After finalizing a configuration, click File → Export XML. Save this to a cloud drive (OneDrive, Google Drive). If your configuration PC dies, you can restore with one click.
Seamless, driver‑free printing over TCP/IP – now smarter and more stable than ever.
Even after setting a static IP on the printer, go to your router’s DHCP Reservation table and reserve that same IP for the printer’s MAC address. This creates a double layer of stability.

Guide to Using the GP Ethernet Printer Tool (Printer Test V5.0)
The GP Ethernet Printer Tool, often titled Printer Test V5.0 in its software interface, is a critical utility for configuring Gprinter (Gainscha) and other compatible thermal receipt and label printers. Its primary purpose is to manage network settings, specifically for printers equipped with an Ethernet (LAN) interface. Key Functions of Printer Test V5.0 gp ethernet printer tool v5.0
IP Address Configuration: Manually change a printer's IP address to match your local network's subnet.
Network Discovery: Search for and identify all printers connected to the local area network (LAN), even if they are on a different IP segment.
Device Testing: Perform self-tests and print test pages to verify connectivity and hardware status.
Ethernet Port Settings: Refresh and view the local PC's IP to ensure the printer and computer can communicate correctly. Step-by-Step Setup Guide 1. Identify the Printer’s Current IP
Before using the tool, you must know the printer's current IP address. Most Gprinters default to 192.168.1.100.
Self-Test Method: Turn the printer off. Press and hold the FEED button while turning the power back on. Release the button after a few seconds. The printer will produce a printout containing its current IP address, Gateway, and Subnet Mask. 2. Connect the Hardware After finalizing a configuration, click File → Export
Plug your thermal printer into your network router or switch using an Ethernet (RJ45) cable.
Ensure your computer is connected to the same network (either via Wi-Fi or another Ethernet cable). 3. Using the Tool to Change IP Settings
Launch the Tool: Open the Printer Test V5.0 application on your Windows PC.
Search for Printer: Click the Search Printers button. The tool will scan the LAN and list any detected devices.
Select Device: Highlight the printer you wish to configure from the results list.
Enter New IP: In the "New IP Address" field, enter an IP that is compatible with your router (e.g., if your router is 192.168.0.1, set the printer to 192.168.0.200). Seamless, driver‑free printing over TCP/IP – now smarter
Apply Settings: Click the button to update the printer's internal memory. The printer may beep or restart to confirm the change. Troubleshooting Common Issues
Printer Not Found: Ensure the computer's firewall is not blocking the tool and that the physical Ethernet connection is secure (look for a blinking link light on the RJ45 port).
IP Mismatch: If you cannot "ping" the printer after changing the IP, verify that you haven't assigned an address already in use by another device on your network.
Driver Installation: After setting the IP, you must still add the printer in Windows via Settings > Bluetooth & Devices > Printers & Scanners by creating a "Standard TCP/IP Port" using the new IP address.
If the printer does not appear: Check your Ethernet cables. If the IP of the printer is completely outside your computer's subnet (e.g., your PC is 192.168.1.x and the printer is hardcoded to 10.0.0.1), older tools failed. V5.0 is smarter—try using the "Net Config" or "Add Device" feature manually if auto-search fails.
When support calls are inevitable, the tool generates a comprehensive .txt export including ARP table entries, switch port responses, and last 50 internal printer errors.
GP Ethernet Printer Tool v5.0 is a lightweight Windows utility that sends raw print data directly to Ethernet‑connected printers using TCP/IP ports (typically 9100). Instead of relying on manufacturer drivers or Windows printer queues, it writes directly to the printer’s native command language (ESC/POS, ZPL, EPL, etc.). The result? Faster, more predictable printing – especially in retail, hospitality, and logistics environments.
