits the average speed of 4 lines/s.
The calulator can perform the four basic arithmetic functions and furthermore,
is provided with three accumulative stores of 14 digits capacity,
a percentage key, a square root key, a constant key and a 'change sign'-key.
The engraved key symbols correspond to the symbols printed on the tally strip,
so that every calculation can easily be traced afterwards.
The calculator is almost identical to the PHILIPS: P255,
 which has two accumulative stores instead of three.
