Before you start

Will it work with what you already own?

Everything below is written down as either checked on the real thing or not checked yet, and the difference is never blurred. Where something cannot work, the reason is given rather than the row left out.

What the labels mean

Only one of these means somebody ran it and looked at the result. The rest say honestly how far short of that we are.

Checked
Somebody ran this on the real thing and looked at what came out. Nothing weaker earns this word β€” a passing test is not it, and neither is a manufacturer saying so.
Partly
It works, but not all of it. The row says which part is missing and why.
Experimental
It works and you can use it, but it is new and may still change shape. There is always a plainer way to do the same thing.
Not checked
RobCo Depot is built to work with it and nobody here has confirmed it. That is a gap in what we know, not a warning about the thing itself β€” it may well be fine.
Will not work
It cannot work as things stand, for the reason the row gives. Some of these are waiting on us; others are decided by the browser or the hardware and are not ours to change.

What the columns mean

The grids below use short headings so a column stays narrow enough to compare down. Here is the long version of each, once.

Label printers

Any printer your computer can already print to will print labels through the ordinary print dialog. A supported model can also skip that dialog, which is faster when you are printing a batch β€” but it is a convenience on top of a path that always works. Checking these is the hard part, and we would rather say so: we do not have one of every printer on a desk here, so a model can be fully supported in code and still sit at β€œnot checked” until somebody has run a real label through it and looked at the result. Where we could not test, the row says so instead of implying more than we know. We are doing our best with the machines we can get our hands on β€” and if you own one of these, hearing how it went is genuinely useful, whether it worked or not.

Label printers
What it is Status Direct print Print dialog Print station
Any printer you can already print to
Details

An office laser, an inkjet, anything. RobCo Depot sizes the page to the label and hands it to your usual print dialog. This is the path that always works, and it is never taken away from you β€” a direct print that fails falls back to it and says so.

Checked Prints without the print dialog: No Prints through the print dialog: Yes Sends a label to a print station: No
DYMO LabelWriter 450
Details

The printer this was built against and the one labels have actually come out of. With DYMO Connect installed it prints without a dialog, in a batch, straight from the page.

Checked Prints without the print dialog: Yes Prints through the print dialog: Yes Sends a label to a print station: Yes
DYMO LabelWriter 450 Turbo, Twin Turbo, DUO, 4XL and 5XL
Details

The same family, the same local printing service, and every reason to expect them to behave the same. Nobody here has had one on a desk to confirm it, so it stays unchecked until somebody does.

Not checked Prints without the print dialog: Yes Prints through the print dialog: Yes Sends a label to a print station: Yes
DYMO LabelWriter 550 and 550 Turbo
Details

The printing side works like the 450. The catch is the roll: this model reads a chip in the label spool and refuses stock that is not DYMO's own, so the cheaper third-party rolls people buy for a 450 will not feed. That is the printer's firmware, not a setting.

Partly Prints without the print dialog: Yes Prints through the print dialog: Yes Sends a label to a print station: Yes
Zebra
Details

Not yet. Zebra is the obvious second brand β€” it has its own local printing service that works much the way DYMO's does β€” but RobCo Depot has no support for it written yet, so today a Zebra prints only through the ordinary print dialog like any other printer.

Brother QL-700, QL-810W
Details

Yes, over USB, and nobody here has printed one yet. Brother publishes how to talk to these printers, so the app builds the label itself and sends it straight down the cable β€” no extra software to install. Two things to know. On Windows the Brother driver holds the cable and the browser is refused it, so the label goes to the ordinary print dialog instead unless you change how the printer is installed; on Android and Linux it simply works. And the QL-810W can print red, which this app does not use: a label here is black on white.

Not checked Prints without the print dialog: Yes Prints through the print dialog: Yes Sends a label to a print station: Yes
Phomemo M110
Details

Yes, over Bluetooth, and nobody here has printed one yet. It is a pocket printer, so a phone or a laptop can send a label to it directly with nothing installed. Two limits. You have to pick the printer from a list each time you print β€” Bluetooth works that way in a browser, and it means a print station cannot use one: a label sent from a phone needs somebody present to choose the printer. And it takes rolls up to 48 mm wide; anything wider is refused rather than printed with its edge missing. The M200 is not offered, because how wide its head is has not been established.

Not checked Prints without the print dialog: Yes Prints through the print dialog: Yes Sends a label to a print station: No
Niimbot B1
Details

Yes, over Bluetooth, and nobody here has printed one yet. Like the Phomemo it is a pocket printer a phone can reach with nothing installed, and like the Phomemo you have to choose it from a list each time β€” so a print station cannot use one. Only the B1 is offered. Niimbot printers differ from one another more than most ranges do, in ways that are not fully written down anywhere, and getting one of those details wrong does not print a slightly wrong label β€” it prints noise. If you own another model and want it added, that is a short job with the printer in front of somebody.

Brother P-touch label makers
Details

No, and not for want of trying. The P-touch handhelds and the Cube talk over an older kind of Bluetooth that no browser can open at all β€” this is a decision by the people who make browsers, not by Brother and not by us. Nothing here can reach one.

Handheld label makers β€” DYMO LetraTag 100H, LabelManager 160, Brother PT-H110
Details

No, and there is nothing to try. These have a keyboard, a small screen and a tape cartridge, and no way of being connected to a computer or a phone at all. They are their own little machines, and good ones β€” just not ones anything here can send a label to.

App-only label makers β€” DYMO LetraTag 200B, Brother PT-N25BT, P-touch Cube, SUPVAN T50M Pro
Details

No. These connect over Bluetooth, but only to the maker own phone app, in a private language nobody has published. The P-touch Cube is a step worse: it uses an older kind of Bluetooth that browsers have no way of opening whatsoever, so even a published language would not help. Nothing here can reach one.

Shipping label printers β€” MUNBYN and Nelko 4Γ—6, Zebra ZSB
Details

Through the ordinary print dialog, yes, like any printer your computer already knows about. Not directly, yet. The MUNBYN and Nelko printers each speak their own language and neither is published per model, so there is nothing to build against without one in hand β€” if you own one, that is a solvable problem. The Zebra ZSB is different: despite the name it does not understand the usual Zebra language at all, and is built to be printed to from your phone or computer rather than by an app, so the print dialog is the way in and always will be.

Honeywell, SATO, TSC, Epson, Godex, Citizen, Bixolon
Details

Researched and not built. Each speaks its own language and most need software on the computer that a browser cannot reach. All of them print through the ordinary print dialog, which is how most people will use them.

Label rolls

The sizes RobCo Depot knows how to lay out, with what the standard layout puts on each. A small roll has room for the QR code and nothing beside it; a large one has room for a name you can read across a room. Those columns describe the layout you get without doing anything β€” a label you design yourself may carry whatever you draw on it, on any roll here. "Checked" means a label of that size was printed and looked at on paper.

Scanners and tags

Four ways a code gets into RobCo Depot, and one that is never coming. You do not need any of them to start β€” there is a box you can type a code into on every screen that reads one.

Scanners and tags
What it is Status Camera USB NFC
The camera on a paired phone
Details

The main way to scan, and the one that needs no extra hardware at all. It reads QR codes and ordinary product barcodes. Some browsers do this themselves and the rest fall back to a reader RobCo Depot loads for them, so it works far more widely than the NFC part does.

Checked Reads a barcode with a camera: Yes Read directly over USB by the browser: No Reads and writes NFC tags: No
NFC tags
Details

Any rewritable NFC Forum Type 2 tag β€” NTAG213 is the common cheap one and is more than big enough; a bigger tag buys nothing. Buy them unlocked. Tapping one is Android-only, so a shelf with a tag should carry the printed label too. Take the phone off the tag once the screen changes: left lying on it, the phone reads the tag for itself and puts its own tag screen over the app.

Checked Reads a barcode with a camera: No Read directly over USB by the browser: No Reads and writes NFC tags: Yes
A USB handheld scanner
Details

Switch it out of keyboard mode β€” its booklet has a barcode for HID-POS or virtual COM β€” and the browser reads the device itself, so scanning anywhere in RobCo Depot opens the record. Connect it once under Profile. Buy one that reads 2D codes, often sold as an imager: the labels RobCo Depot prints are QR codes, and the row below is what a model that reads stripes only will do instead. Scanners do not all wrap a barcode the same way, so a device may need checking against the raw bytes that page shows; that is why this is marked as still settling.

The Netum C750 handheld scanner
Details

A named model rather than a general answer: this one has been run in both of the modes the row above describes β€” HID-POS and virtual COM β€” and read correctly through each, the striped barcodes on packaging and the QR codes RobCo Depot prints alike. HID-POS is the one to reach for first, because nothing has to be installed on the computer for it. Connect it once under Profile and every page on that computer reads what it scans.

Checked Reads a barcode with a camera: No Read directly over USB by the browser: Yes Reads and writes NFC tags: No
A laser scanner that reads striped barcodes only
Details

The cheaper kind of handheld, and the thing to check before buying one: a red line of light reads the striped barcodes on packaging and nothing else. Every label RobCo Depot prints is a QR code, which is a square rather than a line, so a laser reads your deliveries and never your own shelves. No setting changes that β€” it is what the optics can see β€” so look for 2D, QR or imager on the box. Connecting one works exactly as the rows above describe, and half a scanner is still worth having if it is the half you needed.

Details

One paired to your computer arrives as a keyboard, and a keyboard is the one thing no browser may read β€” see the row below. If it came with a USB dongle you can switch to HID-POS, it counts as the USB kind above instead.

A webcam on a computer
Details

The camera scanner on a computer uses whatever webcam is attached, which is how you point a laptop at a pairing code. It has had far less use than a phone camera β€” a webcam is usually further from the label and worse in poor light.

Not checked Reads a barcode with a camera: Yes Read directly over USB by the browser: No Reads and writes NFC tags: No
A scanner left in keyboard mode
Details

This is how every handheld arrives, and RobCo Depot cannot read one. Browsers deliberately refuse to let any web page touch something presenting itself as a keyboard, which is what stops a website logging what you type β€” so this is a rule worth having, not a gap to work around. Scan the mode barcode in the booklet that came with your scanner and it becomes the USB kind above.

The same software as an Android phone, so the same things should work β€” a tablet is simply a large one. Not confirmed here, and a tablet is an awkward thing to scan a low shelf with.

Scanning with the camera works, and so does asking for a label. Tapping an NFC tag does not: Apple has never made that available to web pages, and no browser you install can add it. Print the labels and scan those β€” every feature works that way.

Exactly as an iPhone, for the same reason: camera scanning and printing yes, tapping tags no. The larger screen makes the browsing screens easier and the scanning more awkward.

Browsers on a phone or tablet

No phone browser can print a label directly, whichever one you choose. The printing service listens on its own computer, and a phone has none to listen on β€” so a phone asks a computer to print instead, and the label comes out there.

The only combination where every phone feature works, tags included. If you want to tap a shelf instead of pointing a camera at it, this is the one. It needs the page served over https, which any normal installation is.

Camera scanning, browsing, stock moves and asking for a label all work. Tags do not, and this is Apple's decision rather than a setting β€” see the iPhone row above. The camera lamp is out of reach for the same reason: the phone has one, and no web page on an iPhone may switch it on.

No desktop browser can read an NFC tag, on any operating system β€” the tag part of the web is built for Android phones and exists nowhere else. Everything else on a computer works, including printing straight to a label printer plugged into it.

The app works. Printing without the dialog is the part to watch: it talks to a small service on your own computer over a certificate that browsers do not trust by default, and Firefox keeps its own list of what it trusts rather than using the system one β€” so you may have to accept that certificate in Firefox separately. If it will not, the ordinary print dialog still prints the same label. Pasting a screenshot into a photo field was confirmed on Windows.

Missing, or wrong?

This list only grows by somebody actually trying something. If you have hardware that is not here, or a row that turns out to be wrong on your setup, say so and it will be corrected β€” an entry marked as checked is a claim we would rather fix than defend.
