Hello there, @jfpalmtech. Welcome to the Community.
Since printing works fine on your other laptop and mobile phone, the issue appears to be isolated to the device you're having trouble with. The 'printer offline' message when trying to print invoices is typically caused by browser settings, Adobe Reader issues, or local printer configuration on that specific device.
You may want to try opening QuickBooks Online in an incognito or private browser. Alternatively, switch to a supported web browser to verify if the problem persists.
If this doesn't resolve the issue, you may want to consider updating or repairing Adobe using the steps outlined in this article: How to update, repair, or re-install Adobe Reader/Acrobat.
As another troubleshooting step, ensure the printer is set as the default and that its drivers are up-to-date on the affected device.
If the problem persists, here are additional resources that might help:
