Troubleshooting Static IP Assignment Failures
Assigning a static IP address to Bixolon receipt and label printers ensures that POS terminals and office workstations maintain a permanent communication handle across power cycles.
When a printer fails to ping, displays network timeouts, or disappears from network discovery immediately after assigning a static IP, configuration mismatches are responsible.
Step 1: Check Subnet Mask and Default Gateway Mismatches
A typographical error in the subnet mask or gateway renders the printer unreachable from other subnets:
- Print network self-test: Power on the printer while holding the Feed button to print the current network parameters.
- Verify IP address range: Ensure the static IP matches your local router subnet (e.g., if router is
192.168.1.1, printer must be192.168.1.xxx). - Confirm Subnet Mask: Ensure the Subnet Mask matches your network exactly (typically
255.255.255.0). - Verify Gateway IP: The Default Gateway must match the internal IP address of your network router.
Step 2: Detect IP Address Conflicts with Other Devices
Assigning an IP address already in use by another computer or tablet creates an IP collision:
- Turn off the Bixolon printer: Switch off the printer's power switch completely.
- Ping the assigned IP from PC: Open Command Prompt on Windows, type
ping 192.168.1.xxx(inserting the assigned printer IP), and press Enter. - Check for active replies: If you receive replies while the printer is turned off, another device is using that IP.
- Choose unassigned IP: Assign a different, unreserved IP address outside the router's active DHCP assignment range.
Step 3: Reset Network Interface via Net Configuration Tool
If the printer interface is locked and unreachable, reset the network card to DHCP defaults:
- Direct Ethernet connection: Connect an Ethernet patch cable directly between the printer and your PC's Ethernet port.
- Set PC to temporary static IP: Configure your PC Ethernet adapter to
192.168.192.100with subnet255.255.255.0. - Launch Bixolon Net Config Tool: Open the Bixolon Net Configuration Tool and click Search Devices.
- Reset or reassign: Re-enter the proper network parameters or toggle back to DHCP and click Save to Printer.
Frequently Asked Questions
What is the default factory IP address of a Bixolon network printer?
The default factory static IP address for unconfigured Bixolon Ethernet cards is typically 192.168.192.168.
How do I test if my POS terminal can reach the printer's port 9100?
From a command prompt or terminal, run telnet [printer-ip] 9100 or use PowerShell's Test-NetConnection -Port 9100.
Does the printer require a physical reboot after saving a static IP?
Yes, power off the printer for 10 seconds and power back on to re-initialize the network interface controller with the new parameters.
