I know they have made MICR laser carts for a long time. Was
surprised to see them selling such an item as a MICR ink jet

economically, is to incorporate iron filings. Just having a hard
time believing the can do that without plugging up the jets.

Since the place selling these is a known major spammer, I'm highly
suspect that this is anything other than a private label cart with
regular black ink.

You may well be right, I have no personal experience with them. I
sure don't like spammers, but I'm not sure I'd assume they were
necessarily all frauds.

I was curious enough to call HP; they currently do not sell such a
product and they do not support such a product, and if that product
screwed up your printer, the warranty would be void. Of course, if HP
is hoping to sell such a product themselves one day, they probably
would not be rushing to support it from another company.
