Absolutely.it's a bad idea in the sense that HP has already done the math and KNOWS it will make more money this way vs simply price gouging on the ink costs itself
the network connected printers have been feeding them plenty of data for many years now and they have already made sure any such plan is advantageous to only one side of the transaction. i believe the saying goes "the house ALWAYS wins"
so for them it's a pretty good idea, but for everyone else it is most likely not going to be a very good thing.
Then, you have to fold in the convenience factor for the customer.
Money is most of the equation, but not necessarily all of it.
