i used inpout32.dll in my program to give me control over the printer port, but it is to slow. I am using it to control a Infra red Circuit and speed is Crucial .
Is there a faster way to access this port.

Don't use the printer portGoogle for the specs for that port and see what the physical HW is capable of supporting throughput wise. Since that will probably be depressing, you might not even bother to look at ways of compressing the signal (which might not even be possible if you can't change the IR circuit) to get better throughput.
All in all I'd say your out of luck.
Heres one clip from googling...
decent link for info
The Enhanced Parallel Port (EPP)
The EPP was developed in 1992 by Intel, Xircom and Zenith and is sometimes referred to as the Fast Mode Parallel Port. EPP can operate at close to the ISA Bus speed, providing about ten times the data rate of the older Parallel Port modes. Transfer rates in the order of 500K to 2MBytes per second are possible. This is achieved by allowing the hardware contained in the port to provide flow control, (hand shaking) rather than have the service routines do it.
The IEEE incorporated the EPP standard into its document 1284-1994 but because some minor changes they made to the 1992 version of the standard, we now have two incompatible standards for EPP. There is the original EPP Standards Committee version 1.7, and the IEEE 1284 version. Because the differences were only minor, new peripherals can be designed to cope with the two variations, but older peripherals made to the original EPP 1.7 standard may not work with the newer IEEE 1284 ports.
i have it working perfectly in dos so i know the printer port can do the job. it is just inpout32.dll is a slow way to control the port.

You'll want to use GiveIO or UserPort to give your process access to the IN and OUT instructions - then you can do it in assembly
I talk about it here.

i though the topic read "faster porn access"
