Hi there, Whoadeb.

When you print a check voucher with items, there's only a limited list of products and services appears. Once items are many, these will not show all in the check voucher. However, I suggest printing the check that has many items through the report. Then, customize this to show all the checks created with specific data.

Here's how:

1. Click the Banking menu at the top.
2. Choose Banking and select Check Detail.
3. Click the Customize button.
4. Go to the Filters tab and choose Transaction type in the search bar.
5. Choose Check from the drop-down arrow. Then. Click OK.
6. Choose the specific date in the Dates drop-down list.
7. Click the Print icon and choose either Save as PDF or Report.
8. Follow the onscreen instruction to finish the process.

So how can I get them to not print on the voucher below the check if they won't all fit?

Thank you for getting back to this thread, @Whoadeb.

You can follow the steps given by my colleague ChristieAnn, to print the check that has many items through the report. 

 Or you can also print the checks one at a time. You can follow the steps below:

1. In QuickBooks Desktop, select Banking, then choose Write Checks. Find or create the check to print.
2. Enter a check number in the First Check Number field if necessary, then select Print.
3. Select the check style (Voucher, Standard, or Wallet), and make sure that the correct printer name is displayed. Then select Print.
