The trial version will print TRIAL watermarks on checks. Once you purchase ezCheckPrinting and enter the key code, you will remove it. All your data will stay.

Please feel free to contact us if you still have any questions. We are glad to assist you.

Thanks,

We are looking at your EZ Check Printing (MAC Version). We have preprinted checks and we would like to use your software to fill in the checks and print them from a laser printer. Is there a way we can set up the template so as to fill specific locations on the actual preprinted check?
