PRINTING METHOD IN PAGE PRINTER

摘要

A page printer for forming an electrostatic latent image on a printing drum by expanding print data consisting of character data, etc., into image data consisting of a dot matrix in an expansion unit, storing the matrix for each band in a raster buffer RAM, and outputting this image data for each band. Data corresponding to the expanding time for each band in the expansion unit are in advance prepared and stored for each band in a band management memory, the longest time necessary for the expansion is calculated from the data stored in this band management memory, a rotating speed of the printing drum is calculated on the basis of this longest time and the rotating time of the printing drum is thus optimized. In this way, prints with white gaps can be prevented.
