errors during diagnostic check

[Ale83]

Hello, 

my printer is not printing properly through my laptop but it's working properly through my mobile phone.

I did a diagnostic check and I got the following messages:

1) cannot resolve port conflict

2) impossible to complete the check of the queued object

3) impossible to complete test print

4) impossible to complete offline print

In the HP smart app the printer looks connected properly and I can see all the other details (status, connection info, IP, etc...)

But printing doesn't start.

I've also tried to re-install the whole SW package, but doesn't help.

Also associating the printer again, doesn't improve...

Can you please help me?

Welcome to HP Community

I have gone through your Post and would like to help

Try uninstalling the printer from root level and download the full feature software

1.) In Windows, search for and open Programs and features 
2.) Select your HP Printer 
3.) Select Uninstall 
4.) In Windows, search for and open Devices and printers 
5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose ‘Delete’ or ‘Remove Device’ 
6.) Open up the run command with the “Windows key + R” key combo.
7.) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”) 
8.) Click on the “Drivers” tab 
9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom 
10.) Select Ok 
11.) Select Apply and Ok on the Print Server Properties windows 
12.) Close Devices and Printers
13.) Restart the computer and download the Full Feature Software from Here and follow the onscreen Instructions
