Printing texts using TRichEdit is very easy, we just need to call Richedit. Print method and what ever the texts in TRichedit will be printed. First put a TRichedit control on a form and set some lines data.

It also provides lots of procedures to print the drawn data in canvas. Writing directly to the printer's canvas provides more control than using someone else's components. To use Printer object add Printers unit to your uses clause and use the Printer function to access the global object of TPrinter.

Following are some important functions of TPrinter object. So I have put a TMemo control and a button control. On button click I am printing texts in memo with using Delphi Printer object.

PrinterIndex, Printer. Printers and Printer. Orientation properties. ProcessMessages; It sends one raw character at a time to the parallel port. It waits for the recent character to get processed and then immediately sends a new one.

I got it printing stuff pretty fast. Good luck! Chris ] Glenn Jone Delphi Developer. Text ; System. CloseFile PrintMsg ; end; This prints to the default printer. You just use the printer as if it were a text file.
