Method and apparatus for transferring data between a printer and a replaceable printing component

A method for transferring data between an ink-jet printer and a replaceable consumable, the method comprising:

• providing a replaceable consumable having an electrical storage device associated therewith, the electrical storage device configured for transferring a block of data of a selected size to the ink-jet printer, the electrical storage device having a plurality of parameter values logically mapped on the electrical storage device, the plurality of parameter values sized and arranged in blocks of data to ensure no parameter value is transferred in more than one block of data;
• and
• transferring at least one block of the blocks of data between the electrical storage device and the ink-jet printer.

An ink-jet printing system for selectively depositing ink on print media, the ink-jet printing system comprising:

• a printer portion configured to receive a replaceable printing component, the printer portion including a control portion for transferring parameter values between the printer portion and the replaceable printing component, the control portion specifying a block size and address locations for the parameter values;
• and
• the replaceable printing component, the replaceable printing component including an electrical storage device storing blocks of parameter values in address locations, the electrical storage device being responsive to control signals of the control portion for transferring the blocks of parameter values between the printing component and the printer portion, the replaceable printing component parameter values in each of the address locations being sized and disposed within the electrical storage device to ensure no parameter value is transferred in more than one block.
