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
Go to Templates
Click Customize
Navigate to Branding and Style
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
