I am using a Zebra iMZ320 printer, a windows mobile device, CPCL and vb.net.
I am trying to get the code to load a bitmap image and then to print this using CPCL
I have previoulsy had a similar piece of code to that contaibed below working with no issue. I must be missing something obvious, but for the life of me I cannot see it.
My problem is the printer will only printout HEX instead of the image ! Has anyone come across this before ? Can you help ?
Public Sub DrawBitmap(ByVal xPosition As Integer, ByVal yPosition As Integer)
Dim bmp As Bitmap bmp = New System.Drawing.Bitmap(GetLogo)
If bmp Is Nothing Then
Throw New ArgumentNullException("bmp")
End If
'Make sure the width is divisible by 8
Dim loopWidth As Integer = 8 - (bmp.Width Mod 8)
If loopWidth = 8 Then
loopWidth = bmp.Width
Else
loopWidth += bmp.Width
End If
cpclData = ""
cpclData = cpclData & "! 0 200 200 300 1 " & vbCr & vbLf
cpclData = cpclData & (String.Format("EG {0} {1} {2} {3} ", loopWidth \ 8, bmp.Height, xPosition, yPosition))
For y As Integer = 0 To bmp.Height - 1
Dim bit As Integer = 128
Dim currentValue As Integer = 0
For x As Integer = 0 To loopWidth - 1
Dim intensity As Integer
If x < bmp.Width Then
Dim color As Color = bmp.GetPixel(x, y)
Dim MyR As Integer = color.R
Dim MyG As Integer = color.G
Dim MyB As Integer = color.B
intensity = 255 - ((MyR + MyG + MyB) / 3)
Else
intensity = 0
End If
If intensity >= 128 Then
currentValue = currentValue Or bit
End If
bit = bit >> 1
If bit = 0 Then
cpclData = cpclData & (currentValue.ToString("X2"))
bit = 128
currentValue = 0
End If
'x
Next
Next
'y
cpclData = cpclData & vbCr & vbLf
cpclData = cpclData & "PRINT"
Print_Invoice()
End Sub
Public Shared Function StrToByteArray(ByVal str As String) As Byte()
Dim encoding As New System.Text.ASCIIEncoding()
Return encoding.GetBytes(str)
End Function
Private Sub Print_Invoice()
' Instantiate a connection
Dim thePrinterConn As ZebraPrinterConnection = New BluetoothPrinterConnection(MyMacAddress)
' Open the connection - physical connection is established here.
thePrinterConn.Open()
' Send the data to the printer as a byte array
thePrinterConn.Write(StrToByteArray(cpclData))
' Make sure the data got to the printer before closing the connection
Thread.Sleep(500)
' Close the connection to release resources.
thePrinterConn.Close()
' Debug output
txt_TestPrint.Text = cpclData.ToString
Dim objStreamWriter As StreamWriter
Dim file_name As String
'open dialog box for new file
SaveFileDialog1.InitialDirectory = "\Storage Card\"
If SaveFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
file_name = SaveFileDialog1.FileName
If Len(file_name) > 0 Then
objStreamWriter = New StreamWriter(file_name & ".txt")
'Write a line of text from list box.
objStreamWriter.WriteLine(txt_TestPrint.Text)
'Close the file.
objStreamWriter.Close()
Exit Sub
End If
End If
End Sub
The code produce this file as output if it helps.
