All jobs cancelled and still printing junk

[WL Yeow]

Hello,

I have the exact same problem and I would like to know 2 things:

1) if there's any elegant way of killing print jobs. As a sysadmin, I would want to limit shell access to users who really needs them, not those who just need to cancel print jobs.

2) when the printer jams or encounter errors in printing, why isn't it reflected in CUPS but continuing spewing junk? Is this a printer driver problem? my printer is a HP810C, if that info helps.

Thanks in advance for any assistance.

Regards
WL
