Printing directly to printer

Hey guys,

I am working on a small app that chooses a file and when I click the print button it will simply print the file to the chosen printer(from the printDialog()).

I have looked at numerous tutorials and examples but most of them refer to printing components from swing or loading the file into a textarea before printing the text from that textarea.

I would like to know if there is a simple way of implementing the feature I am after and possibly some helpful code if kind enough.

I have also tried the Desktop class but opens the associated app to use its print feature.

Thank you

DP

Welcome to JavaRanch.

Unfortunately, there is no way to "simply print a file". Java knows what to do with certain file types (e.g. text and PostScript), but in general only an application that knows what to do with a given file format can print a file (say, a web browser for an HTML file, or Adobe Reader for a PDF file). That's why the Desktop class uses the application that "owns" the file to print it.

A smart printer can help (e.g., some printers know what to do with PDFs), but generally they need something like PostScript or PCL as input, not just any file format.
 
It is sorta covered in the JavaRanch Style Guide.
