Install the extension: the step-by-step guide, in 7 illustrated steps

Three minutes, no technical skills. The one step people forget is step 4, “Enable on this site”: without it, the extension is installed but is not yet looking after your till. The pictures below show exactly what you will see on screen, using a fictitious POS as an example (your-pos.com).

⏱ Set aside three minutes in one go. The 24 hours of free fix start as soon as you install (step 1): carry on to the first receipt (step 6) right away to make the most of them.

Language note. The extension is currently published under its French name, “SOS Ticket de Caisse”, and its menu is in French. The buttons are exactly where the pictures show them: “Activer sur ce site” = Enable on this site, “Autoriser” = Allow, “Activer ma licence” = Activate my license. An English interface is planned.

Before you start

Step 1 — Install the extension from the Chrome Web Store

Step 1: install the POS Print Fix extension from the Chrome Web Store On the Chrome Web Store listing, click “Add to Chrome”, then confirm with “Add extension” in the browser dialog. Installation is free and takes a few seconds. An “Installed” page then opens, but the extension is not yet active on the till: it still has to be enabled (steps 3 to 5). Step 1 — Install the extension from the Chrome Web Store Free, two clicks, no technical skills. Also works on Edge, Brave and Opera. chromewebstore.google.com POS Print Fix — Restores receipt printing Productivity · Free Add to Chrome 1 Add “POS Print Fix”? It can: • Read and change your data on 127.0.0.1 and localhost Cancel Add extension 2 An “Installed” page then opens: that's normal — but you're not done yet. You still need to enable the extension on your POS page (steps 3 to 5). Until then, nothing changes.
Two clicks: “Add to Chrome”, then “Add extension”.

Open the Chrome Web Store and search for “SOS Ticket de Caisse” (the extension's store name). On the listing, click the blue Add to Chrome button, then confirm with Add extension. It is free and immediate.

An “Installed” page opens: read it, but don't stop there — the extension only acts on your till after step 4. On Edge, Brave or Opera, the same Chrome Web Store listing works; Edge may ask once to “allow extensions from other stores”: accept.

Step 2 — Pin the icon to keep it within reach

Step 2: pin the extension icon to the browser toolbar Click the puzzle piece at the top right of the browser, then the pin next to “POS Print Fix”. The orange extension icon then stays permanently visible in the toolbar, next to the puzzle piece. Optional but recommended: without pinning, the icon remains available behind the puzzle piece. Step 2 — Pin the icon to keep it within reach By default the browser hides it behind the puzzle piece. Two clicks, once. your-pos.com 1 EXTENSIONS POS Print Fix 2 your-pos.com The icon stays visible at all times That's what you'll click in step 3. Optional, but strongly recommended. Without pinning, the icon stays available behind the puzzle piece — just one extra click each time.
Puzzle piece → pin: the orange icon stays visible at all times.

By default, the browser hides new extensions behind the puzzle piece, to the right of the address bar. Click it, then click the pin next to the extension: the orange icon then stays visible at all times. Optional, but you will click it in the next step — and whenever you want to see the receipt counter.

Step 3 — Open your POS, then click the extension icon

Step 3: open your POS software page, then click the extension icon In the same browser, open your online POS software as usual. Once on the POS page, click the orange POS Print Fix icon in the toolbar, at the top right. Nothing changes on the till itself. You must be on the POS page when you click: the extension is enabled for the site shown in the current tab. Step 3 — Open your POS, then click the extension icon Your online POS, like every day. Nothing changes there: it all happens next to it, in the browser. your-pos.com MY POS — Sale in progress 9,90 € 4,50 € 12,00 € TOTAL 26,40 € Print receipt Checkout Where is the icon? Top right, in the browser toolbar — where you pinned it in step 2. Not pinned? First click the puzzle piece, then “POS Print Fix”. Important: make sure you are on your POS page when you click. The extension is enabled for the site shown in the current tab — on another page, it would enable the wrong site.
On your POS sales screen, click the orange icon at the top right.

In the same browser, open your POS software as usual and go to the screen where you print receipts (the sales screen). Then click the orange extension icon, at the top right. Make sure you are on your POS page at that moment: the extension is enabled for the site shown in the current tab.

Step 4 — Click “Enable on this site”

Step 4: in the extension menu, click “Enable on this site” The POS Print Fix menu opens under the icon. The “This POS site” block shows that the site is not enabled yet. Click the orange “Enable on this site” button. This is done only once per POS site: the extension then remembers it, even after a computer restart or an update. If the button does not appear, either the site is already enabled, or you are not on the POS page. Step 4 — Click “Enable on this site” The extension menu opens under the icon. Once per till: after that, it remembers. POS Print Fix Protection active 0 receipts unblocked today Waiting for the first receipt… THIS POS SITE your-pos.com — not enabled yet Enable on this site LICENSE Free fix — 24 hour(s) left What you see 1 The “This POS site” block shows your-pos.com — not enabled yet. 2 Click the orange button “Enable on this site” 3 The browser then asks for your permission: that's step 5. Once per till. The extension remembers it, even after a PC restart or an update. No “Enable on this site” button? The site is already enabled (“enabled ✓” is shown), or you are not on your POS page: go back to step 3.
The extension menu as you will see it: the orange button is the step everyone forgets.

The extension menu opens. In the This POS site block, you see your POS name followed by “not enabled yet”, and an orange Enable on this site button. Click it.

This is the step people forget. Without it, nothing changes: the extension is installed, but it is not yet looking after your till. Once per till: the extension then remembers, even after a PC restart or an update.

Step 5 — The browser asks for your permission: click “Allow”

Step 5: allow the extension on the POS site when the browser asks The browser shows its own dialog: “POS Print Fix is requesting additional permissions”. Click “Allow”. The extension menu then shows “enabled ✓ (ready, nothing to reload)”: printing is restored immediately, without reloading the page, without closing or restarting anything. Step 5 — The browser asks for your permission: click “Allow” The browser itself asks the question, once. No other page is affected. “POS Print Fix” is requesting additional permissions It can: • Read and change your data on your-pos.com Deny Allow THIS POS SITE your-pos.com — enabled ✓ (ready, nothing to reload) Protection active The next receipt will go through the extension. You can print right away. No need to reload the page: the extension is already in place. Close nothing, restart nothing. Go straight to step 6 and print a receipt.
The question comes from the browser itself, once. Then: “enabled ✓ (ready, nothing to reload)”.

Your browser then shows its own dialog: the extension is requesting additional permissions. That is normal: it is asking you to let the extension act on this page, and no other. Click Allow.

The menu immediately shows “enabled ✓ (ready, nothing to reload)”. You have nothing to reload, nothing to close, nothing to restart: printing is restored that very instant.

Step 6 — Print a receipt: it comes out as before

Step 6: print a receipt from the POS, it comes out as before From the POS software, click “Print receipt” as usual. The receipt comes out of the printer. In the extension menu, the counter of unblocked receipts goes to 1 and increases with every print. You have 24 hours of free fix to check on real sales, with no credit card or sign-up. Step 6 — Print a receipt: it comes out as before Your POS's usual button, nothing else. The extension works silently. your-pos.com 9,90 € 4,50 € 12,00 € TOTAL 26,40 € Print receipt the button you already used The receipt prints POS Print Fix Protection active 1 receipt unblocked today Last receipt: 10:42 (your-pos.com) The counter goes up with every receipt 24 hours of free fix to check that everything works.

Your POS's usual button; the menu counter goes to 1.

Do what you do every day: open a sale and click Print receipt. The receipt comes out. Open the extension menu again: the “receipts unblocked today” counter has gone to 1, and goes up with every print.

You have 24 hours of free fix, counted from installation, to check on real sales that everything works as before. No credit card, no sign-up.

Step 7 — After the trial: enter your license key

Step 7: after the free trial, enter your license key in the extension menu When the 24 hours of free fix are over, the extension menu shows “Free fix over — printing paused” and an input field. Paste the key received by email (format SOS-XXXX-XXXX) then click “Activate my license”. The menu then shows “License active”: printing is restored permanently on this till. One key is valid for one till, for life, with no subscription. If the license server is unreachable, printing continues anyway. Step 7 — After the trial: enter your license key Once and for all. The key arrives by email right after purchase. LICENSE Free fix over — printing paused Lifetime license: €59 per till, one-time payment.

Once the 24 hours are over, the menu shows “Free fix over — printing paused” and an input field. Buy your license (€59, once and for all): the key arrives by email. Paste it into the field, click Activate my license: the menu shows “License active”.

That's it, permanently: no subscription, no renewal, no re-entering the key after an update. And if our server were ever unreachable, your printing would continue anyway.

Troubleshooting

The “Enable on this site” button does not appear

Two possible causes: the site is already enabled (the block shows “enabled ✓”), or you are not on your POS page (an empty tab, our website, your email…). Go back to your POS sales screen and open the menu again.

I clicked “Deny” by mistake in step 5

Open the extension menu again and click “Enable on this site” once more: the browser asks the question again.

The receipt still does not print after step 6

Check that your POS software's print utility is running on this PC: it is the one talking to the printer, the extension only restores the link to it. Also check the printer (on, paper, USB cable). If everything is in order and nothing comes out, write to us describing your setup: we will look into it with you.

The browser asks me to “resend the form” / “Confirm form resubmission”

Click Cancel. This dialog appears when a POS page is reloaded right after a sale was validated; “Continue” could record the sale a second time. The extension itself never reloads your page: simply avoid pressing F5 on the sales screen.

I have several tills

Repeat steps 1 to 6 on each PC. One license key is valid for one till; the 3-till pack (€129) contains 3 keys.

I am changing PC

Reinstall the extension on the new PC and enter your key. If it is refused (one key is valid for one till), write to us with your key: we will transfer it to the new PC.
