How to cut paper on POS Printer in Windows 7
My (POS) printer needs to receive the following sequence code "LPRINT CHR$(29); CHR(86); CHR$(48)" in order to activate the
paper cutter at the end of a print report.
In MS Access VBA on Windows7 64bit: goes like this:
Option Compare Database
Private Type DOCINFO
pDocName As String
pOutputFile As String
pDatatype As String
End Type
Private Declare Function ClosePrinter Lib "winspool.drv" (ByVal _
hPrinter As Long) As Long
Private Declare Function EndDocPrinter Lib "winspool.drv" (ByVal _
hPrinter As Long) As Long
Private Declare Function EndPagePrinter Lib "winspool.drv" (ByVal _

Private Declare Function OpenPrinter Lib "winspool.drv" Alias _

Private Declare Function StartDocPrinter Lib "winspool.drv" Alias _
"StartDocPrinterA" (ByVal hPrinter As Long, ByVal Level As Long, _
pDocInfo As DOCINFO) As Long
Private Declare Function StartPagePrinter Lib "winspool.drv" (ByVal _

Dim sWrittenData As String
Dim MyDocInfo As DOCINFO
lReturn = OpenPrinter("XP-80", lhPrinter, 0)
If lReturn = 0 Then
MsgBox "The Printer Name you typed wasn't recognized."
Exit Function
End If
MyDocInfo.pDocName = "KassaPrinter"
MyDocInfo.pOutputFile = vbNullString
MyDocInfo.pDatatype = vbNullString
lDoc = StartDocPrinter(lhPrinter, 1, MyDocInfo)
Call StartPagePrinter(lhPrinter)
sWrittenData = ""
For n = 1 To 0
sWrittenData = vbFormFeed & vbFormFeed
Next n
sWrittenData = sWrittenData + Chr$(29) & Chr$(86) & Chr$(48)
'sWrittenData = sWrittenData + Chr$(29) & Chr$(86) & Chr$(1) & Chr$(0) & Chr$(10) & Chr$(10) & Chr$(0) & vbFormFeed
lReturn = WritePrinter(lhPrinter, ByVal sWrittenData, _
Len(sWrittenData), lpcWritten)
lReturn = EndPagePrinter(lhPrinter)
lReturn = EndDocPrinter(lhPrinter)
lReturn = ClosePrinter(lhPrinter)
End Function
