Label Logic works with any networked Zebra label printer and any modern Android tablet. You are not locked to a list. But people ask what we actually use, so here it is, with the reasoning rather than just the part numbers.
Printers
Both print the same tag and set up the same way. The app talks to a printer at an address on your network and cannot tell how it got there, so wired and wireless are genuinely interchangeable — buy for the building, not for the software.
Zebra ZD621d
What we recommendEthernet and WiFi in one printer, in the box. Plug in a cable where that is easy, leave it on WiFi where it is not, and decide when you install it rather than when you order it.
Why this one: every store is a different building, and this is the one that works in all of them. It also has an industrial-grade mechanism, an eight-inch roll capacity and a faster print engine than the ZD421 — the difference between a printer built for a production line and one built for a shipping desk. At 300 dpi small text on a garment tag is crisp rather than merely legible.
Zebra ZD621d — wired now, wireless later
Cheaper route to the same placeThe wired ZD621 with the wireless card added afterwards. Zebra fits the same radio at the factory on the dual model, so the range and performance are the same either way — you are buying the identical part, just later.
Why bother: the module usually costs less than the factory dual option, so if you are confident a store will be wired, you can start cheaper and keep the door open. Nothing is lost if you never fit it.
What it costs you: somebody has to open the printer and seat the card. That is a ten-minute job if you are doing it yourself and a phone call if you are talking someone else through it. For a printer going to a store you cannot walk into, the dual model is usually worth the difference.
Zebra ZD421d
Lower budgetNoticeably cheaper. A sensible second station, or a store tagging a few dozen items a day.
You are not locked in. There is no ZD421 with both in the box, but adding the wireless module to a wired one keeps the Ethernet port — you end up with both, confirmed by Zebra. So buy for the building you have and change your mind later if you need to. The module is P1112640-017A, the same part that upgrades the ZD621d.
What you give up against the ZD621: it is slower, the mechanism is lighter duty and the roll capacity smaller, so you change rolls more often. On a heavy intake day you will feel it. Zebra positions it for offices and light retail rather than a production line.
Avoid the 203 dpi version. Cheaper still, but the tag layout has to be re-done for it and small text comes out coarser. If you want one anyway, tell us before you buy so we can make it print correctly.
The tablet never needs a cable. It can sit on WiFi and print to a wired printer perfectly well. The only requirement is that both lead back to the same router — and not a guest network, which is walled off from everything else by design.
Labels
2.25″ × 1.37″ direct thermal
The size we build toTwo kinds, one size: perforated tag stock for hang tags, and adhesive labels for stickers. Both run on the same printer model, and the tag layout is identical — only the roll changes.
Why direct thermal: no ribbon means one less consumable to run out of mid-shift. Direct thermal fades over months in strong light, which does not matter on an eight-week floor rotation. If your stock sits out much longer than that, ask us and we will talk you through thermal transfer instead.
Tablets
Samsung Galaxy Tab A11+
What we test onAny modern Android tablet works. This is the one our own testing runs on.
Why this one: Samsung commits to seven years of security updates on it. That matters more than it sounds — a tablet that stops being patched eventually cannot make a secure connection at all, and becomes a paperweight. Seven years means you never have that conversation. Eleven inches is also the right size for a grid of category buttons; eight-inch screens are harder to hit accurately at speed.
Scanners
Handheld barcode scanners
Coming with Meridian SystemsLabel Logic does not need a scanner — it prints tags, and your register reads them. Scanners are for Meridian Systems, our warehouse receiving software, which is still in development.
When it arrives: most warehouse scanners are keyboard-wedge devices that simply type the barcode, so they work without drivers or setup. We will publish specific recommendations once Meridian Systems is ready.
Ordering
Buy the hardware wherever you like — any Zebra reseller stocks these, and we take nothing from anyone who sells them.
If you would rather not work it out yourself, email support@meridian-technologies.net with how many stores and stations you are setting up, and we will send back a specific list with part numbers so you can hand it to a supplier.
Tell us what you have bought before it arrives and we will have it configured and tested by the time you plug it in.
