SapphireIrDA

Printing from your application can be a very useful tool in a situation where you need to give a receipt to your customer direct from your Pocket PC. The ideal solution is to use an IrDA enabled printer with the IrDA port on your device. The Sapphire IrDA Utility allows you to print to such a printer right within your application.

Product Features

The Sapphire IrDA Utility makes infra-red printing easy with the following functionality:

• Establish a connection with a IrDA enabled printer
• Print text to the printer
• Print new lines and form feeds to the printer
• Close the connection to the printer

You can download the latest demo version to see a fully working demo which you can reuse within your application as you see fit. This can be found on the download pages. The demo versions are fully functional and simply contain a popup message from time to time. These are ideal if you are selling your application to the client where you can be confident the application will work in practice and not just theory.

Sample Code

Implementation couldn’t be easier, simply declare the DLL function as a function within your application and call it as though you wrote it yourself. Here’s a sample demo on how to connect to a printer and print a string of text within VB.NET.

Dim iRet As Integer

Dim sLine As String

iRet = prnConnect(SapphireIRDALicence)

If (iRet = 0) Then

  ' Start printing the text

  sLine = "Test print using the SapphireIRDA DLL"

  If (prnPrintLine(sLine, sLine.Length) <> 0) Then

    MsgBox("Failed prnPrintLine")

  End If

End If
