# Printronix: Update Firmware via Webpage

<p class="callout warning"><span style="white-space: pre-wrap;">To use this upgrade method, your printer </span>****must be connected to your network****<span style="white-space: pre-wrap;">. If a network connection is unavailable, </span>[****update the firmware via a USB flash drive****](https://kb.simplerfid.com/books/printers/page/printronix-updating-firmware-via-flash-drive).</p>

#### Requirements:

- A device with a web browser, on the same network (LAN) as your printer
    - This device must be able to download and upload files.
- An RJ-45 Ethernet cable to connect your printer to the network (unless you have a Wi-Fi enabled printer)

### Step 1: Download the latest firmware file

Choose the appropriate file for your printer model:

- [T800 firmware (T820, T830)](https://dl.simplerfid.dev/T800%201.52E%20P302271.prg)
- [T4000 firmware (T4204)](https://dl.simplerfid.dev/T4000%20V1.46H.prg)
- [T6000e firmware (T6304, T6604)](https://dl.simplerfid.dev/T6000e%20V1.42E.prg)

### Step 2: Connect the printer to your network

<p class="callout warning"><span style="white-space: pre-wrap;">Make sure </span>****all****<span style="white-space: pre-wrap;"> </span>****USB cables**** are disconnected from the printer before continuing.</p>

Using an Ethernet cable with RJ-45 connectors, or Wi-Fi on supported models, connect the printer to your network.

When the printer is connected to the network, you will see its IP address at the top-left of the screen:

[![Printronix IP address.png](https://kb.simplerfid.com/uploads/images/gallery/2025-07/scaled-1680-/printronix-ip-address.png)](https://kb.simplerfid.com/uploads/images/gallery/2025-07/printronix-ip-address.png)

<span style="white-space: pre-wrap;">(If you don't see this screen, you may need to unpause the printer using the green pause button \[ </span>****I I****<span style="white-space: pre-wrap;"> \].</span>

### Step 3: Navigate to the printer's web page

Type the printer’s IP address into a web browser. You can omit leading zeros in each octet:

![image.png](https://kb.simplerfid.com/uploads/images/gallery/2025-07/scaled-1680-/1B9image.png)

You should be greeted with the printer's home page:

<p class="callout info"><span style="white-space: pre-wrap;">If you see a page asking you to set a password, we recommend setting it to </span>****Print123!****<span style="white-space: pre-wrap;"> to remain consistent with other guides.</span>  
If you set the password to something else, make sure you store the password somewhere it can be retrieved later.</p>

### Step 4: Capture the printer's current configuration

When you upgrade the firmware, the printer's current settings (including calibration, print intensity, vertical/horizontal shift, and more) will be lost. We will save the printer's current configuration to a file so we can restore it after the upgrade is complete.

<span style="white-space: pre-wrap;">Click the </span>****Printer****<span style="white-space: pre-wrap;"> link at the top of the Configuration list.</span>

<p class="callout info"><span style="white-space: pre-wrap;">You may be prompted for a username and password at this point. The username is </span>****root****<span style="white-space: pre-wrap;"> and the password is </span>****Print123!****<span style="white-space: pre-wrap;"> or whatever you set it to in the previous step.</span>  
<span style="white-space: pre-wrap;">If </span>****Print123!****<span style="white-space: pre-wrap;"> doesn't work, try leaving the password field blank.</span></p>

<span style="white-space: pre-wrap;">Click the </span>****Upload****<span style="white-space: pre-wrap;"> button. This will download a file containing the printer's current configuration. Save this file; we'll use it later to restore the configuration.</span>

<p class="callout info"><span style="white-space: pre-wrap;">You may be prompted for a username and password at this point. The username is </span>****root****<span style="white-space: pre-wrap;"> and the password is </span>****Print123!****<span style="white-space: pre-wrap;"> or whatever you set it to in the previous step.</span>  
<span style="white-space: pre-wrap;">If </span>****Print123!****<span style="white-space: pre-wrap;"> doesn't work, try leaving the password field blank.</span></p>

<span style="white-space: pre-wrap;">After a few minutes, the printer will reboot itself and apply the update. During this time, the web page will be unresponsive. After </span>****~2-3 minutes****, the upgrade will be complete.
