## Pricing

- **Price:** $96.40 (inc GST) — $87.64 AUD, exc GST
- **Quantity discounts:** 10+ $85.01 (exc GST) · 50+ $83.25 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2753:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA2753:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Add printing capability to any microcontroller project with **just the innards of a thermal printer.** Thermal printers are also known as receipt printers, they're what you get when you go to the ATM or grocery store. Now you can embed a little printer of your own into a custom enclosure of your choosing. This printer is ideal for interfacing with a microcontroller, you simply need a 3.3V-5V TTL serial output from your microcontroller to print text, barcodes, bitmap graphics, even a QR code!

This is the super hackable version! All that's included is the guts of a thermal printer: the motor/heater with a flex cable and a control board with a chip that will take your serial commands and use them to drive the motor & heater. You also get a TTL cable and a 33' roll of thermal paper. You'll likely want to design some sort of enclosure for it, especially since its a little challenging to line up the paper so it feeds through straight. That said, because there's no paper bay you can use as little or as much paper as you like, heck you can even feed in a mobius strip!

Adafruit really like this printer because its easy to make **Bold,** underline,  inverted text, variable line spacing, left/center/right justification, barcodes in 11 standard formats with adjustable height, and even **custom bitmap graphics.**

Of course, Adafruit wouldn't leave you with a datasheet and a "good luck!" - Adafruit have a full tutorial and matching Arduino library that demonstrates the following:

- Printing with small, medium and large text
- **Bold**  and underline text
- Inverted text
- Variable line spacing
- Left, center and right justification
- Barcodes in the following standard formats: **UPC A, UPC E, EAN13, EAN8, CODE39, I25, CODEBAR, CODE93, CODE128, CODE11** and **MSI** - with adjustable barcode height
- Custom monochrome bitmap graphics!
- How to include a QR code
