Payment Setup

Use Payment Setup

Use Payment Setup to connect in-store and online processors and configure checkout stations, card terminals, receipt printers, and cash drawers.

Before you start

  • Have access to the payment-provider account you are connecting.
  • Know which payment processor should be used for POS card payments.
  • Power on physical terminals/readers and connect them to the internet.
  • Install the printer manufacturer’s normal driver before asking MintLGS to discover that printer.
  • Decide whether each station needs browser printing only or the optional MintLGS Hardware Connector for silent printing and drawer control.

What success looks like

  • The active POS processor controls which terminal provider appears in POS.
  • Registered terminals can be selected from POS for the active processor.
  • Paired checkout computers report their printer and cash-drawer status to the assigned station.

Quick start

The shortest path through this area.

  1. 1Open Sales > Payment Setup.
  2. 2Use Overview to see whether In-store payments, Online payments, and POS setup need attention.
  3. 3Connect the in-store processor used by POS and choose the default when more than one is configured.
  4. 4Connect the online processor used for storefront and event checkout and choose its default.
  5. 5Open POS setup to create checkout stations, register or pair payment terminals, and configure printers or cash drawers.
  6. 6Open POS at the location and station and complete an approved test for each payment or hardware path.

Common tasks

Open only the task you need.

Connect an in-store or online processorIn-store connections serve POS; online connections serve storefront and event checkout.
  1. 1Open In-store payments or Online payments based on where customers will pay.
  2. 2Choose the processor and complete its connection or setup flow.
  3. 3Return to Payment Setup and confirm it is connected and active.
  4. 4If more than one processor is connected in that area, choose the default.
  5. 5Run a small real or approved test transaction before relying on it during store hours.
Set up a checkout station and card terminalA station identifies the counter and warehouse; card terminals remain selectable in POS.
  1. 1Open POS setup, then Checkout stations, and create a clearly named station for the counter.
  2. 2Open Payment terminals and register or refresh the processor’s available devices.
  3. 3Pair a Square Terminal in MintLGS, register a Stripe reader in Stripe and refresh, or review connected Clover devices as appropriate.
  4. 4Open POS at that location and station, then choose or confirm the expected terminal before card payment.
Install and pair the Hardware ConnectorUse the Connector when a station needs silent printing, automatic printer selection, a drawer connected through a printer, or dependable background drawer control.
  1. 1Use the Connector only on a 64-bit Windows 11 checkout computer. Macs, tablets, ChromeOS devices, and computers where you cannot install software should use browser hardware instead.
  2. 2Install the printer manufacturer’s normal driver first and confirm the printer appears in the computer’s printer settings.
  3. 3Open POS setup > Printers & drawers and choose the checkout station before doing anything with its hardware.
  4. 4Download and install the MintLGS Hardware Connector on the computer physically connected to the printer or drawer. It installs for your Windows user and does not need administrator access.
  5. 5Choose Create setup key in MintLGS, copy the one-time key, and paste it into the setup page that the Connector opens in your browser. The key expires after ten minutes and works once.
  6. 6Return to MintLGS and confirm the selected station shows the Connector as installed, connected, and running. The Connector then stays in the Windows notification area instead of leaving a terminal or app window open.
Register and assign a receipt printerThe selected checkout station owns its printer assignment; similarly named printers on another computer are separate devices.
  1. 1Open POS setup > Printers & drawers, choose the station, and confirm its Connector is running.
  2. 2Under Available on this station computer, find the real printer queue and choose Register. Do not register a PDF, document, fax, or other virtual printer.
  3. 3Choose Configure. Keep Operating-system printer driver for the safest compatibility, or choose Raw thermal only when the printer language and model are known.
  4. 4Set receipt width and, for tested raw thermal printers, the language, character set, paper feed, and cutter behavior. Save the printer setup.
  5. 5Choose Print sample receipt and confirm the physical width, text, feed, and cutter. The sample is an example receipt, not a customer transaction.
  6. 6Choose Use for receipts or select the printer in the station’s Receipt printer assignment.
Set up a drawer connected through the receipt printerThe drawer is a relationship to the station’s thermal printer, not a second physical device to discover or repeatedly add.
  1. 1Connect the drawer cable to the receipt printer’s dedicated drawer port, not to a computer network or telephone port.
  2. 2Configure the registered receipt printer and choose Raw thermal printer only after confirming its command language.
  3. 3Enable A cash drawer is connected to this printer and save. MintLGS creates the linked drawer once and shows Cash drawer configured.
  4. 4Confirm the assigned drawer says Connected through followed by the receipt printer name. Assign it as the station’s Cash drawer if it was not assigned automatically.
  5. 5Choose Test drawer. Change the connector pin or pulse timing only when the printer or drawer documentation requires it.
Set up a direct USB drawer with the ConnectorA serial port is only a possible adapter; register it only when you recognize the physical drawer adapter.
  1. 1Connect the supported USB drawer trigger or serial adapter to the station computer and refresh the hardware list.
  2. 2Find the recognized adapter under Available on this station computer, register it, and choose Configure.
  3. 3Select the adapter command and connection settings from the adapter documentation, save, and choose Test drawer.
  4. 4Assign the tested device as the station’s Cash drawer.
  5. 5If supported, fully close the drawer and choose Calibrate sensor. Sensor unavailable does not prevent opening; it means MintLGS cannot reliably report open versus closed.
Use browser hardware without installing the ConnectorBrowser mode is useful for tablets, ChromeOS, occasional printing, or computers where staff can approve prompts.
  1. 1Open Point of Sale on the device, sign in, and choose the location and checkout station.
  2. 2Open More (…) in the POS header and choose Hardware.
  3. 3Choose Browser print dialog for receipts. The device’s normal print or share dialog opens for every receipt.
  4. 4Desktop Chrome or Edge can also choose a compatible direct USB or serial drawer and approve the browser device prompt.
  5. 5Test the drawer before use. Browser mode cannot silently select a printer and cannot open a drawer connected through a receipt printer.
Reconnect a payment service safelyReconnect when the service reports expired permissions or the dashboard asks for authorization again.
  1. 1Finish or cancel any payment currently in progress.
  2. 2Open the affected processor in Payment Setup and choose Reconnect or Disconnect followed by Connect, as shown.
  3. 3Complete the authorization and verify the active status and default selection.
  4. 4Check the available terminal list and perform a test before reopening that payment method to staff.

How this area works

Reference information for the choices on this page.

Square Terminal setup
  • If the terminal is already logged into Square directly, log out first.
  • Choose the log in with code flow on the Square Terminal.
  • Generate the pairing code in MintLGS and enter it on the terminal.
  • The terminal may look idle or blank until a payment is sent from POS.
Stripe reader setup
  • Register the reader inside Stripe using the code shown on the reader.
  • MintLGS discovers readers registered to the connected Stripe account.
  • Refresh the terminal list after registering a new reader.
  • Stripe test cards are for test-mode setups, not production live card processing.
Checkout stations and terminal selection
  • A checkout station names the physical counter and belongs to a warehouse.
  • Payment terminals are selected in POS and only devices for the active in-store processor are shown.
  • Mark the station used most often at a location as the default, but create separate stations for separate checkout computers.
Printers and cash drawers
  • Choose the checkout station first. Everything below it applies only to that station and the computer paired to it.
  • Browser mode needs no MintLGS installation. Staff open POS > More (…) > Hardware to use the print dialog or approve a compatible direct drawer on that browser.
  • The optional Hardware Connector discovers installed printers and supported direct drawer adapters on the station computer. The current self-service download supports 64-bit Windows 11; browser mode remains available on macOS, ChromeOS, tablets, and other devices.
  • The Connector runs in the Windows notification area without a terminal window. Its tray menu shows connection and update status and provides Payment Setup, diagnostics, disconnect, startup, update, legal, and quit actions.
  • Pairing is limited to the MintLGS environment printed on the setup screen. The one-time key expires after ten minutes, and the saved connection is protected by the signed-in Windows user’s credential encryption.
  • Register and physically test a device before assigning it. Virtual document, PDF, fax, and similar print queues cannot become POS receipt printers.
  • The operating-system printer driver is the safest default. Raw thermal mode should be used only after the printer language, width, character set, cutter, and drawer-port behavior are confirmed.
  • A printer-connected drawer is created once by enabling A cash drawer is connected to this printer. It then displays as connected through that printer.
  • Receipts are created by MintLGS and use the same browser or assigned printer path for Stripe, Square, Clover, cash, store credit, and split-tender sales.
Receipt and cash activity locations
  • Print an example receipt from the registered printer card to test layout, width, text, feed, and cutter without using a customer sale.
  • Print the completed sale receipt from the POS success screen, reprint it from POS History, or print it from Dashboard Orders.
  • Staff manage drawer shifts, cash movements, counts, and manual opens from POS > More (…) > Cash drawer.
  • Managers review all drawer shifts and activity from Payment Setup > Overview > Cash drawer activity.
  • Manual drawer opens record the staff member, station, reason, connection route, and command result. Only the Other reason requires a note.
Actions on the Payment Setup page
  • Use Overview for connection status and direct links into In-store payments, Online payments, and POS setup.
  • Use In-store payments to connect and choose the default provider used for POS card payments.
  • Use Online payments to connect and choose the default provider for storefront and event checkout.
  • Use POS setup > Checkout stations to create, enable, disable, default, or delete a named counter for a warehouse.
  • Use POS setup > Payment terminals to refresh devices, pair Square terminals, and review Stripe or Clover devices.
  • Use POS setup > Printers & drawers to pair a checkout computer, register devices, test them, and assign station hardware.
  • Use Pair Square Terminal only when Square is the active POS processor and the terminal is in the log in with code flow.
  • For Stripe, register readers in Stripe first, then use Refresh in MintLGS to locate online readers from the connected Stripe account.
  • Only terminals for the active in-store processor should appear in POS terminal selection.

Troubleshooting

Choose the symptom that matches what you see.

A terminal is missing from POS

Confirm the active POS processor, terminal registration, account connection, and terminal online status.

The card terminal screen is blank

An idle screen can be normal before a payment is sent. Send a payment from POS to confirm the terminal enters the payment flow.

A printer or cash drawer is missing

Choose the intended checkout station first. Confirm the Hardware Connector is installed, connected, and running on the computer physically attached to the device. Make sure the printer has a usable operating-system printer queue, then refresh. Register only a direct drawer adapter you recognize; a drawer connected through a printer appears after enabling that relationship in the printer setup.

The Connector is offline or needs to be reconnected

Open the Windows notification area and select the MintLGS Hardware Connector. Its status explains whether setup, an update, or an internet connection is needed. If it was reinstalled or lost its setup, choose Create reconnect key for that checkout station and paste the new one-time key into the browser setup page. Do not pair the same computer to a different counter unless its station assignment is intentionally changing.

You need to remove the Connector from a checkout computer

Open the Connector tray menu and choose Disconnect this computer before uninstalling when possible. Then remove MintLGS Hardware Connector from Windows Settings > Apps > Installed apps. Disconnect revokes that computer’s MintLGS connection; uninstall removes its local pairing, logs, and startup entry. Printer and drawer assignments remain in Payment Setup so a manager can review or reuse them after pairing a replacement computer.

The printer is visible but cannot be registered

The computer may see the USB device without having a usable printer queue. Install the manufacturer driver, confirm the printer appears in the operating system’s printer list, print an operating-system test page, then refresh MintLGS.

The sample receipt prints incorrectly

Return to Configure and check receipt width. Keep the operating-system driver unless you have confirmed the printer’s raw language. If raw mode is required, verify language, character set, feed, and cutter one change at a time, printing a new sample after each save.

The drawer opens but its status is unavailable

That is expected for many drawers connected through a printer and for simple USB trigger adapters. Sensor unavailable means the connection cannot reliably report open versus closed; it does not mean the drawer-open command failed.

Terminal name is rejected

Use a short, readable name with regular letters, numbers, spaces, hyphens, or apostrophes.
