    Opening printer port.

    Hi.

    I have a computer running a third party software (POS). The thing is
    this application opens the printer port and I need to use another
    program while the first one is still running.
    Since the other app has the printer port windows shows an error
    (path/file access error).

    Is there a way that two applications can share the printer port?

    Thanks for your help.

    William.

      The port can't be shared. However, you can add a printer port by installing a
      parallel port card. The new printer port would be LPT2.

          Two app's using the same device is much like two cooks using the same pan
          (trying to execute their own receipe): you would not want to eat the result
          :-)

          Maybe you should follow "the Wiz"-es suggestion : put another printer-port
          into the computer.

              They both need to use the same printer.
              I guess a work around would be to install a new printer port and
              connect LPT1 and LPT2 to a smart dataswitch and then to the printer.

              Doing this users can't blame the application :)

              thanks.

                  just a thought but have you tried installing the same printer again on the
                  same port, but with a different name?
                  I sometimes do this and set one to default black and white and the other to
                  colour ,so all i have to do is change the "printer" instead of settings. But
                  this could possibly help if it thinks its printing through a different
                  driver.

                  the other thing is.. have you tried the printer.enddoc method to close the
                  printer port before trying to open it in your app?

                  may or may not work.... but its just a thought
