Just amazing QB is being asked on many occasions about being able to use barcodes in sales orders, purchase orders, or just templates in general.  The only workaround I have found is to add a barcode font (128 etc you can find online or pay for) into QB and use that font for the field you want to "barcode" in the template.  So for instance in your template you can setup a field for the sales order number and have that fields font be "Barcode 128" and it will show a barcode when you print the sales order.  The only caveat in my case is my barcode reader has to have * before the start of what I want read with the scanner and * at the end.  EX *123456* .  I have my customer numbers in *23456* format and my sales orders are sequentially in *1234* to *1235* to *1236*.  I now need to just have barcodes show up without using the * due to a connector I'm adding to QB.  So I am at a loss now.  Wish QB would listen to their customer base and include printing barcodes on templates that represent the typical data found on the templates such as sales order numbers, purchase order numbers etc.  I know this is probably close to engineering the next Space X mission for Elon though...
