Abstract
Methods and apparatuses for changing firmware in a gaming printer. The printer containing computer memory, internal and/or external to the printer, with the memory divided logically into multiple parts; a first section containing computer codes, a second section containing the data describing the format of gaming vouchers, and a third section containing data describing the format of promotional coupons. A mathematically unique identifier is created as an individual signature for each section of the memory, with each signature being independent of the other signatures, thus allowing for the changing the contents of one or more sections of the memory without affecting the contents of the unchanged sections of the memory.
