1.	Solve : Lexmark printer "Ready" but won't print?
Answer» Installed new Lexmark X5470 PRINTER which says "ready" but won't print. No communication between printer and COMPUTER. Manual test page prints OK. Tried with firewall turned off but that didn't help. Latest drivers installed. Using Windows XP Pro on a HP Pavilion A257c, 512MB, 120GB Ultra HD, Symantec anti-virus, windows firewall. Any advice appreciated.Turn the printer off. Disconnect the power. Disconnect the USB cable. REVERSE the order to RECONNECT. If this doesn't work, reboot the computer.
