How to set up a receipt or docket printer?

Connect a network printer to print POS receipts, customer dockets and kitchen dockets from Zeller POS.

Zeller POS connects to printers over your local network, so a few things need to line up first.

Compatible printers:

• Printer Type: Zeller POS connects with Epson and Star receipt printers.

• Connection type: Must be a network (LAN) printer connected via Wi‑Fi or Ethernet. USB-only and Bluetooth-only printers aren’t supported. Zeller POS discovers printers over the same network as the POS tablet.

• Paper: Standard 80mm (3 1/8 inch) thermal receipt roll. Some models also take 58mm.

• Models: Common supported models include the Epson TM series and the Star TSP, mC-Print and mPOP network printers.

Set the printer on the same network:

• The POS tablet and printer must be connected to the same network — Either connected via Wi-Fi or Ethernet. If they’re on different Wi‑Fi networks, the printer won’t appear.
• On a big or shared network (for example a venue with separate staff and guest Wi-Fi, or several access points or VLANs), the tablet and printer also need to be on the same network segment (subnet).
  Zeller POS only discovers printers on the same subnet, so if they're split across subnets or VLANs, the printer won't appear and can't be reached.

Connect a printer:

To get started:

1. Make sure the printer is powered on, has paper, and is on the same network as your tablet.

2. From the main Zeller POS screen, navigate to Settings > Printers.

3. Tap Connect Printer. The app shows Scanning your network and lists the printers it finds.

4. Select your printer from the list, then tap Test Print to confirm it's working.

Can't find your printer automatically? Tap Setup Manually, enter a Printer Name and the printer's MAC Address (for example, TCP:A6:B7:D7:A7:03:87), then tap Connect. (Manual setup still needs the printer on the same network as the tablet.)

Find your printer's MAC address

The MAC address is a 12-character hardware address, usually shown as six pairs separated by colons, for example A6:B7:D7:A7:03:87. Your printer prints it on its own test page. It may print without the colons (A6B7D7A70387), and it may be labelled MAC Address, Ethernet Address or Physical Address. Enter it in Zeller POS in the format shown on the setup screen.

Epson (TM series)

• Make sure the printer is on, has paper, and is plugged into the network.
• Easiest way: turn the printer off and on again while it's connected by Ethernet or Wi-Fi. On start-up it prints a status sheet showing its IP address and MAC address.
• To print one on demand: open the roll paper cover, hold the Feed button for at least 3 seconds, then close the cover. The status sheet prints.
• Some models have a dedicated status sheet button (a small recessed button, sometimes under the bottom cover). Hold it for at least 3 seconds with the paper cover closed.
• Look for MAC Address on the printout. If the IP address prints as 192.168.192.168, the printer did not get an address from your network, so fix the network connection first.

Star (TSP and mC-Print series)

• Turn the printer off.
• Press and hold the FEED button, turn the printer on, and release FEED once printing starts. (On mC-Print models, the power switch is on the front.)
• The self-test prints the firmware versions, interface information, MAC address and IP address. On Ethernet and Wi-Fi models it runs to several pages, so let it finish.
• On the TSP100ECO, leave the power cable connected and the USB cable unplugged, hold FEED, then plug in the USB cable and release FEED when printing starts.

Other things to check on the tablet:

If the printer is powered on and on the same network but still doesn't appear in the list, check these on the iPad itself.

1. Local Network permission (check this first)

Zeller POS can only find printers if iOS allows it to talk to other devices on your network. iOS asks for this permission once, so if it was declined, discovery quietly fails and no error is shown.

• Go to Settings > Privacy & Security > Local Network.
• Find Zeller POS in the list and make sure the toggle is on.
• If the toggle is off, turn it on, then reopen Zeller POS and scan again.
• If Zeller POS isn't listed at all, the permission was never granted on this iPad. iOS has no way to ask again, so delete and reinstall the app to trigger the prompt, then tap Allow when it appears.
• Alternatively, reset the prompts with Settings > General > Transfer or Reset iPad > Reset > Reset Location & Privacy. This avoids reinstalling, but it resets privacy prompts for every app on the iPad, and it doesn't work reliably on all iOS versions.

2. Limit IP Address Tracking and Private Wi-Fi Address

These privacy features give the iPad a rotating or private address on the network, which stops some routers and access points from letting it discover other devices on the local network.

• Go to Settings > Wi-Fi and tap the ⓘ next to the network you're connected to.
• Turn Limit IP Address Tracking off.
• Also check Private Wi-Fi Address. Setting it to Off (or Fixed) is the most reliable on venue networks.
• Forget the network, rejoin it, then scan for printers again.

3. Low Power Mode

• Low Power Mode can throttle background networking and interrupt discovery.
• Go to Settings > Battery and turn Low Power Mode off.
• If the iPad sits on a stand at the counter, keep it on power during service.

4. iOS version

• Go to Settings > General > Software Update and install any available update.
• Running the latest iOS avoids known networking and permission bugs in older versions, and it's one of the first things Zeller Support will ask about.
