Printers shows a "Unable to Connect"

If your printer list in Windows shows all your printers as "Unable to connect" then this means you have more that 35 printers in your list, if you reduce this number to under 33 (<33) they will all connect again...

This affects Windows XP and Windows 2000, my advice is to run Clean Spooler weekly.....or you could Disable the Printer Spooler service to make your PC paper friendly....
