BRUH Print

What it is

A Home Assistant add-on that drives a USB DYMO LabelWriter directly — no CUPS, no spooler, no PPD, no filter chain. About 300 lines speaking the printer’s own raster protocol over a bulk USB endpoint, which is the same shape the CUPS DYMO path has printed with for twenty years, minus four more places for a job to get stuck.

A real designer

Text, barcodes, QR, images and shapes, dragged into place with snapping, alignment and nudge — in the sidebar, not a separate app.

One word, biggest possible

Type Rice, get Rice at the largest size that fits — chosen by trying every way of breaking the words across lines, not just one.

Templates

A saved label with blanks. Fill them in on the panel, or from an automation.

It knows what is loaded

A LabelWriter cannot tell you what stock is in it. BRUH Print remembers — and refuses the one print that ruins a roll.

What you need

• A DYMO LabelWriter on USB. The 450 family is the reference; an unrecognised model is driven, not refused — it gets the 450’s geometry and its twin-roll flag is read from the device’s own product string.
• Home Assistant on a machine you can plug it into.
• The add-on’s USB permission, which is a manifest permission the Supervisor grants when it creates the container — not a switch on the Configuration tab. It takes effect on the next restart.

The one thing it refuses

Sending a 2.25″-wide raster to a 0.56″ roll prints across the liner — once per copy, with no error anywhere. A run of fifty ruins fifty labels.

So a stock/roll mismatch is the single reason a print is refused. Everything else that could be wrong — a barcode that will not fit, an image that could not be read, a fixed font size that clips — comes back as a note beside a label that still prints.

A refusal is always somebody unable to work.

Printing from Home Assistant

Service	What it does
bruh_print.print_text	One line (or a few words), autofitted
bruh_print.print_template	A saved template with its blanks filled in
bruh_print.print_label	A full label document
bruh_print.reprint	The last thing, again
bruh_print.set_roll	Record what you just loaded
bruh_print.print_test	A ruler label, for measuring

Plus a Lovelace card for the dashboard, which reads the sensors and calls the services — never the panel. It runs in whoever’s browser is looking, which may be a phone on mobile data through Nabu Casa; it has no route to the ingress port and no business having one.
