@@ -185,33 +185,13 @@ obvious across a room. It only works on a DK-22251 roll — on any other roll th
 it as grey. Two-colour printing is also far slower than black alone (Brother rate it at roughly
 15 labels a minute against 110), which is irrelevant for one badge at a time but worth knowing.
 
-### Printing from the server
+**Driver setup on the kiosk.** Set the QL-820NWB as the default printer for the browser running
+the kiosk, choose the matching paper size in the driver, and set margins to none and scaling to
+100%. Then use **Preview badge** in the console and print one before committing a roll — the
+preview renders at the exact millimetre size the printer will receive.
 
-Set the printer's IP address under **Sites → Edit → Printer** and tick *Print from the server*.
-The server then renders the badge itself and pushes it to the printer over the network, so:
-
-- a kiosk tablet needs no printer driver, no default printer and no print dialog
-- adding a second kiosk means plugging in a tablet, nothing else
-- the badge prints automatically the moment someone completes their sign in
-
-The QL-820NWB has Ethernet and Wi-Fi, so it lives on the network rather than tethered to a
-tablet. Give it a **fixed IP** — a DHCP lease change would silently stop badges printing.
-
-Rendering happens at 300 dpi and 696 dots across, which is the printer's fixed head width on a
-62 mm roll. **Bitmap preview** on the site card shows the exact image that will be sent, and
-**Test print** sends a sample badge. Use both before committing a roll.
-
-**Rotation.** At 0° the badge is laid out across the 62 mm width and runs down the label. At 90°
-it is laid out along the length and turned before printing, which is what you want when the label
-hangs from its short edge. Set it per site and check the bitmap preview — the two look very
-different and only one will suit how you hang them.
-
-**If the printer cannot be reached**, sign in still completes. The kiosk falls back to its own
-browser print dialog, and the failure is shown against the site in **Admin → Sites** with the
-reason. Admins can reprint any badge from the **On site** list.
-
-Leave *Print from the server* off and the kiosk prints through the browser as before: set the
-QL-820NWB as the browser's default printer, margins to none, scaling 100%.
+The QL-820NWB has Ethernet and Wi-Fi, so it does not need to hang off the kiosk tablet. Install
+it as a network printer on whichever device drives the kiosk browser.
