[sudo-prints] brother printer, cancelling jobs

so i tried to edit the wiki page for the brother printer, here: https://sudoroom.org/wiki/Brother_HL-2270DW i wanted to put in a prominent thing called "HELP! how do i stop it printing stuff nobody wants?" and i sortof did, but i didn't know what the proper instructions were. the other day, it was spitting out a million copies of something that someone tried to print earlier, while the network was down. we tried turning off the printer and waiting, but it would just start right back up when we turned it back on - printing on both sides of nice blank white paper. I went to the printer's control page at http://192.168.1.8 but it wouldn't allow me to do anything with the user login, and the admin login was unknown so i couldn't try that. then i emptied the print spool on the computer that the jobs had come from, with lprm - to cancel all jobs (and there were several) but it didn't seem to have any effect. this is the nightmare that comes with WIRELESS networked printers. that is, if you think printing on both sides of papers until the printer decides it's done (how many times did the person try to print before giving up?) is a nightmare. i wish printers had an "expire jobs" setting so that they wouldn't try to print stale jobs from hours ago. so... can someone put instructions on the wiki on cancelling print jobs? thank you -jake
