Abstract
The present invention involves the use of onboard sensors which determine the printer's ambient environment for the purpose of selecting the printer's optimal operational subroutines. Conditions such as temperature and humidity are measured at the time of printer operation, the measurements being communicated to a processor wherein the printer's operational subroutines are set. The processor employs memory which is accessed via a table look-up arrangement using the measured temperature and humidity. The memory is divided into plural sectors, each of which stores a set of operational subroutines for use by the printer when it is situated in an environment characterized by predetermined temperature and humidity ranges.
