1. How can I fire the code after click the print button in crystal report? Is there any events(lick click) to check the printer staus?

2. What are the properties change when printer in different modes like lid open, no paper, lidopen and no paper, swtch off, switch on, warmup ect.? what are the numeric values it exactly returns? and is there any changes in return values for different catagery printers(hp laser printes, canon ect..)?

3. How can I display the message "Success" after successful printing of a report?
