The PC.ParallelPut procedure is not meant for sending a stream of characters to the parallel port (for example, if you want to send the string "Hello" to the printer). If you want to do this, open the file "LPT1" using the open statement and put to the file.
If not, please post some code so we have somewhere to start.
