No, i dont.
If i did, and the software that came with the printer did "phone home" with the fact that I rpinted 14 pages, using only black ink, and 5 pages in colour, so what...
How has my privacy been invaded by this data being gathered?
What harm have I been done, or potentially could be done to me, by Lexmark knowing this?
It's no different from the tills in Tesco's, that record the fact (for example) that the average shopper purchases 6 eggs, one loaf of bread, 8 pints of milk, a a tin of baked beans....
It's data, yes, and data about you, but not data that actually identifies you.
Even if the data was connectable to you, how will I be harmed by lexmork knowing that I print 5 letters a week, and 2 photo's?
