Setting Up Plex Mobile for ZPL Label Printing

Overview

Plex Mobile allows shop floor users to (ZPL) labels directly from mobile devices to IP-enabled printers. This guide outlines how to configure default and override printer settings to streamline label workflows.

Requirements

Before beginning setup, ensure the following:

  • A Zebra-compatible printer that supports ZPL and IP printing
  • Plex Mobile installed and accessible on your device
  • Access to the "Physical Printers" screen in Plex
  • Access to the "User Default Physical Printer" screen in Plex

Note: Bluetooth printing is not supported in Plex Mobile. Only IP-based printing is available.

Step 1: Add and Configure a Physical Printer

To make a printer available for Plex Mobile label printing:

  1. Navigate to the Physical Printers screen in Plex.
  2. Click Add on the Action Bar to create a new printer record.
  3. Fill in the following fields:
    • Printer Name: Choose a clear, recognizable name (e.g., “PackingStation_Zebra01”).
    • IP Address: Enter the static IP address of the printer.
    • Port: Use port 9100 for ZPL-compatible printers.
    • Printer Type: Select a type that supports ZPL output.
    • Status: Set to Active.
  4. Click OK to save the printer configuration.

Optional: You may also assign printers to specific workcenters or locations for better routing and visibility.

 

Step 2: Assign a Default Printer to a User

Setting a default printer ensures labels are routed automatically without manual selection.

  1. Open the User Default Physical Printer screen.
  2. Search for the employee by name.
  3. Select the employee from the results grid.
  4. Click Edit on the Action Bar.
  5. In the Default Printer Detail screen, assign the desired printer.
  6. Click OK to save.

Note: Default printers are tied to users, not devices. This allows consistent printing across multiple endpoints.

Step 3: Override the Default Printer (Session-Based)

Use this option when a user needs to print to a different printer temporarily.

  1. On the Mobile Home screen, open the menu.
  2. Select Label Printer Setup.
  3. Choose the Override Printer option.
  4. View available printers.
  5. Select the desired printer.

Note: This override lasts only for the current session and does not change the user’s default printer.

Step 4: Print a Label

Once configured:

  • Navigate to the screen where label printing is available.
  • Tap the Print button at th bottom.
  • The label will be sent to the configured printer.

Reminder: Only ZPL labels are compatible with Plex Mobile.
