Checker prints the payee and amount like the financial programs. The difference is that unlike the others it also prints information that you are now paying big money to have pre-printed on your checks. It prints all those account numbers, routing codes and the strange looking numbers on the bottom of your checks . Checker will work with any inkjet or laser printer. You can use inexpensive check paper available at any print shop.
Some users simply use the paper they use every day.
But I recommend that you use blank check stock. It is available from the Checker Software company for about .05 per check, and you can also find it locally at just about any print shop. As a software consultant I hate software that is complicated or confusing. That's why I love Checker. It is simple, straightforward, user friendly and a very quick learn.
