Yeah? Try dealing with a printer that has to have a font file sent to it with an lp command from cron every 15 minutes or else checks wont be formatted correctly. AND there is a physical device (either USB on the printer or inline on ethernet in front of the printer) which has the MICR fonts stored.

And then the printer you are migrating the MICR device to has decided it doesn't understand the PCL in the font file anymore.

This is 2017 and I just dealt with this today.
