I’m making a simple one-form Invoice bill printing, below is the screenshot to illustrate it.

I want to generate a report from the existing form after entering the data, simply static without database. Only the combo-box values are fetched from the database.
How can I generate that report after clicking the print button. The resultant report should not have combo-box, it should simply have a label instead of it.
I would always prefer to generate html files as reports. Its very flexible and printer friendly.
Create a html template with place holders and just replace with your required data.
