1. Purpose and Scope

This guide covers printing from multiple POS stations to kitchen, front-counter, and other LAN printers, including orders from online channels. Cloud, Bluetooth, and USB printers require separate validation based on their actual connection capabilities.

Before configuring a printer, decide:

1. Which POS stations connect directly to each physical printer.
2. Which order sources each connected POS station should print.

Do not configure multiple POS stations to automatically print the same order source to the same physical printer. Doing so can cause duplicate tickets, delayed printing, or connection problems.

2. Key Settings

Print Range

Option	Meaning	Typical use
Local Device Only	Handles orders placed on this POS station only.	Use when a secondary POS connects directly to a local printer.
Print across channels	Allows this POS station to print orders from selected sources.	Use when the main POS handles online orders or orders placed on other POS stations.

Sources under Print across channels

Setting	Prints orders from
Other POS orders	Other POS stations in the store.
Kiosk Orders	Self-service kiosks.
QR Code Orders	QR-code ordering.
Online & Mini-Program Orders	Online ordering and mini-programs.
Third-Party Delivery Orders	Third-party delivery platforms.

Print Range controls which orders reach the printer. Kitchen-ticket copy counts, customer-receipt settings, product selection, and notes control what gets printed and how many copies are produced. Check these separately.

3. Option One: Every POS Connects to the LAN Printer

3.1 Connection path

Every POS station that needs to print connects directly to the printer over the local network.

Main POS       ── LAN ── Kitchen Printer
Secondary POS  ── LAN ── Kitchen Printer
Additional POS ── LAN ── Kitchen Printer

3.2 When to use it

• Every POS needs fast printing for its own orders.
• Staff need to print or reprint manually from each POS.
• Low latency matters, and the printer supports the required number of simultaneous connections.

3.3 Configuration rules

Station	Printer connection	Print Range	Source selections
Main POS	Connect to the required LAN printer.	Print across channels	Select only the additional sources needed, such as online, QR, kiosk, or third-party delivery. Do not select Other POS orders.
Other POS stations	Connect directly to the printer they need.	Local Device Only	No cross-channel sources are needed.

The main POS handles selected non-local channels. Leave Other POS orders off so it does not print another POS station's orders again. Each other POS prints only orders created on that station.

3.4 Benefits

• The ordering POS sends print jobs directly to the LAN printer. This shorter path usually reduces delay.
• Every POS with a working printer connection can print or reprint manually from that station.

3.5 Risks and limitations

• POS stations may keep long-lived printer connections. Too many simultaneous connections can make a printer reject connections or report an abnormal status.
• Connection limits depend on the printer model; settings alone cannot guarantee stable multi-POS printing.
• Every added POS requires its own connection, print range, and product-rule checks.

3.6 Before going live

1. Confirm every POS can reach the LAN printer's IP address and print port.
2. On the main POS, select only the required additional channels; leave Other POS orders off.
3. Set this printer to Local Device Only on every other POS.
4. Test from each POS and check for connection errors, duplicate tickets, and delays.

4. Option Two: Print Through the Main POS

4.1 Connection path

Only the main POS connects directly to the printer. Other POS stations do not add that printer. Their orders go through the backend and are delivered to the main POS for printing.

Other POS ──> Backend ──> Main POS ── LAN ──> Printer
Online / QR / Kiosk ──> Backend ──> Main POS ── LAN ──> Printer

4.2 When to use it

• The printer cannot reliably maintain connections to multiple POS stations.
• The store wants one always-on POS to manage printing centrally.
• Other POS stations do not need to print or reprint kitchen tickets manually from their own screens.

4.3 Configuration rules

Station	Printer connection	Print Range	Source selections
Main POS	Connect to every printer managed centrally.	Print across channels	Select Other POS orders and any online, QR, kiosk, or third-party delivery sources the store uses.
Other POS stations	Do not connect to printers managed by the main POS.	Do not configure those printers.	Not applicable.

Keep the main POS powered on, online, and connected to the LAN printer. Otherwise, it cannot print orders received from other POS stations.

4.4 Benefits

• One POS owns the printer configuration, making setup and troubleshooting simpler.
• The printer has only one POS connection, reducing connection conflicts.

4.5 Risks and limitations

• Orders placed on other POS stations must be forwarded through the backend. Printing may be slower than direct local printing.
• POS stations without a connection to the printer cannot manually print or reprint tickets on that printer.
• If the main POS, its app, its network, or its printer connection goes down, all printing routed through it is affected.

4.6 Before going live

1. Confirm the main POS stays on and can print directly to the printer.
2. Choose Print across channels on the main POS. Select Other POS orders and only the other sources actually used.
3. Do not add the centrally managed kitchen or sushi printer on other POS stations.
4. Place test orders from another POS and each enabled channel. Confirm each order prints once at the intended printer.

5. Choosing a Setup

Store requirement	Suggested setup
Every POS must print and reprint locally, and the printer supports multiple connections	Option One: direct LAN connections from every POS.
The printer becomes unstable when multiple POS stations connect	Option Two: print through the main POS.
One fixed kitchen output point and simpler configuration are more important than local reprinting	Option Two: print through the main POS.
Kitchen printing latency must be as low as practical	Evaluate Option One after checking the printer's connection capacity.

When changing setups, remove or disable the old automatic print path for the same order source before saving, syncing, and testing. Do not keep both “each POS prints locally” and “the main POS prints other POS orders” active for the same printer.

6. Product Selection and Multiple Printers

Print range selects the order source. Configure product selection separately for each kitchen printer:

1. Assign each printer a clear role, such as hot kitchen, sushi, drinks, or customer receipts.
2. Under Which products to print, select only the products that station needs to prepare.
3. A product included in multiple rules or printers may print in multiple places. Verify whether that is intended.
4. Save and reload the configuration, then test an order containing products for each preparation area.

7. On-Site Acceptance Checklist

Record the expected printer, number of copies, and actual result for each applicable order source.

Test source	Ordering station or channel	Expected printer	Expected copies	Actual result	Pass?
Main POS order	Main POS
Secondary POS order	Other POS
Online order	Website or mini-program
QR order	QR code
Kiosk order	Kiosk
Delivery order	Third-party platform
Manual reprint	Relevant POS

8. Troubleshooting

One order prints multiple times

• Check whether multiple POS stations connect to the same printer and also accept the same cross-channel orders.
• Check whether a product appears in overlapping kitchen print rules.
• Make sure only one automatic print path is active for each order source.

Orders from another POS do not print

• Option One: confirm the ordering POS connects to the printer and uses Local Device Only.
• Option Two: confirm the main POS selects Other POS orders, stays online, and can print directly.
• Check the printer's LAN connection, IP address, and test print.

Online or delivery orders do not print

• On the responsible POS, select Print across channels and the relevant source, such as Online & Mini-Program Orders or Third-Party Delivery Orders.
• Check that the POS is online, has the latest configuration, and receives a real test order from that channel.

Delayed printing or an old order prints later

• Check whether the responsible POS, app, or network was disconnected and later reconnected.
• Option Two adds backend forwarding and depends on the main POS staying online.
• Check pending print jobs before manually printing again, to avoid extra tickets.

The printer becomes unstable with multiple POS connections

• Consider Option Two and leave only the main POS connected to that printer.
• Remove the printer from other POS stations and retest.
• If Option One is required, confirm the model supports enough concurrent long-lived connections, then add POS stations one at a time and retest.

9. Final Handover

• All POS stations saved and loaded the latest printer configuration.
• Every physical printer has a clear role and connection owner.
• Each order source has one intended automatic print path.
• Relevant products print at the correct preparation station.
• Local orders, other POS orders, online orders, and manual reprinting were tested and recorded.
