EdiMax PS-1206MF Ethernet-to-USB printer connector

[Peter Flynn]

After some struggle with Ubuntu's UI for CUPS (or maybe it's CUPS's UI 
for Ubuntu) I gave up trying to get this gizzmo to work when I found 
that I *could* make it work using the CUPS web interface.

I'm not clear why one route should work and the other not: using the UI 
route, I could set up the printer but nothing ever got printed. It 
created the job, but it just sat there forever.

However, using the web interface each job gets printed OK, but never 
gets cleared or deleted afterwards, and there seems to be no option to 
force this. I have to manually click Cancel Job after each job is 
printed, otherwise the next one in the queue never prints because CUPS 
believes the first job hasn't finished yet.

My guess is that this is some bug in the EdiMax box, failing to pass 
back a completion message. Is there some way to force CUPS to time a job 
out and delete it even though CUPS may believe it to be current?

The other puzzle is printing large sheets (this is a HP 1220C capable of 
A3 or 13"x19" paper). CUPS can be set to do this, of course, and the 
test page is fine, and even Acrobat Reader appears to believe the 
settings, but when it goes to print, the page either comes out A4 or 
refuses to rotate to print landscape pages correctly. Something 
somewhere isn't synchronising properly...but what?
