I can help you configure your printer setting so you can print your checks in reverse order. I'll show you how:
In the Printing preference, choose Layout. On the Page order field, you can select Back to the front to print it in reverse order.
Click OK to the printer settings window.
It may also depend on your printer. Thus, some printers print pages by default in reverse order. You may want to consider checking your printer's manual to know how to change the setting.
You can also visit our Intuit Marketplace to see which checks are compatible with QuickBooks Online.
