Abstract

Printer (1) receives revised operating code in flash memory (19). To preserve offset adjustment unique to the printer, the values in new operating code are compared with those in the previous code, and new offsets preserving the previous offsets are stored in permanent memory (21). The use of permanent memory is minimized by basing the calculation on changes from start of production.
