4175 not printing

[Scoialom]

Refers to printer deskjet 4175 wifi issue

Device was working fine up to the stage I have changed web supplier and of course the router

I have updated the wifi definition and the device found the network and successfully connected

after trying' I found my computer did not succeed to detect  the printer and obviously did not print

I removed the device and reinstalled with the same results

I run HP Doctor. Now the printer is found but still not printing, it looks like a port definition issue:

On the other hand, even though I am connected to the web and surf normally, I get conflicted info about the connection status:

Hi @Scoialom,

Welcome to the HP Support Community

I'd like to help!

To assist better -

Are you able to connect the printer to other device?

What is the make of the pc?

Let me know!

The printer communicates with home net work and direct by usb with another computer.

It s now detected on my wifi laptop (asus) but is showing on Hpsmart as off line 

Before changing the router it was functioning

Try the below suggestions-

1)Uninstall HP Smart 

2)Install all the available Windows updates

If it is been a while since you updated your Windows, that is the main reason why Windows says your HP printer driver is unavailable. Here are the steps how to do a Windows Update to install all accessible operating system update.

If you are accessing Windows 10, then these steps are for you.

1. Hit the Start menu and write an update. After that, click on the “Check for updates” option.
2. Tap on the “Check for updates” option.
3. After clicking on that option, Windows will install the updates automatically.
4. When Windows completes all its updates, start your computer again and attempt to print a file to check if your printer works.

3) try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

4)Reinstall HP Smart App

If the error persists, install the HP Easy Start. 

Hope this helps! Keep me posted.
