Deskjet 6940 printer driver

[LL6940]

Searching for a driver or work-around to be able to print to the 250-sheet paper tray.  Prior to Win.7, if the top tray was empty the machine would automatically default and print to the 250-sheet tray.  Win.7 will not accept the original full version install desk or drivers NOR are the options in the printer properties/device settings accessible in order to select lower tray or upper then lower tray.

@LL6940,

Good day. Thank you for taking an interest in the HP support forums I will be happy to assist you. Great description of the issue. Kudos to you for that.

• Did you try the built-in windows drivers?
• Did you try a root level uninstall and reinstall of the printer drivers?

Let's try these steps:

• Perform a hard reset on the printer from this link: https://support.hp.com/in-en/product/hp-ink-tank-wireless-410-series/16180953/model/16180954/documen...  perform steps from the section “Step 1: Reset the printer
• Then update the printer’s firmware by following instructions from this link: https://support.hp.com/bg-en/document/c02919168
• Use a USB cable to update the printer’s firmware connecting it to a computer.

Then uninstall and reinstall the printer drivers at the root level by following these steps:

• Uninstall the printer from "programs and features" which can be accessed by doing a right-click on the Windows button (Please have the printer Off and disconnected during uninstallation.)
• Check in device manager, if the printer is listed there, please delete it. (Right click on the Windows button to access device manager)
• Go to devices and printers, in the control panel and select any printer listed there and you will get some options on the top. 
• Click on print server properties. 
• You will get a popup, click on the drivers tab and delete all the HP printer drivers listed there if any.
• Delete all the instances of your printer listed in devices and printers.
• Restart the PC.
• Once the PC is on the desktop, press Win + R, it would bring a Run dialog box, 
• Type %temp% in the run box and click Ok or hit the Enter button.
• It would bring up the temporary files folder. Delete the files in the folder (You might not be able to delete all the files).
• If possible, delete the printer from the registries using Regedit or using any other 3rd party application.
• Ignore the Regedit option if it cannot be done.
• Restart the PC again. 

Then download the latest full feature driver from  https://support.hp.com/ie-en/drivers/selfservice/hp-photosmart-c4600-all-in-one-printer-series/37391...  and install it on the computer after selecting the correct operating system.

Connect the printer to your computer only when the setup prompts for the printer.

This should fix the issue.

If this does not do the trick, please download the Windows Built-in drivers by following instructions from this link: http://support.hp.com/in-en/document/c01796879

Otherwise, try the Basic drivers. One of these should do the trick for you.

Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂
