Hi @hojem,
I'll be handing your query about the checks you want to print that you record to pay bills.
On the Pay Bills window, ensure that you selected Check on the Method drop-down menu. Just beside it, make sure the To be printed radio button is selected. You'll then get the Payment Summary window with the option to tap the Print Checks button.
If you need to print several checks at a time, check out this article: Batch print forms in QuickBooks Desktop. The steps listed applies to sales, expenses, and payroll forms.
Do you need further assistance? Post a comment below, and I'll get back to you.
