USB to 25pin LPT1 adpater?


GoogleDude

Recommended Posts

I am new to this form so thank you for any help that you all can provide, a friend of mine said there are some really smart people here!

I have a Compaq Presario V3032 Laptop running XP SP2 and it does not have a female 25pin LPT Port like my desktop does and I need one.

So I went online and purchased a USB to 25pin female cable which gives me the physical port I need but the only problem is that Windows XP see's it under Device Manager as a "USB Printer Support" and not a LPT1 port.

It only came with Windows 9x drivers the readme on this cable said Windows will install/contain the drivers. which it did but only the wrong one. I have even tried a Targus Port Replicator but even it shows the same thing.

So my question is: How can I get Windows XP to see it as a LPT port and not USB Printer Support? I tried changing the driver under Device manager but it would always give Error 10.

Many many thanks for any help one can provide,

So far I have tried 2 of them 1 of them is some no name brand its just a simple cable with USB on 1 end and DB25 female. I would think that I can just tweak the driver that xp uses or do some reg hack?

The problem is I am not hooking a Printer up to it. And right now as it stands my device wont work.

Thanks for the sugestion,

Anyone know of a way I can tweak a Windows Driver or anything so I can make Windows XP see this cable as a LPT1 Port and not a USB Printer Support? I am not using this cable for a printer but rather a different purpose.

This is the one I have.

To have a "real" LPT port you have to purchase a true lpt controller, not a usb adapter/converter.

For example some printers using the old Windows Printing System (WPS) works only with true LPT ...

Good luck !

WOW. Converting a converter. :) I think that will get me into more trouble then this is worth. I was just hoping that I would be able to tweak a windows driver so I could use my USB 2 DB25 cable. But I guess that aint gona happen.

Thanks a ton thoguh.

I have a problem. I bought a Express card --> Lpt converter because my notebook (IBM R60) hasn't any LPT and I need it for controlling CNC machines or LPT led efect. (A USB --> LPT converter I can't use because it works together with a printer only.) But the problem is that the LPT port of the express card is diffined in system as USB Printing Support (It works pass the USB controller). I need set it as normal LPT port. Is any technique to set it? Or is any computer program for it?

The Express card is: STLabs ExpressCard 1port Parallel C-370

Thank you.

PS: Please excuse my bad English

From what I can see on the manufacturer site, the card creates an USB like simulation, just like a usb to parallel cable.

You might want to try using this workaround through the use of the MS loopback adapter:

Your mileage may vary. :ph34r:
