Operating System: Microsoft Windows 10 (64-bit)

DeskJet 3750 all in one printer driver appears not installed in Windows device manager.

I installed the HP Smart App and the printer is listed. I could print a few papers yesterday, but now I got the message "Align the printheads". I clicked on it and one paper was printed. I also printed Quality print diagnosis and it says printer is working properly and that the status is "Ready", except I can't print any document. 

 

Now, why is there a yellow exclamation sign in the device manager and the message that there is not driver installed for this printer? The only available download was at 123.hp.com, and that is the HP smart App. There was no CD in the printer's box and no other link.

 

One side note: I worked fine until I connected it to Wi-Fi and tried to print from my mobile. After I selected the printer listen in my mobile, the status of the printer in the app appeared to be loading (the blue circle). The document didn't print.
