I see how important it is to connect the barcode scanner to QuickBooks, It_shws. 

I know you've called in before, however, I still suggest getting in touch with our technical support. An agent has more tools, like screen sharing, which can help you with syncing the scanner. Here's how:

1. Click Help inside QuickBooks.
2. Go to QuickBooks Desktop Help.
3. Select Contact us.
4. Enter "connecting barcode scanner" in the Ask a question field, then click Continue.
5. Select either Message an Agent or Talk to a Specialist. 

Please know we're just around if you have other concerns.
