This is not what we want you to experience, @Theda,

As mention by brconsultingid2 above, you can change the checks font in the printer setup.

You can use coarse and fine adjustments when setting up your printer. This aligns your checks, invoices, and other forms to print on continuous-feed printers. 

For further details in setting up your printer, here's a great resource that you can check: https://quickbooks.intuit.com/learn-support/en-us/print-checks/align-checks-invoices-and-other-forms...

Please feel free to post here in the Community if you have any more questions with QuickBooks.
