Check Printer Model / Appearance

This setup guide is for the Star Micronics mC-Print3. It looks like this:


These instructions are how to configure your Star Micronics ethernet receipt printer for use with Molo Workstations.


Important Notes

  1. It's essential you perform Steps 7 and 8 on each and every computer that will use this same printer.
  2. If you are configuring 2 printers, you must perform all steps for the 1st printer on Computer A, for example and then repeat the steps for the 2nd printer on Computer B. We recommend labeling each printer with both its static IP address as well as the name of the computer or station that will be using that printer.


1 - Connect the Printer and Cash Drawer

  1. To start connecting the printer, remove the rear cover by inserting your fingernails or a non-scratching flat tool into the gaps on either side of the back cover. Pull out both sides one-by-one.
  3. Now we'll connect the Ethernet (aka Network) cable. Please make sure the ethernet port you are using is connected to the same network as your computer. Connect the ethernet cable to the LAN Port of a router that is on the same network as the POS Computer. Note: Connecting the Printer to the Computer via Ethernet or Bluetooth will not allow this process to be completed.
  4. Please Note: The printer must be on the same network as the computer that will use the printer.
  6. Now let's connect the power cable. The flat side of the power cable faces inward.
  8. Lastly, if you are using a cash drawer with the printer, please connect the provided cable from the cash drawer to the receipt printer as shown.
  10. Let's now route the cables and close the cover. Cables can be routed through the left (1), center (2), or right (3) pathways for your convenience. Use the visual guides below.
  12. Replace the cover as shown below. Apply the Hooks (A) into the notches in the bottom of the printer. Then pivot the cover upwards so the Clips (B) snap into place. Note: Don't force the cover into place. Make sure no cables are obstruction the cover and that the Hooks (A) and Clips (B) are in the correct location.

2 - Load Paper Into the Printer

  1. Turn on the printer. Note: Having the printer powered on will ensure the paper will feed automatically.
  2. Pull the Opening Lever (1) to open the Paper Cover (2).
  4. Important Note: To prevent a paper jam, carefully wind the paper tightly and make sure the edges are flush.
  5. Ensure the Leading Edge (3) of the paper is on top and feed the paper through the opening.
  7. Press on both sides of the paper cover (4) to close the door. Remove the piece of paper that was automatically cut.


3 - Get the Printer's Initial Dynamic IP Address

When you first connect the printer, it gets a dynamically-assigned IP address. You need to get this address to start programming it.

  1. Turn off the printer.
  2. On the front, press and hold the FEED button and while tapping the Power button turn on the printer.
  3. Once the printer starts printing paper, you may release the FEED button.
  4. The printer will print two separate items. Wait to tear until the second piece comes out.
  5. At the bottom of the second printout you will see the IP Address. Take note of this for the following steps.
    1. If you try to get the printer's IP address and the receipt paper prints with 0.0.0.0. it means the printer isn't connected to the network or the network port isn't connected. Please review that the Ethernet cable from your Router to the Printer is connected.


4 - Assign the Printer a Static IP Address

  1. Open the web browser of the computer that will access the printer.
  2. Navigate to the IP address you received in step 2 above.
  3. Click System Access --> Login.
  4. The default username is root and the password is public.
  5. NOTE: You will be required to pick a new password but you can simply enter public again and press Save. If you choose to change the password, please take note of this password and save it.
  6. Click IP Parameters.
  7. Choose Static.
  8. Set an IP Address that you're sure is available for static use and won't be assigned by your DHCP server/service.
  9. Set the Subnet Mask and Default gateway to match your current network settings.
  10. Click Submit.
  11. On the screen that says Static address condition is accepted! make sure to click Save in the Network Configuration menu. If you don't press Save, the changes won't be saved to the device.
  12. When prompted, select Save --> Configuration printing --> Restart device.


5 - Generate a Self-Signed Certificate

  1. Open a new browser window or tab.
  2. Navigate to the Static IP Address you setup in step 3 above.
  3. Click System Access --> Login.
  4. The default username is root and the password is public.
  5. Click SSL/TLS in the Network Configuration menu.
  6. Click Create Self-Signed Certificate.
  7. Use the following settings:
    1. Country Name: US
    2. State or Province Name: use the 2-letter abbreviation of your state. Example: FL
    3. Locally Name: enter the name of the city where the marina is located. Example: Miami
    4. Organization Name: enter the name of the marina. Example: Waterfront Marina
      1. Note: Don't put special characters in the organization name. Just letters, spaces, and numbers.
    5. Organization Unit: Marina
    6. Domain: enter the static IP address from step 2. Example: 172.16.0.245.
    7. Expiration Date: 2030 / 12 / 31
  8. Click Create.
  9. When presented with Create Self-Signed Certificate OK, make sure to click Save.
  10. Return to the SSL/TLS menu item.
  11. Click Create Self-Signed Certificate.
    1. NOTE: You do not have to fill out the information again even though it appears as blank.
  12. Now click Download.
  13. Make sure to save this certificate. If you replace the computer, you will need to install this certificate on the replacement computer.


6 - Install the Self-Signed Certificate on the Computer

These steps are for Windows. Click here for the steps for a Mac. Click here for the steps for an Ipad.

  1. Rename the certificate so when you store it for future use you know to which printer it belongs.
  3. Double click the certificate file and if prompted accept to open the file with the Crypto application.
  4. Click Install Certificate in the pop-up window.
  5. Choose the Local Machine option.
  6. Click Next and accept the Windows Security warning.
  7. Choose Place all certificates in the following store.
  8. Click Browse.
  9. Choose Trusted Root Certification Authorities.
  10. If setup correctly, your window should look like this before pressing Next.
  12. Click Next and then Finish.

7 - Setup the Printer in Molo

Important Note: Since the receipt printer triggers the cash drawer to open, it is Molo's recommendation to use 1 receipt printer for each point-of-sale workstation. You can however allow multiple workstations to print to the same printer but this can cause multiple workstations to open the linked cash drawer.

  1. Log into Molo.
  2. Go to Admin Settings --> Admin --> Receipt Printers.
  3. Click to create a new receipt printer.
  4. Give the printer a name and enter the IP Address from the steps above.
  5. Note: We recommend labeling the printer with the name and IP address.
  6. Save the entry and then click Make My Default Printer.
