Pages app not recognizing HP printer for printing on iPad Pro

Printing issues

I am using an iPad Pro, with an operating system iOS 18.6.2

I am also using an HP printer. Model HP Envy 6055e. And the panel light that indicates the printer is online is blue, indicating that it is online.

Up until about a week or 5-6 days ago, I was able to print directly from the Pages app. And suddenly, I couldn’t print on my HP printer. It shows the printer as being offline.

But, if I am using a pdf program, I can select a file and print it without any problem. So the printer is online for pdf printing.

And if I use the HP Program, I can print pdf files, but it gives me a selection of files to print, but only pdf files.

What’s happened? 

How do I get Pages to recognize the Printer?

I’ve unplugged the printer for a few minutes, and then replugged it , but got no change. 

What’s happening?
