Don't want to print iteration number and residual norm in Cusp.

Hi I have written a library for CG (and other solvers like BiCG) using CuSP and using it in OpenSees(which is a opensource package for earthquake simulation) but when getting the results for each iteration CuSP prints iteration number and residual norm which makes the results more clumsy. Is there any other way to skip this printing and get only result for X?

Thanks
Waiting for positive reply.
