    Printing directly to LPT/COM

    I have this in VB6

    Open "lpt1" For Output As #1
    Print #1, "abc"
    Close (1)

    How to do this in VB.NET? I am trying with FileOpen but it doesnt work. Can
    anyone help?

    Thanks

      Hi,

      There are a couple of ways.

      You can download IONet.dll from my homepage (a device driver wrapper that
      allows direct access to physical LPT ports, but not virtual ones, such as
      USB), or: http://support.microsoft.com/kb/322090/en-us

          You're best off asking this in a dotnet newsgroup.

              Duh! I now see you did crosspost to a dotnet newsgroup. For the record, the
              microsoft.publi c.vb.* newsgroups are for VB6 and earlier. In the future,
              please don't include them in crossposts for dotnet-related questions.
              Thanks!

                  Now I'm confused. Isn't this a dotnet newsgroup?

                      There is no "this", there's a "these" -- two incompatible groups.

                      The OP cross-posted to two NGs. Groups with "dotnet" in their names
                      are indeed for dotnet. Groups with just ".public.vb ." in their names
                      are not. Hence the confusion.

                      Just to clarify: microsoft.publi c.vb.winapi is NOT a dotnet group.
