Product listings for label printers are full of numbers, and most of them do not matter much for a seller printing Flipkart and Meesho shipping labels. A few matter a lot: get those wrong and the printer either cannot print a full 4×6 label or cannot be set up on your computer. This guide goes through what to check, in order of importance.
We do not recommend specific models, because we have not tested them. Use the checklist at the end to compare the printers you are considering.
1. It must print 4-inch-wide labels
Marketplace shipping labels are made for 4×6 inch (100×150 mm) labels. Some small printers sold as "label printers" are really receipt or barcode printers that only handle 2- or 3-inch-wide paper, and a 4-inch label will not fit.
Look for a maximum print width of at least 4 inches, which listings usually give as about 104 mm or 108 mm. This is the one specification you cannot work around later.
2. Direct thermal is what you want
There are two kinds of thermal printing:
- Direct thermal printers heat special heat-sensitive labels. No ink, toner or ribbon is needed. The print slowly fades over months, especially in heat or sunlight, which does not matter for a parcel that is delivered within days.
- Thermal transfer printers melt ink from a ribbon onto the label. The print lasts for years, which suits product and inventory labels, but you pay for ribbons as well as labels.
For shipping labels, a direct thermal printer is simpler and cheaper to run. Many printers support both modes, which is fine too.
3. 203 dpi is enough
Resolution is given in dots per inch (dpi). 203 dpi is the standard for shipping printers and prints courier barcodes and address text clearly. 300 dpi printers produce sharper small text and suit tiny labels or dense 2D codes, but they cost more and are not needed for 4×6 shipping labels.
4. Check which label rolls fit
Labels come on rolls wound round a cardboard core, or as a folded stack called fanfold. Before buying, check two things in the printer's specifications:
- Core size: commonly 1 inch or 3 inches. The rolls sold by your label supplier need to match.
- Maximum roll diameter: larger rolls mean fewer changes. If the rolls you want are too big for the printer, you can often feed fanfold labels from behind instead.
5. A gap sensor, ideally with auto-calibration
Shipping labels are die-cut: separate labels with a small gap between them on a backing sheet. The printer finds the start of each label with a gap sensor. Almost every label printer has one, but printers with easy or automatic calibration save a lot of frustration when you switch to a roll from a different supplier. Our thermal printer setup guide explains calibration in detail.
6. Drivers for your computer
You will print from a Windows PC or a Mac, so the manufacturer must publish a driver for your operating system. Check the brand's own support page before you buy. A missing or outdated driver is the most common reason a new printer will not show a 4×6 paper size.
7. USB, Bluetooth or Wi-Fi
USB is the simplest and most reliable way to connect, and it is all most sellers at a single desk need. Bluetooth or Wi-Fi is useful if you want to print from a phone or share one printer between several computers. Do not assume every wireless model can print PDFs straight from a phone, though: check that the manufacturer's app supports what you need.
8. Warranty and service in India
The printhead is the part that wears out, and it eventually needs replacing on a busy printer. Prefer a brand with a clear warranty, authorised service in India, and replacement printheads you can actually buy.
What you can mostly ignore
- Print speed. Almost any label printer prints a 4×6 label in a second or two, faster than you can pack.
- Large memory or built-in fonts. These matter for industrial use, not for printing PDFs from a computer.
Checklist before you buy
- Maximum print width of at least 4 inches (about 104 mm or more).
- Supports direct thermal labels.
- 203 dpi or higher.
- Core size and roll diameter match the labels you can buy.
- Gap sensor, preferably with easy or automatic calibration.
- Official driver for your Windows or macOS version.
- The connection you need: USB for one desk, wireless for phones or shared use.
- Warranty and service support in India.
