Browser configuration for Scan & Label
In order to use Scan & Label to scan and print product labels, you will need to do a one-time browser configuration the first time you use the tool. Instructions for Chrome and Firefox are provided below. Internet Explorer and Firefox for Mac are not currently supported.
You also have the option of downloading your labels in PDF format by clicking the Download Label button within the Scan & Label tool.
Setting up Scan & Label with Chrome
Within the Scan & Label tool, click Printer Settings and set width to a minimum of 100 mm and height to a minimum of 25 mm.
Note: You can improve the quality of the label by increasing size. For best results, ensure that the height of the label is greater than half of the width.
Open the Chrome print preview screen by clicking the Print Label button.
Under Destination, ensure that your thermal printer has been chosen.
Click on + More settings to expand the settings panel.
Set Paper size to the appropriate size based on your labels and printer.
Change Margins to None.
Note: If you have alignment issues, you can manually adjust the margins by selecting Custom. The margins can be set to any value between 0 and 1. You may need to experiment to find the best settings for your printer. If you have a blank page after your label, set Pages to 1 to print only the first page.
Enter the number of copies you would like to print and click the Print button.
Setting up Scan & Label with Firefox
Note: Firefox for Mac is not currently supported.
If you have manually changed your printer settings in the about:config page, please reset them to default before continuing with the steps below. To reset a setting in the about:config page, search for the setting, right-click and select Reset.
If any of the setting names mentioned below do not appear in your search results, create the setting by right-clicking the middle of the page, selecting New, and then choosing the appropriate data type based on the criteria below:
If the setting value is true/false, select Boolean.
If the setting value is a number, select Integer.
If the setting value is text, select String.
Enter the setting name and click OK. Enter the desired value and click OK to create the setting.
Steps for Firefox on Windows
Open a browser window and enter "about:config" into the address bar.
Click the I'll be careful, I promise! button.
Enter "print_printer" in the search box at the top of the page. Double-click on the text print_printer in the search results, and type the name of your thermal printer in the box that appears. Click OK.
Close Firefox and open a new Firefox browser window.
Enter "about:config" into the address bar and click the I'll be careful, I promise! button.
Enter "print.show_print_progress" into the search box at the top of the page. Under the Value column, you should see "false" for this entry. If it is not set to false, double-click on print.show_print_progress to set it to false.
Enter "print.printer_[NAME_OF_YOUR_THERMAL_PRINTER].print_margin_top" into the search box at the top of the page. Double-click the entry, enter "0", and click OK.
Note: Do not include the brackets around the name of your printer. If your printer name has spaces in it, replace the spaces with underscores (e.g. "Test printer" should be entered "Test_printer").

Enter "print.printer_[NAME_OF_YOUR_THERMAL_PRINTER].print_margin_left" into the search box at the top of the page. Double-click the entry, enter "1", and click OK.
Repeat step 9 for "print.printer_[NAME_OF_YOUR_THERMAL_PRINTER].print_margin_right".

You can also adjust the page orientation by updating the "print.printer_[NAME_OF_YOUR_THERMAL_PRINTER].print_orientation" setting (set to 0 for portrait or 1 for landscape).
Enter "print.printer_[NAME_OF_YOUR_THERMAL_PRINTER].print_footerleft" into the search box at the top of the page. Double-click the entry, remove any text present in the text box, and click OK.

Enter the number of copies you would like to print and click the OK button.
Note: If necessary, you can improve the quality of the label by increasing its size. Within the Scan & Label tool, click Printer Settings and increase the label height and/or width. For best results, ensure that the height of the label is greater than half of the width.
Silent printing
Silent printing allows you to print labels without needing to go through the print confirmation window.

--kiosk-printing --enable-print-preview
Click OK.
Use this shortcut when you want to use silent printing.
Disabling silent printing for Chrome
Right-click the shortcut that has silent printing enabled and select Properties.
Under the Shortcut tab, remove the following from the end of the text in the target field:
--kiosk-printing --enable-print-preview
Click OK.
