Abstract

PURPOSE:To distribute all dots into a reticulate form, by calculating and recording the interpolating data to plural dots which are recorded in adjacent to each other in an input data. CONSTITUTION:An input data A is supplied to a data input terminal 12 for printing. In this case, a 1-line data is equal to a time-division data which has a time slot accoring to dots (k) equivalent at least to a line. Such input data B is supplied to a time axis compressing circuit 22 to be compressed down to 1/2. This compressed data C is fed to an adder circuit 23, a 1-dot delaying circuit 24, a 1-line delaying circuit 25 and a 1/2-line delaying circuit 26 respectively to obtain data D, E and F. The circuit 23 adds the data C, D, E and F together and then compresses the added data down to 1/4 to calculate an interpolating data in the form of a mean value of each data.
