Title: Data compression/expansion method and printer
Inventor: NISHIYAMA TOSHIYUKI
IPC: G06F3/12
Filed: 2000-10-06
Abstract: PROBLEM TO BE SOLVED: To provide a data compression/expansion method that allows a hardware circuit to easily compress/expand data. SOLUTION: First data are acquired, and when the first data are specific data, data denoting a consecutive number of succeeding specific data are acquired, and the addresses of the specific data are summed.
