Hello
Im trying to understand how the hp cartridge works.
i took apart one of the first cartridges -the 26 cartridge and made it print Without the printer which was not so complicated since the adressing is direct.
Now I'm trying to do the same with the new cartridges (the 121 ) whitch is not going so well since the addressing done by a matrix.
i will realy apriciate an edvice .
