Printing separate back-to-backs getting stuck in queue

For the kast several months I've been having a problem when I attempt to print separate dense back-to-back PDF files. The first one prints with no problems. however, the next one gets stuck in the queue. It may print a few mins later, but, usually I have to clear the queue. I'm using W11 and a HP 8025 printer attached by a USB printer cable. W11, the HP printer, and Adobe Reader are all current with updates etc. I've run every diagnostic availabe and they all tell me I have no issues. I contacted MS support and they said to try a different PDF printing app. I tried the Firefox embedded PDF app and there was no difference, hwoever, when I tried the Chrome embedded PDF printer app I had no issues. I printed separate files with not hang ups. I would mention that if I download a multipage file, all at once, I have no issues. All pages print without interruption. At this point I can only conclude there is some issue with the Adobe Reader software, I look forward to anyone's comments. Thanks
