What Meridian Systems runs on, and why

Meridian Systems works with any networked Zebra label printer, any modern Android tablet and any scanner that types what it reads. 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.

If you already run Label Logic, you may need very little. The printer and the tablet are the same models. What changes is the label stock and the addition of a scanner — a warehouse item gets a code of its own, and somebody has to read it back.

Printers

Zebra ZD621d

What we recommend
300 dpi · direct thermal · 4″ print width · Ethernet + WiFi + Bluetooth · ZD6A043-D01L01EZ

The same printer Label Logic uses. It is a four-inch machine — 4.27″ of usable print width — so it handles a warehouse label and a garment tag equally well. Only the roll changes.

Why the width matters here: a Meridian Systems code is longer than a price tag code, because it identifies one physical object rather than a category. Printed at a density a warehouse scanner is comfortable with, the barcode alone is nearly three inches wide. A two-inch printer cannot do it. See Labels for the arithmetic.

Zebra ZD621d — wired now, wireless later

Cheaper route to the same place
ZD6A043-D01F00EZ  +  wireless module P1112640-017A

The wired ZD621 with the radio added afterwards. It is the same part Zebra fits at the factory, so range and performance are identical — you are buying it later, not buying less.

Worth knowing: adding the radio keeps the Ethernet port, so you end up with both. In a warehouse that is genuinely useful — racking is metal and WiFi can be patchy at the far end of a building, so being able to fall back to a cable at a fixed receiving bench is worth having.

Labels

4″ × 2″ direct thermal

The size we build to

Four inches wide gives the barcode the room it needs at a density that scans across a bench rather than under someone's nose. Two inches of height carries the code, the category, where it came from, when it arrived and who received it.

Why not the Label Logic tag: an item code is 26 characters. In Code 128 that is 286 modules including quiet zones. At 300 dpi:

Bar widthBarcode width
6.7 mil1.91″Fits a small tag, too fine for a warehouse
10 mil2.86″The warehouse standard — what we build to
13.3 mil3.81″Reads across an aisle, no room left for text

Label Logic's tag is 2.25″ wide. A 10 mil barcode needs 2.86″. It does not fit, and dropping the density to make it fit gives you a label that argues with your scanner every time somebody is in a hurry.

On direct thermal: no ribbon means one less consumable to run out of mid-shift, which is the right trade for a receiving bench. But direct thermal fades — figure on months rather than years, and less near heat, sunlight or anything that rubs. If your stock sits in racking for a year before it moves, tell us before you order a case and we will talk you through the more durable stock.

Tablets

Samsung Galaxy Tab A11+

What we test on
11″ · Android · around $250

The same tablet Label Logic runs on, so there is one device to learn, one to buy and one to support across both products.

Why this one: Samsung commits to seven years of security updates. A tablet that stops being patched eventually cannot make a secure connection at all, and becomes a paperweight. Eleven inches is also the right size for reading a location at a glance across a bench.

A case and a screen protector

Not optional in a warehouse

A rugged case such as the SUPCASE UB Pro or Poetic equivalent, both made for this exact tablet. Kickstand for the bench, port covers on the Poetic for dust.

Why we insist: a warehouse floor is concrete. Dropping an uncased tablet onto it once costs more than casing every tablet you own. This is the cheapest insurance in the whole list.

One thing people get wrong: most rugged cases include a built-in screen protector. Do not fit tempered glass underneath one — it lifts at the edges and creates dead spots in the touchscreen. Use the case's own protector, or choose a case without one and fit glass. Not both.

What a case cannot fix: gloves. This tablet does not have the high-sensitivity touch layer that rugged models use, so thick gloves will not register. Capacitive-tipped gloves or a stylus solve it for a few dollars — but decide before your first shift, not during it.

Scanners

Zebra DS2278

What we recommend
cordless · Bluetooth · 1D / 2D / QR · charging cradle

A handheld cordless imager that pairs to the tablet over Bluetooth and works out of the box. Scan the barcode on the cradle and it is paired — one step, no setup screen.

Why cordless and separate, rather than a tablet with a scanner built in: with a built-in scanner you lift an eleven-inch tablet up to every item you scan. With a handheld, the scanner is in your hand and the tablet stays on the bench where you can read it. It is also cheaper to replace one when it is dropped.

Why it needs no software: it pairs as a keyboard. The barcode arrives in the app as if somebody typed it, so there is nothing to install, no driver and no configuration. Roughly 33 ft of range and a 14-hour battery, which covers a shift.

Do you need 2D? Our labels are Code 128, which is a 1D barcode, so a cheaper 1D-only scanner will read them today. We still suggest 2D: it costs little more, it reads QR codes on inbound paperwork, and it leaves the door open if you ever want a denser code on a smaller label.

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 benches 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.
