This software enables printing from DOS, Unix, and Linux to a range of Windows printers including USB, GDI, PDF, email, network, IP, fax, and virtual. It also captures and redirects print jobs from LPT1: to LPT9: ports, enabling printing to printers without physical LPT ports via the captured port.

One of the key features of Printfil is its ability to capture data from parallel ports or disk files and redirect print jobs to any Windows printer. This means that even if the printer physically connected to the captured port does not have any LPT ports installed, Printfil can still handle the printing process. Additionally, the software provides various advanced features such as including logos or images from separate files, using specialized windows fonts (e.g., barcodes), colorizing the text, and previewing the printing output.
Another noteworthy aspect of Printfil is its compatibility with any printer installed on the Windows Control Panel. It supports printing to USB, GDI, Windows-only, and Virtual printers. Furthermore, it allows users to print A4 landscape sheets instead of using dot-matrix 136-column printers. Users can also send DOS print jobs via fax using third-party fax software or export print jobs in PDF format with encryption and password protection. These PDF files can then be sent via email using the user's preferred email client program or an SMTP server, with or without user intervention.
Printfil is highly customizable as it utilizes a single set of customizable escape sequences for all printers, regardless of their make, model, or emulation. It also offers the ability to print complex jobs to legacy printers in RAW mode, such as graphs and drawings, as well as fast printing on matrix printers, reminiscent of the DOS era. Additionally, users have the option to archive copies of all captured jobs and print to multiple printers simultaneously.
One of Printfil's biggest advantages is that it seamlessly integrates with existing applications, without any modifications required. Whether running host-based programs like Unix on a Windows Terminal Emulator or dealing with transparent-print characters and different printer settings, Printfil can effortlessly handle these challenges. It can easily assimilate with a shared file system (NFS, SCO-VisionFS, Samba, etc.) or a Terminal Emulator, making it an indispensable tool for all printing needs.
