Do you want to build your own wireless thermal printer, that you can print to from your Mac, PC, Phone or Tablet? Then watch this video.
We'll go through all the bits and pieces you need, along with how to setup the Raspberry Pi Zero so that it can share the printer on your local network.
This is loads of fun and very cheap for a printer too.

Great Sir

hey i've done all this and all that I get when I print the test print is hundreds of 'a' character. I noticed that the firmware for my printer is SV1, not GV2 as it says in the Adafruit tutorial, do you know if this is the issue and of any extra steps required to get this version to work?

@the4kidstvshow Год назад

Wow!

@DasInnereDesBrotes 2 года назад

cool project! But as most thermal recipe printers got an ethernet port, isnt it a bit doubled? What I really would love is a bluetooth printer version. I was trying really hard the last two days to set up a zero w as bluetooth server, but it rejects working :(

@ArnauNau Год назад

You could try using an HC-05/HC-06 chip which enables serial communication via Bluetooth (the way I use it is I connect my laptop to the chip from Bluetooth settings and treat that Bluetooth channel as a serial port, which it is). You may need to adjust the chip’s configuration the first time but it’s not hard.

@ArnauNau Год назад

This would only work as a way to have your rpi connected to the printer by Bluetooth though, not to let random (non-set-up) phones and laptops print directly to the printer since the Bluetooth connection is only a serial connection over the air

@williamwatkins6669 2 года назад

Have you done anything for the printer to print smoothly? Mine stutters and does not print continuously. I have it on a large power supply so voltage is not the issue

@kevinmcaleer28 2 года назад

Is it a baud rate thing?

@williamwatkins6669 2 года назад

@@kevinmcaleer28 I don't think so. The test page shows 19200 and that's what I used. Using a different one leads to gibberish being printed What is the gv2 version on your test page?

@shimongorodetsky7790 2 года назад

can i use different type or raspery pi ?

@kevinmcaleer28 2 года назад

Sure can! It’s just serial so you can connect any single board computer that can run Linux

Is this the adafruit printer? (£40 from Pimoroni)

@kevinmcaleer28 2 года назад

I think it is from Adafruit / Pimoroni

@xcugasteam489 2 года назад

For me, thermal printer printing random character. Whhat should I do?

@kevinmcaleer28 2 года назад

First off, check the baud rate, needs to be right for the printer (hold down the button on the printer when applying power will print a status page with the right baud rate). Next check the serial pins your using are not being used as console out by the pi zero. Finally I’ve heard putting a few low value resistors between each rx/ tx connection can stop the lines from floating and giving spurious results

@ChristinaSmith 2 года назад

I am having that same issue. Did you ever get it to work?

@ChristinaSmith 2 года назад

@@kevinmcaleer28 I am having the same issue of it printing gibberish when I try to to the test print. It functions correctly, has the correct baud rate, and can do the self test just fine. Anything else is garbage though. What size resistors do you suggest for the TX and RX wires? That's the only thing I've not tried yet.

@@ChristinaSmith can you tell me a bit more about your setup, what version of software your using - I did have something similar with the software that converts images behind the scenes not handling the conversion properly
