Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The answer to your question depends upon what sort of computer you have. Please tell me whether it is a Windows PC, or an Apple computer. Thanks.
(You probably need to set the driver settings on the computer to that form length, is certainly the first thing to recommend. Whether your computer, that you print the checks from, matters only in that instructions on how to access the driver settings on the computer, differ from Apple to Windows computers.)
