Try to study this...

Public Declare Function Inp Lib "inpout32.dll" _
Alias "Inp32" (ByVal PortAddress As Integer) As Integer

Public Declare Sub Out Lib "inpout32.dll" _
Alias "Out32" (ByVal PortAddress As Integer, ByVal Value As Integer)

Public Declare Function Inp32 Lib "DllPort.dll" (ByVal PortAddress As Integer) As Integer

then,

Dim D as integer

'Send the integer to the parallel port using inpout.dll (The "&H378" tells it that it is a data port and the integer tell it wich pins to turn on)

Out Val("&H378"), Val(D)

I hope this give you a little idea...

Take note that PCI- or USB-printerport adapters do not use the same register sets as "proper" LPT ports. INPOUTnn.DLL will not give results because the hardware between CPU and port is totally different.
