Title: USB to DB25
Post by: comitop on October 29, 2010, 11:15:35 am

I wrote a program in BV.6 using the parallel. This program runs find on a desktop computer. I would like to upgrade to laptop. The laptop doesn't have a parallel port so I bought a USB to DB25 (bi-directional) parallel cable, install my program and coped the inpout32.dll to the system32 folder. Nothing happen.
 Do I need to upgrade my inpout32.dll or use something else?

I notice that it an USB Printer interface  connection
is there a way to read/write to this connection in VB.6

For direct port access, you could give this a try:

All of the other USB/parallel adapters I'm aware of work only with printers.
