    I don't believe VB provides any native support for accessing the parallel ports other than accessing them as files, ie Open LPT1: For Output As #1 etc. You can then write data directly to the LPT port using the normal file I/O statements eg, Print #1, ...blah blah

    On the other hand, the MSComm control that comes with VB gives you good access to the serial ports. If you're reasonably familiar with RS232 concepts, you shouldn't have too much trouble using this.
