I hooked up my HP printer directly to my computer using a usb cable that was working yesterday. Vista 64 bit OS won't recognize any printers (have tried 2 different printers) on any of my usb ports. I tried reloading the printer software, and uninstalling the usb drivers from device manager and reloading them, and nothing works. All use to work yesterday. I tried using a wireless print server, which works great from my laptop, but when I tried the desktop PC it wouldn't load the connectmgr.exe file and it's .dll files it needed. A helpful buddy said to remove the printer drivers and then reinstalling them. I did just that and no more printing from this PC. I managed to get the print server software to work. I just copied the necessary files from my laptop to my desktop and the print server works OK now. but doesn't recognize any printers. Everything still works good from my laptop. I finally got the printer software to load after many tries, but windows Vista still doesn't recognize any printers from any usb connections on my desktop PC. Any help would be greatly appreciated. Thank you.
