If you're using Windows and you've installed a HP driver, VueScan's built-in drivers won't conflict with this. If you haven't installed a Windows driver for this scanner, VueScan will automatically install a driver.

AirPrint is a technology built into most popular printer models, including those listed here. With AirPrint technology, it's easy to print full-quality photos and documents from your Apple device. AirPrint features include easy discovery, automatic media selection, and enterprise-class finishing options.

The printers, print servers, and USB-only devices listed here are provided by each manufacturer and updated regularly by Apple. If you don't see your model, check with the manufacturer for more information.

To use AirPrint, you don't need to install an app, additional drivers, or other software. Just connect the AirPrint printer to your Wi-Fi network, then choose it in the print dialog when you print from your Mac or print from your iPhone or iPad, for example.

Similar to AirPrint printers, these USB devices allow you to print or scan without having to install additional drivers. Because they require a USB connection, they support driverless printing or scanning only from Mac computers.

I have uninstalled the printer via Devices and Printers on the Inspiron 17, shut down the computer, started up again, and installed the full software via OJ4650_Full_WebPack_1122.exe, as downloaded from the HP site. The installation appeared to succeed. I went through all these steps twice.

I have also run an apparently successful installation via HPEasyStart_5_5_3253_26.exe, and another via the HP Print and Scan Doctor. The HP Print and Scan Doctor continues to say the printer is not installed, even immediately after it has downloaded and apparently installed the software.

I've managed to fix this issue after it plaguing me for a week!
I dont know exactly which part of this worked, but I will just let you know every step that I took.
First of all, I followed previously mentioned steps of removing as much of the printer drivers as possible using the HP support guy's technique. To be honest I think the only parts I successfully deleted were the fragments in the &temp% folder as the rest of it was access denied or 'currently in use, try again later'.
Then in devices and Printers, 'remove device' completely, and also see if you can remove the driver from the printer server properties.
Once as much has been removed as possible, switch off your wifi, and dig out your dusty usb cable.
Once connected, the printer reinstalled itself and was working 100% as it should. Then I set my home network to 'metered' before switching it back on, as I found that this stops the driver automatically updating on my PC. I dont know for sure that it was the most recent driver that had the issue (all other reinstallation attempts had involved downloading the driver as opposed to getting it from the printer) but so far, so good.

If this didnt work, my next step was going to be to find the old disk that came with the printer and reinstall a previous driver that way. I only assume that an older driver might work better because this laptop is only 2 weeks old and the first week it was printing fine - just before an update. It might even be possible to get old drivers direct from HP website, i hadnt checked.

I signed up purely to answer this question as this has been a royal pain in my behind.
Hopefully it helped.

Thanks for the prompt response. I would appreciate it if you would read my original post with care. I worked on this problem for two days before posting. I have tried to supply all relevant information there.

I must admit that your response has the flavor of boilerplate selected by a mindless bot based on a few keywords which fail to describe my issue. For instance, you say, "I understand that you are unable to print in color from your HP OfficeJet 4650 All-in-One Printer." That is not an accurate understanding.

To reiterate a few points which make your response irrelevant to my actual situation:

= There are no color (or greyscale) options visible anywhere for this printer as seen on my computer - not during setup, nor in the properties, nor anywhere else that I can find.

= The Print Quality Diagnostic Page prints in color from my computer, via both the Toolbox in the HP Printer Assistant and the HP Print and Scan Doctor.

= Another computer prints to this printer in color without any difficulty.

I look forward to any advice folks can give me based on the specific circumstances I've described!

Thank you for your reply, I'll be more than glad to help you.

I understand that the print quality diagnostic page prints in color and also the unit prints in color when the print command is sent from a different computer.

I attach screenshots of the Properties available for the printer in case they help you see what the problem is. (You can see that the Printing Shortcut tab shows images with color; but the printout is still only in greyscale.)

As you have already tried these steps and still having the issue, I would personally suggest you contact our HP phone support for further assistance. If your product is Out of warranty then remember to choose the paid options to get the tech support number.
