Printing reports is a feature or function must consider when developing an application. Clients require this as an evidence-of-transaction. In this, they can find out the processes, statistics and integrity of data. Consider an E-POS System (Electronic Point-Of-Sale), after a customer paid all the bills the program will print a receipt. Printing is easy if develop as desktop application, but what if web-based application? Problem is when printing using the web browser it will always confirm (print dialog box popup).
