USB to LPT/Parallel in windows XP

by ramyayad / June 4, 2008 3:32 AM PDT

Wondering if anybody have a solution to this one:
I have a usb docking station that has parallel port as one of the ports and I also tried USB to parallel cable.
USB to parallel port Usually windows XP add a USB printing service and doesn't show virtual LPT port at all and the software that i am using doesn't like that it needs to see LPT port "Not a printer by the way"
and now most of the laptops including mine doesn't have a parallel port.

By the way I installed Windows 98 SE on the laptop trying to figure out where is the problem and Windows 98 worked perfectly and showed the LPT port after I showed it the Driver.
Windows XP will not take the driver and it has to use it's own.

The make and model of the USB to LPT device might reveal more details.

Also why "not a printer"? If it's some dongle you can use a PCI parallel port (I use the Lava.)

I am an electrical Engineer I use a chip programer to program memory chips and microcontrollers and FPGA chips.

And both software that I have look at the parallel port LPT.

The link that you gave me is really great and looks like I am going to through everything away the docking station and the USB to parallel cable away and get the PCMCIA.

But i feel like I failed lol something so stupid like that and nothing we can do.
the make and the model doesn't really matter I used multiple mine and my friends and all does the same thing it uses the default windows XP driver which comes in as USB printing service not an LPT port.

I know that one!

We used to program Atmel CPUs via a parallel port. The timing was getting wonky (uncontrollable) as new machines came out so we reverted back to a DOS setup which means no newer laptops. Later we obtained a device programmer (which is on USB) which meant big savings as we no longer needed the staffer that maintained the old in house programmer.

I know this area well but I know it's "the end" for such things. You need to go with what works for you. Here we have a few old desktops for this and the newer programmers.

Installing USB to Paralell adapter driver in Win98SE
by master_pop81 / January 29, 2009 11:02 PM PST

I have tried to install USB to Paralell (LPT) controller driver in Windows 98SE as ECP Priner Port with driver from Windows 98SE installation disk (not the one from the CD that came with it), and all went OK, but the specific machine that works only through LPT port doesn't work. Machine is working perfectly through motherboards integrated paralell port.

Can anyone help me with this issue?

For the same reasons above. The details are not in the discussion. As this is a discussion forum and not tech support you must make a good post to get the details in your post.

It's been a few years and after tackling this very issue my bruises tell me I only use those USB to parallel cables on current operating systems.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
