Printing tags can be accessed in two places:
1) under manage products if you want to print a single tag for an item
2) You can print tags from a purchase order from the Action Menu.
Set Up Your Printer
- Printer settings page size should correspond with the tags loaded in the printer and the label size selected for printing in MicroBiz.
- Adjust margins and make sure you are not printing headers and footers in your browser print dialogue.
Other Ways of Doing This
If you need a custom format all labels can be exported to comma and tab separated export files which can typically be imported by professional label printing software.
