Abstract
A printing device with a data memory efficiently stores character code data and other attribute data in a limited memory region. If a character code of a print data input from the keyboard is a space code, the print data is nullified, and a pitch data corresponding to the space code is added to the pitch data corresponding to the character code previously stored in a correction memory. Namely, the data are compressed. Since only the print data excepting the space code data is stored in the memory, the limited memory region is efficiently used.
