The error reads " Windows found driver software for your device but encountered an error while attempting to install it,
"the specified port is unknown". Have tried an older print driver ( pl532en ) according to some posts I read and have disabled the driver signature but still no luck. Please help. Thanks.

Please try to downloading the hpgl2 driver and setup manually.
If possible use windows 7 64 bit.
I hope that download will help to you.

Thanks Rashed. I will try it but I am running Windows 10 . I had to reformat my hard drive last weeek due to a security issue and after re - installing Windows 10 , I could not get my plotter to work. the first time I installed Windows 10, I had no problem installing the driver. I don't know why it is different this time. Will let you know how it does.

Is it customize windows or as well pack.
I am also installed that printer in windows 10.
Are you using this printer with windows 10 in previous time.

Yes, I tried to install that driver Rashed but it did not take. And yes, my plotter used to work under windows 10 pro but after I reformatted the drive and re-installed Windows due to a security issue, it won't work . The re-install was not customized, just regular installation off the disk.

First off the gl2 driver will not work unless the printer has the gl2 card installed. I have seen issues with windows and usb connections since the plotter is usb2 and windows 10 support usb3. I usually suggest if the printer does not have a network card for the user to obtain one from ebay and the use a ethernet cable to connect the plotter to the switch or router and then connect the printer using tcp/ip. You will want to get a jetdirect 610N, 615N or 620n as they are all supported by your printer and have a resonable cost.

Thanks for the input. I don't have a switch or a router in the house, and I didn't need one before I reinstalled
windows 10. That is what i don't understand, it worked before so why is the USB issue an issue now? Is there any way to "customize" windows 10 with a usb 2.0 capability then?

The problem is not the usb 2.0 but the computer and windows 10 not liking usb 2.0. It could be your issue and then again it may not be, but from all I have seen on this forum it appears there are issues when usb 2.0 legacy printers are being used with windows 10. A lot of this seems to have occured with later version or upgrades of windows 10. See if you go into the computer settings and somehow change or adapt the usb ports to 2.0.
