Check errors while printing

Question

Hi dudes, i've a question, i hope u can help me. My application needs to print tickets just once, i've a table in the DB with a bool field [impr_status] is FALSE by default, the thing is when i send the print from de Report Viewer how my app will know if the print was correctly (in this case set de field to TRUE), in case of any error how can i catch it and then manage it.. thanks in advance. Ivan.
