My PC has two printers shared by a junction box. Recently the HP laser printer has been spewing out paper with rubbish on it. It's obviously trying to print with the HP720 driver. The cause appears to be "local downlevel documents" which are 49K long, appear mysteriously in the HP 720 printer queue, but print onto the laser printer immediately it is switched on. I don't know what generates these documents or how they can be blocked. Any help greatly appreciated. I'm on Windows XP Home
