Can only print one check at a time. They will not print correctly?.

Hello there, johnfteel.

If you want to print multiple checks, you'll only have to tick the Print later box within the check. 

Then, print the checks from the print queue. Here's how:

1. Go to the +New button.
2. Select Print checks.
3. Load your checks into the printer. In the Starting check no. field, enter the check number of the first check in the printer.
4. Select the checkbox next to each check you want to print.
5. Select Preview and print.
6. Click Print.
7. If your checks print correctly, select Done.

For more information, I'd recommend checking this article: Learn how to print a check from your print queue. I can see you've shared above that your checks are not printing correctly. In this case, let's proceed using other compatible browsers when printing them. The odd behavior may occur of the incompatibility of the check and the browser you recently use.

If the same thing happens, let's use this article and review on how to fix common printing issues in QuickBooks Online: Fix QuickBooks Online printing issues on browsers.
