Calculator for polygraphy
The calculator for printing is used for quick and convenient calculation of the cost of printing on certain parameters.
It is convenient both for the manager and for the buyer. On the manager side, the calculator is convenient because it clearly sees
the exact consumption of paper and it does not need to be calculated by itself, because this is the work of the program.
For the buyer, he is convenient because he does not have to count anything, you just need to choose the paper size and enter the circulation,
so he will receive the final cost that he will pay.
