How to solve my printing issue?

I just bought a new computer (Gateway), and it runs on the new Windows 11 software. The computer works great but it just won’t connect to my printer. I have an HP desk jet 2600 series and it won’t connect to it at all. I have reinstalled drivers and the HP smart app, and it worked for a while. Afterwards it’s not reading the printer again. It keeps telling me the printer is offline. Please can someone tell me what to do. I am open to buying a new printer, but I just want to make sure that I can print because I have documents that I need to print for my upcoming examination.
