Lexmark Crushed

Cracking The Lexmark Code

Upon learning Lexmark had used the DMCA to 'protect' its ink cartridges from competition, I decided I had to crack the code in whatever legal and practical way I might manage.

My Z52. The technique works for any Lexmark printer, though.
My first problem was I don't know anything about ink cartridges. My second problem involved not knowing anything about reverse engineering or even liking the printer very much. (I bought it because it claimed to support linux, which it sort of did, but not very well. Then again, it didn't print very well either).
Clearly some ingenuity would be required. And perhaps a new toolset as well.
