I do not understand what exactly you mean. Ususally it cannot work when one process (your ink level program) communicates with the printer to query its ink levels while another process (the CUPS backend) sends print-data at the same time. You need to implement mutual exclusion. By the way: Do you know about /usr/bin/escputil (see "man escputil")? Perhaps it works for your specific model.
