I had a Lexmark Z52, i think, for about 3 days. It wanted to phone home to PaPa every time I used it or Booted. Lexmark denied it tried to access the internet, but ZA caught it everytime & blocked it. There was no way to disable it from trying to get on the internet. LexMark used one driver for standalone & networked printers.
It just looked for a NIC & decide that I must want to let the world have access to my system. It proceeded then to get on the internet with its message that I was available.
I gave it to someone that used it on a non-internet system.
Good printer,copier, scanner at $139 for those people that are not parnoid on privacy.
