[sudo-prints] brother printer, cancelling jobs

[Jake]

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
