B4i Library iSD BLE Printer

I am happy to present my library to print with Iphone (and iPad) with Bluetooh (BLE). At the moment I can not print the images, but I'm working on it. If you want to have the activation code (Freeing all the functions) contact me in private.

(Herefor B4J, Here for B4A)

This version requires an activation code. If you don't have a code, it will work in DEMO mode and you can print for just one minute every 4 minutes.

Dear @jahswani ,
As long as I do not add the images will be free donation, there will not be a minimum limit. When I add the PrintBitmap method, contact me privately, as specified in post # 1

What about this method ?
  • PrintBitmap (bmp As B4IBitmap*, Shift As Int) As NSString*

Finally I managed to print in graphics with BLE. It is a simple chessboard, but that makes the idea of potential.
Even if it is a step forward I am still far from printing an image.

The BLE protocol is giving me a hard time, the packages must be small and the images sectioned to be transmitted .... we'll see if I succeed

Frankly I don't understand what error it is. I'll do some tests

It seems like it’s requesting different parameters on the initialize method. Please check. The method is also difficult in the .a file

I used B4I 5.50 for this library. You are using 4.81, maybe it depends on this because it seems that it doesn't find the initialize method

Star-Dust, congratulations for your effort.

I am considering porting my present Android app to iOS with B4i, but I absolutely need quality printing.

Any idea of the resolution of the printed output ?

Have you completed bitmap printing ? At which practical resolution ?

You may want to add a "fit to paper" option in case the picture is too big.

unfortunately at the moment I did not get a good press, but I suspended temporarily because I have a more urgent project. I will resume soon

I just tested the example attached with B4I 6.80 beta 1, and compile it correctly.
I use the Hoster Builder server.

Report an error on line 12, where there is no instruction and does not affect compilation.
Make sure you've copied the necessary files to the build server. I updated the example, download it and try it.

The .a and .h files must be copied to the Libs Mac folder of the server in order to be able to compile

Usually when you compile a library locally, the server copies the .a and .i files to the Libs Mac folder and they are ready to be compiled within the App. (see here)
Those you download from the forum You must copy them instead.

PS. I don't use Mac but develop on Windows, so for more details on how to use the libraries better than ask the question on the forum
