I have two printers. Can I set up a default printer in QBO just for check printing?
I can provide some clarification on this printing question, @arkvalleyinfo.
Whenever you select to Print a list, report, or check in QuickBooks Online, the information is prepared in a printer-friendly form and then handed over to your internet browser to be printed. This means that any settings relating to default printers have to be selected within the browser you're using. Popular QBO browsers like Google Chrome generally support only one default printer, so I'd recommend reaching out to their support team to see if they offer any options for selecting different default devices based on printing source or operation.
There are also a plethora of QuickBooks Online compatible third-party apps that may be able to help you achieve this functionality. To browse them, head to the Intuit App Center at the link and enter a keyword like printing in the search bar. Doing this will empower you to customize how your QBO works to make your everyday tasks easier and more efficient.
