Add a simple code for customized print from a webpage

We have a PHP based payment tracker application which works with MySql server and is locally hosted. The Applications works as a tracker for outstanding payments to be received from various clients of a firm. The application works perfectly and have the option of printing the names of the clients, outstanding & the Total outstanding amount. However, we want you to add a simple option where we can only print selected Client names and data, as our current system prints all the client names and their total outstanding. We already have added the options for selecting client names for deletion, you just need to code the printing of selected data/clients. You can refer to the screenshots attached (which shows you the current mode of printing). It's a basic & simple programming project. We want only serious bidders so please write "I UNDERSTOOD" in your proposal, else we won't be considering your bid. Thanks!
