Re: HP DesignJet 750C+ and Windows 10 64bit

HP Recommended

Hi guys,


i really need some help


so i was just gifted a HP Design jet 750+ plotter and i cannot connect it to my windows 10. ive tried every forum , i tried downloading the  pl532en driver and that did not work i even tried this. 


((((For those who has ran into trouble installing the pl532en on the newer version of window, you have to disable the "Driver Signature" recognition from Window 8 or 10 because the new window doesn't recognize the older driver pl532en (not updated to window 8 or 10 "stanadard").


To disable Driver Signature setting:

  1. Select the Restart option under power while holding down SHIFT Key (Window 8 or 10)
  2. Select “Troubleshoot” option
  3. Select “Advance options”
  4. Select “Startup Settings”
  5. Click restart so you can modify the boot time configuration settings when the computer restart
  6. When the computer restart, you can choose the “Disabled driver signature enforcement” (F7)


Once that is done, you can install the driver pl532. With that said, you may run into the same problem as when I was install the driver on Window 7.


To make sure the driver is working properly:

1.  I suggest plugging in the plotter

2. Go to "device manager" and you will see the printer pop up under "other devices" because window doesn't recognize the plotter

3. Right click the "plotter" and choose as printer under list of choices

4. Choose have disk and install the driver pl532en. This will make sure the driver work as a printer on window 7, 8 or 10.)))))


i tried this multiple times and will not instal the drive. 


I then found out on the step when i would normally choose the "have a disk"  to put in the pl532 option as a drive that i had the HP option on the printers page i looked thru it and suprisingly enough i found that i had HP Designjet 750cplus E/A0 as an option within my pc!!!! i was so happy!!!!!......then i followed and it still wont instal. 


PLEASE HELP ME i really need to use my plotter. 


i dont know what else to do. 2017-07-26.png

Hi, probably too little and too late but anyway and this was in relation to an HP Designjet 430 but may still be applicable to a 750C:


Supposedly if you want to print in color you can download this driver file (with some introductory verbage):


As you probably know many are using this driver for the 450C, 650C, 750C, etc. to work with Win 8, 8.1, and 10. But I think you have to disable windows driver signature enforcement although I think I used it once and did not have to do that.:



Also, you can, I think, find the same driver at--and I think this site gives steps on installing the driver in Win 10--just look around within this site and you will eventually find it:



Furthermore and a bit redundant, there is this post within this forum:
