MICR fonts and printing checks

Does anyone have any advice or knowledge about printing checks - specifically the MICR font for the account #/transit#/check # on the check stock itself??

I've got a customer that uses blank check stock - and their old software package printed the MICR font encoding on the check face.

there appear to be lots of fonts available according to a google search i did.

Yeah - we found some fonts - even some free ones (which is always nice!).

Have you ever done this yourself? Is there special placement rules on the check that must be adhered to?

I was hoping to get some info from a person who's done this already so that I can feel confident that it will work for me (and my client obviously!).

Thanks - that site has some really good details!
