Why the ZD621

4-inch labels at up to 8 ips, Ethernet built in

The ZD621 is the 4-inch model in Zebra's ZD600 Series, alongside the 2-inch ZD611. It runs Link-OS and comes in direct thermal and thermal transfer versions, with a healthcare model (ZD621-HC), an RFID model (ZD621R) and a linerless option.

8 ips with Ethernet and serial built in

Up to 203 mm/s (8 ips) at 203 dpi and 152 mm/s (6 ips) at 300 dpi. Ethernet 10/100, RS-232 serial, USB 2.0 and USB Host are standard, so no add-on module is needed to put it on a wired network or a serial host.

Wi-Fi when you need it

Zebra offers a dual-radio Wi-Fi 6 (802.11ax) with Bluetooth 5.3 module, factory fitted or field installable, and a Wi-Fi 5 (802.11ac) with Bluetooth 4.2 module. Bluetooth Low Energy for the setup app is built in.

Colour touch display

An optional 4.3-inch colour touch LCD (480 × 272) with 3 buttons lets staff change settings without a PC. It is standard on the healthcare models; the other models have 5 status icons and 3 buttons.

Keeps your label formats

It runs ZPL II and EPL 2, the languages of GX420, ZD500 and ZD620 fleets, plus XML, ZBI and PDF Direct. EPL1 line mode is available on the 203 dpi direct thermal model.

RFID model

The ZD621R encodes UHF EPC Gen 2 V2.1 tags with Zebra's RE40 encoder, at a minimum tag pitch of 16 mm.

Wide range of media

Rolls up to 127 mm outside diameter on 12.7 mm or 25.4 mm cores (38.1, 50.8 and 76.2 mm with adapters). Labels, tags, receipt paper, wristbands and linerless labels, with a field-fit peeler or cutter.

Used in

  • Retail and FMCG packing (MRP and shelf labels)
  • Warehousing, 3PL and e-commerce
  • Courier and last-mile dispatch
  • Electronics (EMS) and auto-component plants (300 dpi serial-number and component labels)
  • Ticketing and event wristbands

For buyers in India

Using the ZD621 in India

These are the points buyers in India ask us about the ZD621. Mention the ones that apply to you when you request a quote.

Runs on 230 V Indian mains; stabilise where it swings

The ZD621 runs on India's 50 Hz single-phase supply without a converter, but where the voltage swings often, run it through a stabiliser or UPS. Its external power supply is auto-detecting, rated 100-240 VAC at 50-60 Hz.

Keep it air-conditioned from March to June

From March to June, keep the ZD621 in an air-conditioned room. Zebra rates it to operate from 4.4 °C to 41 °C and to be stored up to 60 °C.

Bring printer and rolls to room temperature first

In humid coastal cities such as Chennai and Mumbai, let the ZD621 and its label rolls reach room temperature before printing. The risk is condensation: a printer or label roll moved from an air-conditioned store into a humid loading dock can collect moisture. Operating humidity is rated 10-90% and storage 5-95%, both non-condensing.

A 4 × 6 inch courier label in about 0.75 s at 203 dpi

At 203 mm/s (8 ips), the ZD621 needs about 0.75 seconds of print time for each 4 × 6 inch courier label. So 100 courier labels take about 75 seconds of print time. The label (101.6 × 152.4 mm) fits the 104 mm print width at 203 dpi.

MRP text and GS1 India barcodes; ribbon for rough handling

The ZD621 prints MRP and net-quantity text with GS1 India barcodes; for packs that face rough handling, use the thermal transfer model with a ribbon. It prints EAN-13 (GS1 India numbers start with 890), UCC/EAN-128 (GS1-128), GS1 DataBar, Data Matrix and QR Code. Ask us to set up your label format and print test labels on your roll.

300 dpi for small electronics labels; 600 dpi ZT610 for shorter ones

We supply the 300 dpi ZD621 to electronics manufacturing services (EMS) customers. It suits serial-number, product ID and component labels at a desk: it prints 12 dots per mm, takes labels from 6.4 mm long (12.7 mm with the peeler or cutter) and media from 15 mm wide, and prints Data Matrix codes. For labels shorter than that, or PCB labels on a production line, choose the 600 dpi ZT610: it prints labels as short as 3 mm in rewind or tear-off mode, and its Micro Label Printer version peels labels down to 6 mm (Zebra's US tech specs). Ask us to print test labels on your material before you order.

Exploring for a different use?

If your job differs from what the ZD621 is built for, these Zebra models may fit it better:

  • Buyers who print a moderate number of 4-inch labels and can add the network later often look at the Zebra ZD421 (up to 152 mm/s (6 ips); Ethernet and Wi-Fi fit in the field).
  • Buyers who only print labels 56 mm wide or narrower often look at the Zebra ZD611 (2-inch, up to 203 mm/s (8 ips), Ethernet built in).

Questions buyers ask

ZD621 FAQ

What is the price of the Zebra ZD621 in India?

The ZD621 price depends on the resolution you choose (203 or 300 dpi), the options you add and the quantity. We can quote the labels and ribbon with it. Ask our team for today's competitive price: share your requirement and budget, and we will help you choose the right configuration and send a written quotation with current pricing and delivery time.

We have a ZD620, ZD500 or GX420. Is the ZD621 the replacement?

Yes. Zebra's support pages show that support for the ZD620, ZD500 and GX420/GX430 ended on 28 February 2025 in Asia-Pacific, and Zebra names the ZD621 as their successor. It keeps the 4-inch width and Zebra's ZPL and EPL languages, so most label formats carry over. Include one of your current labels when you ask for a quote.

ZD621 or ZD421: which should we choose?

Both are 4-inch Zebra desktops at 203 or 300 dpi. The ZD621 prints at up to 203 mm/s (8 ips) against 152 mm/s (6 ips), and has Ethernet and RS-232 serial built in; on the ZD421 these are add-on modules. The ZD621 also offers a colour touch display and an RFID model. The ZD421 suits a counter that prints a moderate number of labels.

Can the ZD621 print 4 × 6 inch shipping labels for couriers and marketplaces?

Yes. A 4 × 6 inch label is about 102 mm wide and 152 mm long. The direct thermal ZD621 takes media from 15 mm to 108 mm wide (118 mm on the thermal transfer model), prints up to 104 mm wide at 203 dpi and handles labels up to 991 mm long. Direct thermal needs no ribbon, and rolls up to 127 mm outside diameter fit inside the printer.

Is there an RFID version of the ZD621?

Yes. The ZD621R adds Zebra's RE40 UHF RFID encoder for EPC Gen 2 V2.1 tags, with a minimum tag pitch of 16 mm. On the ZD621R the 4.3-inch colour touch display is optional.

Does the ZD621 work over Wi-Fi?

The standard printer has Ethernet 10/100, RS-232 serial, USB 2.0 and USB Host, plus Bluetooth Low Energy for Zebra's setup app. For Wi-Fi, Zebra offers a dual-radio Wi-Fi 6 with Bluetooth 5.3 module, factory fitted or field installable, and a Wi-Fi 5 with Bluetooth 4.2 module. A printer bought for Ethernet today can take Wi-Fi later.

Can Allmark install the ZD621 and connect it to our software?

Yes. We install the ZD621 at your site, connect it so your ERP, warehouse or billing software prints to it (our own warehouse management system included) and train the people who use it. Tell us the software when you ask for a quote, and we include the setup in the quotation.
