COMPETITION 2019 - Mini Thermal Printers

[Kitty Hello]

Folks, I'm so amazed about my new gadget. A thermal printer (see attached image).

I've got GLBasic code running, that can send a sprite image to that printer via bluetooth on your Android device. (You can use the BT library to talk to any bluetooth device, btw.)

For the competition you get a few functions in a library and this test project:

Code: (glbasic) [Select]

LOADSPRITE "Media/test.png", 101

LOCAL printer_pixels_width% = 384 // must be editable by user. Default = 384
DitherSprite(101, printer_pixels_width) // id%, cut_width%

// Show the dithered image - you can save or use that for debugging/preview
DRAWSPRITE 101,0,32
SHOWSCREEN


// List all paired BT devices - user must pick one from the list
LOCAL devs$[]
BT_ListDevices(devs$[])

// connect to one of the string in devs$[]
BT_connect("BlueTooth Printer")

// do print the image pixels
BT_print_image(101)

// close connection
BT_close()

// some more paper and cut (if device lets you do this)
BT_FeedPaperAndCut()

MOUSEWAIT

You will also get a function to pick a picture from camera or from the gallery.

The BlueTooth-Library attached is cross-platform and can talk to any BlueTooth device with raw data streams.



That's all you need. Now join the competition and write a software for that printer with the given functions. A demo project is attached. It might not compile for Android, but the function names wil stay as they are. I did tests and all is working great. Ready? Set? GO!

Do samething amazing. Something creative. Something funny. Something that makes one want to get such a printer.

The 1st prize is such a printer. Shiny new device, sparkling on your table, purring in your pocket.
2nd to 3rd price: Printer paper

Competition ends at March, 1st 2019.

PS.Spread the word - I'm not very connected in social media anymore 

Edit - See my test project and the final libraries attached.

This is great! I wanted to do thermal printer before using GLB.

So GLB 'can' print

[Ian Price]

Sounds cool

[bigsofty]

Aha, I had a similar device when I was a boy for my ZXSpectrum. It printed on shiny silver paper and made a lot of noise. It was great fun, though it made your fingers silver too from the weird paper it used. 

[MrPlow]

Can the same be done to send from Desktop to printer via BT or USB?

[erico]

I´m cracking my head on how to mix this all with a game.

[Kitty Hello]

The code also works on Desktop now, yes.

[MrPlow]

WTF! really niiiice!

[MrPlow]

The code also works on Desktop now, yes.

Hi _ I downloaded the sample but it says Android_javacall function not found...I am missing something?
Also - for desktop - windows - surely javacall is not used?

[Kitty Hello]

I'll soon update the code. It will compile on V16 (lots of compiler imporvements were required)

Hi
On v16 compiling the Thermal printer code
"BluetoothAndroid.gbas"(67) error : GPC0006 wrong number of aguments : "android_JAVACALL" called with 2 args. Required: 0 to 1

(also tiny misspelling - aguments)

Will be possible get data from the devices?¿.... With Bluetooh HC-05 and arduino works.

[Qedo]

 can not open bluetooth.zip. CRC error.
Could you verify?
Thank you

[Moru]

Yes, it's damaged but I think you can find the file in your samples folder (GLBasic\Samples\_Projects_\Bluetooth.zip)

[Qedo]

Perfect.
Thank you
