Hi @GüWi,
Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for the First Time Here? Learn How to Post and More
I see from the post that you are having issues installing your HP LaserJet CM1017 printer. Don't worry as I have a few steps to help you get through this concern,
To provide you with an accurate solution, I'll need a few more details:
Have you made any changes on the printer before the issue started?
When was the last time it worked (date)?
In the meantime, let's start off by performing a Hard reset on the notebook and make sure that the printer is connected directly to the wall outlet and not to the surge protector.
With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
Remove USB cable, if present.
Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.
Turn on the printer and wait till warm-up period finishes and the printer is idle.
Let’s try to fix this issue by doing a clean install. Follow the steps mentioned below:
· First, unplug the USB cable from the printer if present.
· Go to Control panel – Programs and feature – Select all the HP DeskJet printer entries and uninstall them.
· Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
· Restart your computer.
· Click the bottom-left Start button on d the sktop, type device manager in the search box and tap Device Manager on the menu.
· Once in device manager, click on the view tab in the top & choose “Show hidden devices”.
· Then from the device manager list, check the entries under “Printer” – If there are any entries, please right click and choose “uninstall” – In the confirm device un-install pop-up, make sure you select the box which says “Delete the driver software for this device".
· Also, check the entries under "printer queue" and "imaging devices" and repeat the same exercise. Delete any printer entry or any entry which says “Unknown device”.
· Once done, close device-manger. Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.
· Under print server properties, go to drivers - remove any entry there as well.
· Again, go to run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
· Once done you can try cleaning out your temporary files and cached files. You can try using automated applications like some cleaner software's that you can download from the internet.
· Now restart your computer again.
· Open the Run window again, type “services.msc” and press ok to get services window.
· Scroll down to “Remote Procedure Call (RPC)” – right-click and go to properties. Make sure the service is started and startup type is “Automatic”.
· Now scroll up and go to “Function Discovery Provider Host” – right-click and select properties – Change the startup type to “manual” and start the service.
· Repeat the same exercise on “Function Discovery Resource Publication” as well.
· Since there are no drivers available for your printer, I would suggest you install Windows inbuilt drivers, using this link.
· Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.
Let me know if those steps worked for you.
If they did, that’s awesome!
Give us some reinforcement by clicking the solution and kudos buttons,

Good Luck.

The essence of that posting is a need to uninstall, reboot, and reinstall the HP Imaging software.
