Thanks for reaching out to the Community, @ctmorgan78.
To check if this is a browser-related (cache and cookies) issue, try signing into your QuickBooks Online (QBO) using a private browser (incognito). There are times that the browser is already full of frequently accessed page resources, causing some unusual responses.
Here's how:
- Press Ctrl + Shift + N (Google Chrome).
- Ctrl + Shift + P (Firefox).
- Control + Option + P (Safari).
Once logged in, try to print your packing list/slip again to double-check. Refer to this article for further guidance: Create and print a packing slip.
If the customer PO number is showing, return to your default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.
For tips and other resources, I recommend visiting our website for reference: Self-help articles.
