Hello, pacapparel.

I understand how frustrating it can be that we're not able to print packing slip. Rest assured; we will get this sorted out in just a few simple clicks. 

I've checked and found no reported issues related to this. To check if the browser is already full of frequently accessed page resources causing issues like when you can't print packing slips, let's sign in to your QuickBooks using a private browser.

Here's how: 

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge: Ctrl + Shift + P
• Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N

Once logged in, try to print your packing slip again to double-check. Let's also make sure that our PDF reader and browser is updated. 

If it's successful, let's return your default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.

Aside from that, we can also learn more about handling your sales and other customer transactions through this link: Topics about your company's income and customers.

In case we have other questions about printing packing slip or modifying your invoices, you can always tag me in reply. I'll be here to answer any queries you may have. Stay safe and have a good one!
