How to Choose a Thermal Printer for Billing: 58 mm vs 80 mm and More
A thermal printer prints with heat on special paper, needs no ink, and prints a bill in a second or two. Most counter bills in India come off one. Choosing well comes down to five questions: paper width, how it connects, whether it cuts, whether your software can drive it, and what paper you will feed it.
Key takeaways
- 80 mm suits busy counters and bills with many lines; 58 mm suits small shops and portable use.
- Match the connection to where you bill: USB for a PC, Bluetooth for a phone, network for several counters or a kitchen.
- An auto-cutter saves time at a busy counter.
- Thermal paper fades; keep digital copies of bills for the record-keeping period.
58 mm or 80 mm
| 58 mm | 80 mm | |
|---|---|---|
| Characters per line | Fewer; long item names wrap | More; columns fit more comfortably |
| Good for | Small shops, food stalls, portable billing | Supermarkets, restaurants, pharmacies, GST bills with HSN and tax columns |
| Size and cost | Smaller and usually cheaper | Larger, often faster, often with a cutter |
| Paper rolls | 58 mm rolls | 80 mm rolls |
Connection
- USB: simplest for a Windows billing PC; set up once with the driver
- Bluetooth: pairs with an Android phone or tablet; good for small counters and delivery
- Network (LAN or Wi-Fi): several counters or devices can share one printer; the usual choice for kitchen order printers
- Some printers offer two connections, which helps if you move from phone to PC later
Other things to check
- Auto-cutter: cuts the bill cleanly; worth it above a few dozen bills a day
- ESC/POS command support: the common standard most billing software can drive
- Print speed: matters at peak hours more than the brochure figure suggests
- Cash drawer port: lets the printer open the drawer when a cash bill prints
- Local service and spare parts: a dead printer stops the counter
- Indian-language printing: if you print item names in Kannada, Hindi or another script, test it with your software before buying
Rules that apply to the bill, not the printer
| Requirement | What to check on a narrow roll |
|---|---|
| GST tax invoice fields | Your GSTIN, invoice number and date, HSN, taxable value, tax rate and amounts, and place of supply must all print legibly |
| Buyer details for larger B2C bills | For bills of ₹50,000 or more to unregistered buyers, name, address and delivery address must appear |
| FSSAI number for food businesses | Food businesses print their FSSAI licence or registration number on bills |
| Keeping records | Thermal prints fade; GST requires records to be kept until 72 months after the due date of the annual return, so keep the bills digitally |
Checked on 11 November 2026 against CGST Rules 46 and 56, CGST Act section 36 and FSSAI's order on licence numbers on bills.
Paper
Buy thermal rolls of the right width and the core size your printer takes, from a supplier you trust. Poor paper prints faint, fades fast and wears the print head. Store rolls away from heat and sunlight. If customers need bills they can keep, such as warranty bills for phones, also share a PDF or link.
Setting up
- 1Install the driver or pair the printer, and print the self-test page.
- 2Select the paper width in your billing software's print settings.
- 3Print a sample GST bill with your longest item name and check every field is readable.
- 4For restaurants, name each kitchen printer and map it to its station.
- 5Keep a spare roll at every counter and note who reorders paper.
Where TripleBill fits
TripleBill prints 58 mm and 80 mm thermal receipts from the counter, and every bill can also be shared as a link or PDF. On the Windows app you can type each kitchen station's printer name so KOTs print there without a dialog. It works with printers your device can already print to; check your model with a test bill before buying in bulk.
Frequently asked questions
Should I buy a 58 mm or 80 mm printer?
80 mm for busy counters and detailed GST bills; 58 mm for small shops and portable billing.

Do I need a separate printer for the kitchen?
For a restaurant, yes, usually a network printer at each station, or a kitchen screen instead.
