Is that the printer or the printing backend on the PC? I've noticed that, if I'm messing about with printer setup and accidentally start printing 200 pages of garbage, simply lprm-ing the job or clicking "Cancel Job" on the CUPS web admin page is not enough. I have to turn off the printer AND do a kill -9 on all the processes associated with printing that job. Which is a pain. > > You have to physically pull the plug to clear the memory. > > It's a feature. The ATX PCs are mostly on, even when ``off'' (think > standby), too. Which is a misfeature. Sometimes on a dual-boot system "ATX-off" isn't enough to reset everything and you have to pull the plug to avoid it locking up when booting the other OS. It can also result in damaged hardware if you swap bits around without pulling the plug. I make a habit of installing a "proper" power switch - double-pole mains contacts for the mains input, and auxiliary momentary low-voltage contacts to which the leads for the so-called "power" button are connected (this type of switch is commonly found in TVs and can be obtained from places that do TV spares). -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F
