[cups.general] Creating printer

[ALi]

Hello,
I am member of group lp so i can create printers with command lpadmin
-p printer -v location -m model -E

but .... can i create a printer from model and model being from local
(for example /tmp/model.ppd.gz)? must i need perms over some
directory? i cant write on drivers directory, but i am able of
creating printer.

this is understanded? is this correct? i need perm of write model to drivers?
