i do not know java,and never use eclipse before, i study make libary 1 week,now have self library now )
i have test this code many times, it is really hardly work for me,
here cannot upload my eclipse project,it is too big,how to upload it ?
if this library can help you ,i will send my eclips project .my java is poor,
if i upload eclips project ,you can make this libary more better then me.


i have test on my pos printer,work good now ,can print picture.string

my print device use default ".connectusb" fuction, if you change print device need ".connectusb2" instead.

and you need get your usb" VendorID , productID"
how to get your print device ID ,here have picture .(do not forget add 0x before your IDs)

the ".printdata"fuction ,you can send HEX code to printer. it is is printer control code.in PDF file have EPSON FAQ, in FAQ,the Turn "white/black reverse "command "1d 42", MUST change to under FORMAT SEND:
"0x1d, 0x42, 0x01". (0x01 must put in end. and add 0x)

In mainfest need add usb permition :
B4X:
AddActivityText(main,
    <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />

    )
under is b4a sample code

B4X:
#Region  Project Attributes
    #ApplicationLabel: B4A Example
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
     #BridgeLogger: True
#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Globals
 
    Dim pt As  printdemo
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("1")
    pt.initialize

End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub


Sub Button1_Click
 
    Dim vid As Int
    Dim pid As Int
    vid=0x1CBE
    pid=0x0003
    pt.connectusb2(vid,pid) 'HERE IS YOU DEVICE VendorID AND productID"
 
End Sub

Sub Button2_Click
    pt.printstr("UNDER IS PICTURE")
 
    pt.printtest  'TEST PAPER
 
 
End Sub

Sub Button3_Click
    Dim pic As Bitmap
 
    pic.Initialize(File.DirAssets,"look.bmp")
 
    pt.printstr("UNDER IS PICTURE")
    pt.Print_BMP2(pt.POSPrintBMP(pic,300,0))   '(PICTURE,PAPER WIDTH,0)
 
 
    Sleep(1000)
 
 
 
    pt.cut    'CUT PAPAR
    pt.Printbeep 'VOICE BEEP
End Sub

I am currently trying to get the following to work with my app.

EPSON TM-T20II VID_04B8, PID_0E15
Excelvan Model: ZJ-5890F VID_0416, PID_5011


1st choice is the EPSON
The 2nd printer (Excelvan) is a cheap printer (arounc $25.00) that I would like to try.

Thanks.

we use a printer Bluetooth, maybe you could get one.
it's really simple. We use in restaurants, without problems.
