first off, none of that stuff is available to the user unless he has 
hacked his $PATH statement.

Using the arrowed return line above, what then does the lpadmin cmd line 
look like?

What is QUEUENAME? Arbitrary/anything?

Thanks Gareth, but I just posted an attcachment of the ppd it generated, 
looks busted to me.
Let me repeat for probably the 20th time, that brothers drivers have 
been working flawlessly
with this printer for several years and many installs since wheezy was a 
puppy.

You'll see that ppd specs the bottom tray, but it actually uses the top 
tray, that I normally keep
$mucho dollars photo paper in. Removed in self defense of my bank 
balance until this behaves.

Thanks Gareth

Cheers, Gene Heskett.
