this bit about “reporting unknown quantities of data back to hp” let me remember a “cool” feature of the printer. HP takes back the cartridges for free, even sends back the recycling company at their expense, but then the fine print says:

The HP cartridges used with this product contain a memory chip that assists in the operation of the product.

In addition, this memory chip collects a limited set of information about the usage of the product, which might include the following: the date when the cartridge was first installed, the date when the cartridge was last used, the number of pages printed using the cartridge, the page coverage, the printing modes used, any printing errors that might have occurred, and the product model. This information helps HP design future products to meet our customers’ printing needs.

HP collects a sampling of the memory chips from cartridges returned to HP’s free return and recycling program (HP Planet Partners: www.hp.com/recycle) .

The memory chips from this sampling are read and studied in order to improve future HP products. HP partners who assist in recycling this cartridge might have access to this data, as well.

nice data exfiltration program!
