Printing

Flow Retail has extensive support for printing on various types of printers, split into three different categories:

• Receipt printers

• Label printers

• A4 printers

Connecting the printers

There are basically two ways of connecting a printer to Flow Retail:

a) via a Flowbox

b) directly over the network

Connecting via a Flowbox

Please check out Flowbox documentation for details.

Directly over the network

Make sure you printer is available directly over public IP, and has either an active LPD (port 515) printer queue or Jetdirect (port 9100-9102) printer queue.

Printing over the network directly to the printer requires direct IP access to the printer's IP address and port. In most cases this is NOT possible unless you use Flow Retail Enterprise, with a local installation of the platform.

Receipt printers

Thermal Printers

Thermal printers are typically situated in the checkout area for printing receipts. They utilize heat to create images on paper, allowing for easy installation and minimal upkeep. The paper comes in easily replaceable rolls.

Requirements

Label printers

Used to print various types of labels, like price labels or delivery notes to stick onto products for later pickup.
