I've recently helped many people  who found Windows 10 on their computers unexpectedly. So, no, you aren't imagining things and no you didn't accidentally click on the wrong thing...Here's what I've found:

"The Windows 10 upgrade is automatically being installed on many Windows 7 and 8.1 machines as a result of Microsoft changing the status of the upgrade to that of a "recommended" update. Windows 7 and 8.1 machines sold to home users are generally configured to automatically install these recommended updates."

Every day I read online articles that tell me the older HP Designjet Plotters can not be used with the newer Windows 8 and Windows 10 (aka: Win8 or Win10).  I say BS! I just today help another guy, Sam from Pennsylvania to connect his Designjet 750c to Windows 10. Sam asked me to log on to his screen and just get it connected.  We downloaded the drivers from this site which I copied directly from HP some time back before they took them off their website. Then I showed Sam some of the tricks of the trade...how to resuscitate old cartridges, how to use the USB connection and how to change ports when necessary.  When we were done Sam was printing with his old 750c Designjet! So call me today for help in connecting your older plotter to your newer Windows 8 or 10 operating system. I'll charge you $50 only if we are able to connect your computer to your plotter and get you printing!         651-247-3022 ask for The Princess!

How can I install non-digitally signed drivers in Windows 10? (see below for Win 8)
Windows 10 enforces driver signatures by default. What this means is you can download a driver from this site or others, but the driver signing requirement kicks in and "disables" the driver...you won't know it...it looks like it is there and functional. This is because drivers weren't signed back in the 90's! You might get a message that says something about a hash tag...but your downloaded driver won't work. YOU MUST DELETE THE DRIVER FROM YOUR SYSTEM AND REMOVE THE PRINTER FROM YOUR LIST OF PRINTERS. This can be disabled to install drivers that are not digitally signed. Use the following steps to disable driver signature enforcement.
NOTE: If this is all too intimidating or too much  of a hassle you can call the Plotter Princess and for $50 I will remotely connect to your computer, download the drivers, install the printer/plotter and get your plotter to print a test print...so you can be sure you are properly connected and ready to get some work done!! Usually an appointment is not needed. Call 651-247-3022

How can I install non-digitally signed drivers in Windows 8?
Windows 8 enforces driver signatures by default. This can be disabled so non-digitally signed drivers can be installed. Use the following steps to disable driver signature enforcement.

1. Press the Windows () key + C, or swipe in from the right edge of the screen to open your Charms.
2. Select the Settings charm, and then click Change PC settings
3. Select General, and then scroll down and click on Restart Now under Advanced Startup.
4. Click on Troubleshoot, Advanced options, and then select Startup Settings.
5. Click on Restart.
6. On the Startup Settings screen press 7 or F7 to Disable driver signature enforcement.

Once the computer restarts you will be able to install non-digitally signed drivers for that Windows session. If you restart the computer again the driver signature enforcement will be enabled. You can repeat the above steps at any time you need to disable this feature.


​When next you restart your computer after this the driver signing requirement will be back in force. That's a good thing because it saves you from viruses. Any driver on this site was copied from the original HP driver sites before those lovely folks at HP decided to get rid of them so people like you couldn't use those old plotters anymore!

My most asked question these days is how to use the older plotters with Windows 8 and 10. You CAN do it. I've helped lots of folks to do it. Just last week we put an old Designjet 650 on a Windows 10 computer!
Here's an article on how to do it.

I'm getting lots of calls and emails from those who have uploaded the new Windows 10. Can you use your plotter with Windows 10? GOOD NEWS - HP has published Windows 10 drivers for many of the newer plotters. Alas, we don't see them publishing for the older (700's, 600's, 200's) plotters. 

First go to the Designjet page on the HP.com website and choose the series for your plotter. On the next page choose your specific model and go to the driver page. If your plotter is supported in Windows 10 you'll see a driver listed in the operating system drop down menu. If you don't see one, it appears that it isn't going to work in Windows 10. 
But--wait! Go here to find out how to make this work!
