Send Raw Data to ZPL Printer using Visual Basic (MS Access 2000)

Question

This is all that I can find, none of them work.

Method 2

Private Sub crtLabel()


Dim prtDevice As String
Dim strQuote As String

strQuote = Chr(34)
prtDevice = "ZDesigner LP 2844" ' whatever device Access currently has as the default. I have the user select a printer prior to printing, which sets the Access defaut printer

' open printer port
Open prtDevice For Output As #1
' initialize printer
Print #1, "OD" & vbCrLf
Print #1, "N" & vbCrLf
Print #1, "O" & vbCrLf
Print #1, "Q545,B12+23" & vbCrLf
Print #1, "q262" & vbCrLf
Print #1, "UN" & vbCrLf
Print #1, "rN" & vbCrLf
Print #1, "N" & vbCrLf
Print #1, "A4,94,3,3,1,1,N," & strQuote & "1803" & strQuote & vbCrLf
Print #1, "A36,74,3,3,1,1,N," & strQuote & "B" & strQuote & vbCrLf
Print #1, "A64,94,3,3,1,1,N," & strQuote & "079" & strQuote & vbCrLf
Print #1, "A112,8,0,2,1,1,N," & strQuote & strQuote & vbCrLf ' you can replace any string like "1803" with a string variable like SID or AID that gets passed to the sub
Print #1, "A112,32,0,3,1,1,N," & strQuote & strQuote & vbCrLf  ' same here
Print #1, "A112,64,0,1,1,1,N," & strQuote & "04/13/2009" & strQuote & vbCrLf
Print #1, "A130,100,0,1,1,1,N," & strQuote & "SWAB, NASO" & strQuote & vbCrLf
Print #1, "A4,100,0,1,1,1,N," & strQuote & "C146536" & strQuote & vbCrLf
Print #1, "B53,130,0,1,1,0,47,N," & strQuote & "2009-06868" & strQuote & vbCrLf
Print #1, "A112,188,0,1,1,1,N," & strQuote & "" & strQuote & vbCrLf
Print #1, "P1,1" & vbCrLf
Print #1, "O" & vbCrLf
' close printer port
Close #1


End Sub

Nothing happens after running the function. It's like the printer is not touched at all by the code.

UPDATE Method 1 is the closest thing I can get to printing the file. After executing the command, there is a printer icon at the status bar show that the printer has been called and receiving data from my code, but still, no printing at all. Help...

Answer 1

if it is mapped to a parallel or com port, you can open that directly:

open "LPT1:" For Output as #1
' or open "COM1:"
print #1, "SomeData"
Close #1
