Enable bidirectional printing
I have a new studio xps 435MT. The problem is that I hp 4200 laserjet, but more importantly, I have a security key that needs to communicate with an parallel port in order for it to validate the software via a port key for use. I installed a PCI-E card which works, but the "enable bidirectional support" is grayed out in printer properties. From what I've read, it epp needs to be enabled in the bios, but I can't seem to find anything. I tried using the latest 64bit driver from hp. Any suggestions other than to return the system?

Are you using an IEEE-1284 cable?

I am having the same problem with a completely different setup. I have an Inspiron 530 with the AIO 810 on Vista Ultimate SP2 which has worked well for a year and a half. Recently it stopper working giving the instruction to enable bidirectional communication. This is grayed out in the properties and despite activating full administrator privileges refuses to change. I have deleted and reinstalled the printer without any luck. This problem started with Vista SP1 and continues with SP2
