How to Print Thermal Billing Invoices from Your Laptop

Choosing the Right Thermal Printer

Thermal printers come in two standard widths:

• 58mm — Compact, ideal for restaurants and small retail
• 80mm — Standard for shops and logistics

Both print at 203 DPI resolution.

Hardware Setup

1. Connect printer — USB or LAN connection
2. Install drivers — Download from manufacturer website
3. Configure paper size — Set to 58mm or 80mm in Windows Settings
4. Test print — Print a sample to verify

Software Configuration

Step 1: Invoice Formatting

Thermal invoices must be formatted for narrow paper. Width typically ranges from 2.25" to 3.15".

Step 2: Font Selection

Use monospace fonts (Courier, Consolas) for thermal printers. They ensure alignment across all printer models.

Step 3: Image Resolution

Thermal printers work best with 203 DPI resolution. Use black and white or grayscale images only.

Step 4: Margin Settings

Set margins to 0.1 inches on left and right. Top and bottom: 0.2 inches.
