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.

(Here for B4J, Here for B4A)

This version requires an activation code. If you do not have a code then it will work in DEMO mode and you will only be able to print every 4 minutes.

Sample:

Code:

Private Sub Application_Start (Nav As NavigationController)
    'SetDebugAutoFlushLogs(True) 'Uncomment if program crashes before all logs are printed.
    NavControl = Nav
    Page1.Initialize("Page1")
    Page1.Title = "Page 1"
    Page1.RootPanel.Color = Colors.White
    NavControl.ShowPage(Page1)
    Page1.RootPanel.LoadLayout("Layout1")
    
    Ble.Initialize(Me,"Ble","")
    ButtonSend.Visible=False
    ButtonImage.Visible=False
End Sub

METHOD

Code:

Sub ButtonScan_Click
    Ble.ScanPrinter
    ButtonSend.Visible=False
    ButtonImage.Visible=False
End Sub

Sub ButtonSend_Click
    Ble.Writeline(ESC_POS.DoubleOn & "TEST OF PRINT")
End Sub

EVENT

Code:

Sub Ble_PrinterFound(Name As String, ID As String)
    LabelInfo.Text=$"Fondi printer: ${Name}"$
    Ble.connect(ID)
End Sub

Sub Ble_Connected(services As List)
    ButtonSend.Visible=True
    ButtonImage.Visible=True
End Sub

Sub Ble_Disconnected
    ButtonSend.Visible=False
    ButtonImage.Visible=False
End Sub

 

What’s the donation amount ?

 

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*

 

Ignore it, it's not working yet

 

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

 

Good work. Just continue your quest. Good luck...

 

I tried the current version. It(s not compiling.

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

 

Any clue ?

 

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

 

Good luck with your present project. Looking forward to see you back on iOS. Such a library is needed.
