Hello Elizabeth,

It's always worth printing a batch of checks and sending them out to see if the bank notices. If they do, then you'll need to get a magnetic toner cartridge for your printer (ours lasted over 5 years!). They're not very expensive, and you only use them when you are actually printing out checks. Of course, the person resposible for printing the checks should have their very own printer attached to their computer within reach so that they can easily confirm that a check run has completed successfully. Sharing a forms printer is a false economy.

Most banks accept non-magnetic toner, but won't admit it if you ask them. If a lot of your checks come back with an attached strip at the bottom, then eventually your bank will complain. Otherwise, you are fine.
