I am unable to print from QB Message says "Printing failed. Please check your printer and try again"

I want to make sure you're able to print in QuickBooks Online, @wabvet.

When experiencing unexpected behavior in QuickBooks Online, we recommend clearing the browser cache. If the browser's cache becomes too full of older data, it can potentially cause performance errors. Clearing it will force the system to refresh and get everything back to running smoothly.

You can also use other supported browsers to access your QuickBooks Online account so you’ll be able to print.

I’ve added an article that will help fix common printing problems when using Safari in Mac OS: Troubleshoot printing problems in Safari. 

Please let me know if you need further assistance or if there's anything else I can do for you. I'll be happy to help you some more. 

Thanks for your reply.  I called QB about this issue 10-14 days ago and they told me it was my printer. 

I ordered a new printer, same issue, same message.  Now I am wondering if my OS High Sierra will support the QB online printing?

Thanks for getting back to us, @wabvet.

Yes, your OS High Sierra does support QuickBooks Online printing. To isolate why you still get a prompt message, let's try to print pictures directly from the browser to verify if you get the same message. 

However, if the issue persists, I'd suggest contacting an IT expert. They can check the error and provide you further troubleshooting steps to resolve this,

Also, QuickBooks Online is dependent on your browser's printer settings. You can utilize the troubleshooting steps for the Safari browser in Mac, please see this article for the steps: Troubleshooting printing problems in Safari.
