Are you saying if my class is Dop I should have
class Dop(object):
def _latex(self,GaLatexPrinter):
etc.
where GaLatexPrinter is my custom latex printer that has member _print_Dop.

You can define methods on the class, depending on what printer you
want to override. For the LaTeX printer, it's _latex. The signature
should be _latex(self, printer), and it should use printer to
recursively print any subexpressions. See
http://docs.sympy.org/latest/modules/printing.html#module-sympy.printing.latex
(the printmethod attribute), and search the SymPy codebase for some
examples.

Can you suggest how I could override the function without
modifying interactive/printing.py?

Maybe you need to override this function:
https://github.com/sympy/sympy/blob/master/sympy/interactive/printing.py#L90
Notice how some odd classes that don't fit the sympy standards
have special cases. Try adding your class to that list and see if
it works.

I am trying to print a list of instances of a custom class.
The input is -
print (o3d.grad, o3d.grad)
the output is (custom latex printer)
$$ (e_{x} \frac{\partial}{\partial x} + e_{y}
\frac{\partial}{\partial y} + e_{z} \frac{\partial}{\partial
z}, e_{x} \frac{\partial}{\partial x} + e_{y}
\frac{\partial}{\partial y} + e_{z} \frac{\partial}{\partial
z}) $$
however in ipyrhon notebook I input
(o3d.grad, o3d.grad)
I get out
(e_{x} \frac{\partial}{\partial x} + e_{y} \frac{\partial}{\partial y}
+ e_{z} \frac{\partial}{\partial z},
e_{x} \frac{\partial}{\partial x} + e_{y} \frac{\partial}{\partial y}
+ e_{z} \frac{\partial}{\partial z})
Also the standard latex tuple and list printer is not using
\left ( \right and \left [ \right ) to enclose
the tuple or list. How can I write a custom latex tuple and
list printer that will also work in ipython notebook.
