Hardware go-live checklist

Run through this once, on-site, before you open the doors. It’s the final check that the hardware you set up in this section actually works together — the printer prints, the drawer pops, and (for a network printer) only your registers can reach it. Each item links to the page that explains it.

Which parts you need depends on what you ring sales on:

• Tablet POS — the tablet prints straight to a network printer. Do Printer & cash drawer, Tablet tills, Network & security and the Final test. There’s no print agent to install and no USB pairing — skip those sections.
• Web register with a network printer — do everything except Tablet tills. Read Receipt printers & devices first: it covers what the print agent does and doesn’t print.
• Web register with a USB printer plugged into the computer — skip ahead to USB printer?.

Printer & cash drawer

• You’ve chosen an 80mm thermal (ESC/POS) printer — and a network one prints over port 9100. See Choosing a receipt printer.
• The cash drawer is plugged into the printer (RJ-12), or you’re using a USB-trigger drawer.
• The printer is wired in with Ethernet (not Wi-Fi) and powered on.

Tablet tills

• Your printers are added on the tablet’s Station screen, each with its network address. See Stations.
• Each till is bound to the printer at its counter — or, for a second device with no drawer of its own, set to ring for the station that has one. See Set up this till.
• On each till, Test receipt prints a sample and Test cash drawer pops the drawer.

Print agent (web register with a network printer)

• The print agent is installed as a Windows Service on a store PC on the same network. See Installing the print agent.
• The PC is set never to sleep while plugged in (powercfg /change standby-timeout-ac 0).
• In Settings → Devices, the agent shows online and that it can reach the printer.

Network & security

• The register tablets, the printer, and (if you use one) the print agent PC are all on the same local network. See Setting up your store network.
• The POS gear is on its own segment, and the printer’s port 9100 is reachable only from your register tablets and the print agent PC (if you use one). See Securing your store network.
• Each printer’s default admin password is changed and unused services are turned off.
• From a device that is not one of those, you’ve confirmed you can’t reach the printer on port 9100.

Final test

• On each tablet till, you’ve rung up a real cash sale: the receipt printed cleanly and the drawer popped.
• On the web register, you’ve rung up a real sale and printed its receipt the way Receipt printers & devices describes for your setup.

That’s go-live. If a tablet’s receipts ever stop printing, start with Test receipt on its Station screen and its print log. On the web register with a print agent, start at the agent’s online status in Settings → Devices.

USB printer?

A USB printer plugged into the register is much simpler — there’s no print agent or store network to set up:

• The printer is plugged into the register computer and powered on.
• You’ve paired it in Receipt printers & devices.
• Test print prints and Test drawer-kick pops the drawer.
• A real sale’s receipt prints with Print (thermal).
