STAR mC-P: Setup & Troubleshoot

Initial Setup (5-7 min):


  1. Download the MC2 or MC3 Printer Mac/Windows Drivers by clicking here (if you are unsure which options to select click here for help). 
  2. Once downloaded see the images below on how to open the file and install the Star Micronics App






Mac OS X


Make sure you are using a recommended device. There are various MCP Printers (WiFi, Ethernet/LAN, Bluetooth, and USB). You can generally see the model on the bottom of the printer. A WiFi model would appear as TSP143IIIW whereas an Ethernet/LAN model TSP143IIILAN. Depending on the model there are different setup steps that are outlined in the TSP100 Window or Mac setup guide seen below.


USB Model Setup: 

  1. Once the zip file in step 1 is downloaded please follow the steps here from the Star website to finalize the installation. Please go through each menu item on the right-hand side of the screen to complete the setup. 
  2.  Continue to "Mandatory Printer Settings (2-5 min):" below. 

LAN & WiFi Model Additional Setup: 

    1. Open the Mac OS X Setup Guide (Wifi & LAN Pg. 10 | Bluetooth Pg. 13) OR Window Setup Guide (USB Pg. 7 | WiFi Pg. 16 | LAN Pg. 24 | Bluetooth Pg. 32)
    2. After step 1 is complete and you have added your printer to your computer. You will need to set the IP Address on the Printer AND Router to a Static IP Address. Below are steps on how to set the printer to a static IP.
      • As for setting your router to a static IP this depends entirely on your router model and varies case by case. In general, you will need to locate your router, find the label on your router that says router login, then follow the steps to log in to your router. You may also contact your internet service provider to help set a static IP on your router.
      • The IP address might change when the printer or router/printer is reset, setting the IP to STATIC will make sure the printer always functions properly. 
    3. See the setup guide above and navigate to WiFi or LAN setup section, review setting static IP, or follow my steps below.
    4. To do this please enter the Printers' IP address in the browser URL. Example
      • To obtain the printer IP address you will need to power off your printer, press & hold the feed button, then power on your printer while continuing to hold the feed button. The printer will print & cut three different items. Do not let go of the feed until the third document is printed (about 5-10 seconds). Example here of the parameter you are looking for. 
    5. Star Network Utility will launch 
    6. On the left-hand side of the screen click Login
      • Username: root (all lowercase)
      • Password: public (all lowercase) 
        • NOTE it will require you to change the password before you can edit your IP settings. PLEASE DO NOT LOSE THIS PASSWORD. Write it down and tape it on the back of the printer, save it, etc. If you lose this password you will have to factory reboot the printer and start over. 
      • Click IP Parameters
      • Click Static 
      • Enter the IP Details from step 3 (see example here
      • You can leave the other items blank, click save. Then click save on the left-hand side of the network utility tool. Save and reboot the device
      •  Continue to "Mandatory Printer Settings (2-5 min):" below.
