Mart POS runs on the web, but many stores still need something very physical: printing receipts and sale documents from a printer connected to the computer.

That is what MPOS Core is for.

What MPOS Core is

MPOS Core is the local app that works as a bridge between Mart POS and the USB printers connected to your device.

In simple terms:

Mart POS runs in the browser
MPOS Core runs on the computer
MPOS Core detects USB printers
Mart POS sends printing requests through that local bridge

This makes local printing possible without forcing the browser to handle everything directly.

What MPOS Core is used for

Its main purpose is enabling local printing from Mart POS.

With MPOS Core, you can:

detect connected USB printers
link Mart POS with the device
choose a default printer
send test prints
print real sale receipts

How it connects with Mart POS

The connection is made through a local link or pairing process.

Once paired:

Mart POS can check bridge status
it can list available printers
it can use the default printer
it can send print jobs to the local machine

The goal is to make printing feel like part of the POS flow.

What happens if MPOS Core is not open

Mart POS can still keep running even if MPOS Core is unavailable.
What changes is local printing.

That means:

you can still use the POS
but printing from that computer will not complete until MPOS Core is open again

Why it is useful in a store

MPOS Core makes printing more practical because it allows stores to:

use USB thermal printers
keep printing inside the sales flow
avoid extra manual steps
validate the printer before operating

For a busy store, that saves time and reduces friction at checkout.

Conclusion

MPOS Core is the key piece that connects the web side of Mart POS with the local printer hardware in the store.

If Mart POS helps you sell in the browser, MPOS Core helps turn that sale into a printed receipt when the business needs it.
