The barcode or item code will not print on my Brother 2550DW?

Welcome aboard to the Community, @Kahanjm.

Let me help you fix the printing issue in QuickBooks Point of Sale.

There are several possible reasons why you're getting unusual results when printing the label. I suggest performing some troubleshooting steps you can try to get back on track.

Please review QuickBook's preferences and ensure you choose the right printer:

1. Choose File > Preferences > Workstation.
2. Select Documents & Printers. Make sure your printer is selected on the appropriate line.
3. Make sure an appropriate Template has been selected for your printer.
4. Select Save.

If the problem persists, I recommend you proceed with checking the Troubleshoot tag printer issues article. It contains detailed instructions you can follow in the order shown (proceed to Solution 3).

For additional information, I've attached an article about the printers supported by QuickBooks Point of Sale: What devices are compatible with QuickBooks Point of Sale?.

Drop me a comment below if you have any other questions. I'll be more than happy to help. Wishing you a good one.

I figured it out. Its a resolution issue. Please make sure people understand that your code doesn't work at higher than 300dpi. This printers default is 1200dpi and its too high for QB POS18. I tried 600dpi and it would print the tag but no image of the barcode was printed, but when dropped the dpi to 300, it printed fine. Once I updated all my clients to default the printer to 300dpi, all worked fine.
