No, because printing is not something covered by the C standard, or that for most programming languages. Use a toolkit, like QT or GTK. If you know the native format for the printer (e.g., Postscript/PCL or whatever), and how it is hooked up to the machine, you can open the printer device in your program, generate a file in the appropriate format using a library like netpbm, and send it to the printer device. > Q.

Of course any existing applications would need to be reworked for a new framework, unless the new framework had some backward compatibility mode. Regards, Gora
