Now I use a 3rd party app to print paper checks on blank stock. While this seems to work well, it does mean that I need to take extra steps when printing checks. If they can do this, Quicken should be able to as well.
How, currently, do you print the MICR line on the bottom of that blank stock check? Ordinary black ink/toner isn't sufficient.
I recall an instance, before I retired, where a bank client decided to print their own checks … using ordinary ink rather than the magnetic ink required on the MICR line. When the company refused to remedy the issue, the bank closed the accounts.
According to CoPilot "Blank stock" can mean with and without the MICR line. What's more these days magnetic ink is preferred but not required by most institutions since they are using optical scanners. It also stated that not using magnetic ink is "risky" because the placement and fonts and such have to be very precise.
Sorry, but the IBM 3890 Reader/Sorter, which all of the major banks use to process documents, is NOT optical.
The 3895 was both magnetic and optical … but it never really caught on.
