Is there a free way to restore receipt printing?

Yes. Chrome and Microsoft Edge offer an enterprise policy called LocalNetworkAccessAllowedForUrls, which exempts specific origins from local network access restrictions. It is free and documented by the vendors. However it requires administrator access to the station, work in group policy or the Windows registry, repetition on every till station, and it does not cover Firefox, which applies its own restrictions since version 153.

Which URL should be allowed in the policy?

The POS site, meaning the origin that makes the request, for example https://mypos.example.com. You do not allow the local destination address such as 127.0.0.1: the policy lists the requesting origins that are exempt from the check.

Why does the setting not always work?

Three reasons come up repeatedly: the policy only applies to managed browsers and has no effect if the station is not properly enrolled, the origin entered does not exactly match the one the POS uses, or a browser update resets the configuration. We have also documented cases where the permission was saved but not applied.

Restore printing for free, without an extension

There is a free method, documented by Google and Microsoft, to restore printing without installing our extension. Here it is in full, holding nothing back. We also tell you honestly when it works and when it will waste your time.

Who this page is for: an IT professional, or a retailer comfortable with group policy and the Windows registry. If those words mean nothing to you, do not attempt it alone: a mistake in the registry can have consequences well beyond your printer. Our extension does the same thing in two clicks, with no administrator rights.

The principle

Since Chrome 142, a web page needs permission to reach a program installed on the station. Browsers provide a release valve for organisations: a policy that exempts specific sites from that check. It is called:

LocalNetworkAccessAllowedForUrls

It has the same name in Google Chrome and in Microsoft Edge, which share the same engine. It lists the origins allowed to make local requests.

Pitfall number one. You enter the address of your POS software — the one shown in the address bar, for example https://mypos.example.com — and not the local address 127.0.0.1. The policy defines who is allowed to ask, not what is reached. This is the most common mistake, and it makes the setting look like it "does not work".

The procedure

Note your POS's exact origin. Open the POS, copy what is in the address bar up to the end of the domain name, without the path: https://mypos.example.com.
On a managed fleet (domain-joined stations): import the Chrome or Edge administrative templates, then set LocalNetworkAccessAllowedForUrls to that origin.
On a standalone station (the typical independent retailer): the same value is created in the Windows registry, under the relevant browser's policies key. This is the step not to improvise.
Close the browser completely (every window), then reopen it.
Check it was applied by opening chrome://policy (or edge://policy): the policy must appear with your value and no error.
Print a test receipt from the POS.

The limitations, stated plainly

✔ It is free and official. Nothing to install, nothing to pay, it is provided by the vendors.
❌ It requires administrator rights on the station. Many retailers do not have them on a machine set up by their provider.
❌ It must be repeated on every till station, and re-checked whenever a PC is replaced.
❌ It does not cover Firefox, which applies its own restrictions since version 153 (21 July 2026) with its own settings.
❌ It is not always applied. We have documented cases where the permission was saved yet had no effect, and browser updates that reset the configuration.
❌ If the origin changes — new domain, a different sub-domain per shop — you have to go back to it.

So, policy or extension?

If you have an IT professional and a managed fleet, do it yourself: it is free and you do not need us. We would rather tell you than sell you something you can get for nothing.

Our extension exists for the other situation, which is the most common one: a retailer with no IT department, a station they do not have admin rights on, several shops to fix the same day, and a till that has to print now. It installs without special rights, is enabled in one click, and survives browser updates.
