Printfil allows printing from DOS, Unix, Linux, host programs to any Windows printer, including USB, GDI, network printers, fax printers and PDF writers, without changes to the original applications.

You can set your application to print to an ascii file, or you can let Printfil capturing one or more parallel ports (PRN: , LPT1: to LPT9:), automatically redirecting your print jobs to any printer, even to a printer which is physically connected to the captured port or if no LPT ports are physically installed on your PC.
