Printer Offline

If you're unable to print, follow these steps to troubleshoot. After each step, check to see if you can print; if you still can't, then move on to the next step.

Before you start, take the time to identify your printer model so you know which instructions apply to you.

Step 1: Make sure the printer isn't paused.

Printers will not print if they're paused. Depending on the model of your printer, you'll see different indicators if the printer is paused.

T800: "OFFLINE" in top-right corner

The OFFLINE text means the printer is paused. Unpause it using the green pause button [      I I      ] below the screen.

ZD621R: Pause indicator above screen

If the PAUSE light is lit up yellow, the printer is paused. Unpause it using the Pause button [ I I ] to the right of the screen.

ZD500R: PRINTER PAUSED message flashing on screen

If the printer's screen flashes PRINTER PAUSED, unpause it using the Pause button [ I I ] to the right of the screen.

Step 2: Refresh the Print Client.

Using the Support Tool, select the Refresh Print Client option.

If you haven't installed the Support Tool, follow these instructions: https://kb.simplerfid.com/books/support-tool/page/installation

Do not select the "Repair Print Client" option unless instructed by our support team. Doing so will require us to manually re-assign your station, leaving you unable to print until then.

If you find that you have to Refresh the Print Client often, it may help to adjust the sleep settings on your host PC.

Step 3: Check the software

Please make sure that no antivirus software (e.g. Microsoft Defender or Sophos) blocks Simple RFID Print Client and Simple RFID Print Client Updater.

Step 3:4: Check the printer's USB connection.

Occasionally, the Host PC will put certain USB ports to sleep in order to save power.

Unplug the USB cable from both ends then plug it back in.

Step 4:5: Power cycle the printer.

Printers can encounter software errors which cause them to stop responding to the host.

Turn the printer off for 30 seconds, then turn it back on.

  • T800: Turn the printer off using the power switch on the back.
  • ZD621R: Turn the printer off by holding down the Power button to the left of the screen.
  • ZD500R: Turn the printer off using the power switch on the back.

Step 5:6: Completely reinstall the Print Client.

If the Print Client still remains offline and all the steps above are exhausted, you can completely uninstall the Print Client and install it from scratch.

If this step is applied, your host PC will get unassigned and should be assigned again by our team. It will take some time

  1. Make sure that you have Print Client installed:
        1) Go to Windows Control Panel > Programs and Features
        2) Find Simple RFID Print Client Updater (if absent, please install)
  2. Reinstall Print Client:
        1)  Go to Windows Control Panel > Programs and Features
        2)  Uninstall Simple RFID Print Client Updater
        3) Go to C:/ProgramData
        4) Remove the "Simple RFID" folder
        5) Download and install the print client (see Installing Print Client)
  3. Notify Simple RFID

Email: support@simpleRFID.com

1. Please make "Connect Printer" the subject
2. In the body of your email include:
• The name of your company
• The Device name of the host PC/Mac
• Name of the location where your printer is connected
( This refers to the physical location where the printer is located (e.g. which warehouse or store the printer is in).
If you are setting up your printer before your first training, you can disregard this step as you will not have any locations set up yet. )
