Using GST Pro with a Label Printer

Updated Apr 13, 20261 min read

You can use GST Pro templates with a label printer. However, due to the smaller print size, the default font may appear too small on printed labels.

This can be easily fixed using Custom CSS.


Why This Adjustment is Needed

Label printers typically print on smaller paper sizes (e.g., thermal labels), which can make:

  • Text appear too small

  • Important details harder to read

By increasing the font size, you can make your invoices more readable when printed.


How to Adjust Font Size

  1. Go to Templates

  2. Click Customize

  3. Navigate to Branding and Style

  4. Scroll down to see the Custom CSS section


Add Custom CSS

Copy and paste the following code into the Custom CSS field:

.template-invoice,.template-invoice *,.template-invoice table.styled-table td,.template-invoice table.sublime td {  font-size: 13px !important;}

What This Does

  • Increases font size across the entire invoice

  • Ensures better readability on small label prints

  • Applies consistently to tables and text elements


Optional Adjustments

You can tweak the font size based on your printer:

  • For slightly larger text:

    font-size: 14px !important;
  • For compact labels:

    font-size: 12px !important;

Tips for Best Results

  • Test print a sample invoice before finalizing

  • Adjust font size depending on your label dimensions

  • Ensure important fields (amount, GST, totals) remain clearly visible
