Why: The printer is receiving raw text in a language it doesn’t understand (e.g., PCL instead of TSPL/ZPL). This often happens with USB direct printing.

Solution:

Q: Is there a 64-bit driver for the GP-1324D on Windows 11?
A: Yes. The standard driver from Gprinter is 64-bit. Most Windows 10 drivers are also 64-bit and work flawlessly.

Q: Can I use the GP-1324D with Bluetooth on Windows 11?
A: The standard GP-1324D model is USB-only. If you have the “GP-1324D-BT” variant, pair it via Settings → Bluetooth & devices, but you still need the driver installed. The Bluetooth connection will create a virtual USB COM port.

Q: Why doesn’t my GP-1324D print from Microsoft Word or Chrome?
A: Word and Chrome use standard page sizes (Letter, A4). You must create a custom 4x6 paper size as shown in Part 4. Additionally, in Chrome, use “System Print Dialog” instead of Google’s built-in preview.

Q: Does the GP-1324D work with Windows 11 Home edition?
A: Yes, perfectly. There are no restrictions. Some group policy tweaks are not available, but the basic driver installation works.


If the official driver fails, Seagull Scientific provides Windows 11 WHQL-certified drivers for GP-1324D (paid license required for full features). Free trial available for testing.

Before installing:

Method A – Using the installer (recommended):

Method B – Manual installation via Windows settings:

The GP-1324D prints on continuous rolls, fanfold labels, or die-cut labels. You must set the correct paper size.

For shipping labels (UPS, FedEx, Shopify):
Set the same custom size inside your shipping software (e.g., ShipStation, Pirate Ship) and match it to the driver.

Sometimes, Windows 11 will automatically fetch a compatible driver if you enable “Optional Updates.” To check:

In my experience, this is rare for this specific model. Stick with the official website.
