My Dell 1250c color laser printer won't print from my new HP laptop on Windows 11.

I have recently changed laptops from a Dell Inspiron to a new HP17 laptop PC17-c2000.  I have two printers, a Brother mono laser and a Dell colour laser.  When I connected the Brother printer, the new laptop recognised it straight away and I've been able to print from it with no problem. 

I connected the Dell colour printer to it and the laptop didn't  recognise it at all.  I've downloaded and installed the drivers from Dell and manually added the printer.  The laptop says that the printer is correctly installed.  However when I try to print, the job apears in the print queue and then it will say that it has printed but nothing has printed. I hear the printer starting up but the drum doesn't turn and no paper feeds through the printer. 

I reconnected the Dell printer to my old Dell machine to test it and it printed fine, so I know the problem is not with the printer but with the instruction it's receiving from the new laptop.  For some reason it just refuses to print.

If it's of any relevance my new HP is running Windows 11, but according to Dell's website the printer is compatible with Windows 11 so this shouldn't be a problem.  I've tried all the usual restarting the laptop, switching the printer on and off etc to no avail.

Grateful for any help as I've been trying since last week but with no success.
