I'm reopening this thread because today I had a problem with this plotter in windows 10 64 and I found the solution, both for the driver installation and for Autocad to detect the plotter correctly, because with other HP drivers installed the plotter could print certain types of files such as PDF or JPG, but could not print from AutoCad.
If you are still running a 32-bit operating system, then you are long overdue for an upgrade. Not only is NVIDIA dropping support for 32-bit systems but AMD has done the same a while ago and for good reasons. While NVIDIA has promised to offer security updates in the form of Windows 32-bit drivers up till January 2019, the 32-bit drivers that will be launched with in 2018 (GeForce Driver 390 Series) will not contain any performance updates or new features for such systems. Those will be kept for 64-bit operating systems only.
Although the new MacBook line no longer uses the X3100, Mac OS X 10.5 shipped with drivers supporting it that require no modifications to the kext file. Mac OS X 10.6 (Snow Leopard), which includes a new 64-bit kernel in addition to the 32-bit one, does not include 64-bit X3100 drivers.[citation needed] This means that although the MacBooks with the X3100 have 64-bit capable processors and EFI, Mac OS X must load the 32-bit kernel to support the 32-bit X3100 drivers.[citation needed] November 9's 10.6.2 update ships with 64-bit X3100 drivers.[citation needed]
Apple removed the 64-bit GMA X3100 drivers later, and thus affected Macs were forced back to the 32-bit kernel despite being 64-bit clean in terms of hardware and firmware. No 64-bit drivers were offered in OS X Lion. Subsequently, OS X Mountain Lion dropped 32-bit kernel booting. The combination of these two changes in graphics driver code resulted in many Mac revisions being unable to upgrade to Mountain Lion, as their GPUs cannot be replaced.
Intel has released production version drivers for 32-bit and 64-bit Windows Vista that enable the Aero graphics.Intel introduced DirectX 10 for the X3100 and X3500 GPUs in the Vista 15.9 drivers in 2008, though any release of DX10 drivers for the X3000 is uncertain. WDDM 1.1 is supported by X3100 but DXVA-HD is not.
I've also come across the nolowmem boot option, which is supposed to load "the operating system, device drivers, and all applications into addresses above the 4 GB boundary," but it seems to only be for 32-bit versions of Windows. I tried enabling on Vista x64, but the machine wouldn't boot up. I just set up this machine a couple of days ago, so it didn't have any service packs; I'm currently installing those to see if this is due to a Windows bug.
