  • Replaceable cartridge for a printer including resident memory with stored message triggering data
    Patent number: 6113208
    Abstract: A method for controlling an inkjet apparatus employs a pluggable module which includes a memory, the inkjet apparatus being connected to a computer/display arrangement. The method includes the steps of: determining when the pluggable module has been installed in the inkjet apparatus; determining if a printer driver indication in the module memory notes a newer driver procedure than the current driver procedure being used with the inkjet apparatus; and if yes, displaying a message indicating availability of the newer driver procedure. The method further enables the occurrence of a low ink indication from a pluggable ink module to automatically cause the display of a reorder message. The method also enables any selected message included in the memory to be automatically displayed upon insertion of the pluggable module.
