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: and from 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. it allows also: - preview printing - include logos or other images stored in separate files - colorize the text - print a4 landscape sheets in place of printing on dot-matrix 136-column printers - print to any printer installed on the windows control panel, including usb, gdi, windows-only and virtual printers - send print jobs via fax (using any third-party fax software which acts like a printer - eg. microsoft fax - or a multifunction - all-in-one - printer) - use specialist windows fonts (barcodes, for instance) as well as normal characters - export print jobs in pdf format, with or without user intervention, even with encryption and password protection - send print jobs via e-mail by using your own e-mail client program, with or without user intervention - use a single, customizable set of escape sequences for all printers, regardless of make, model and emulation provided (if any, as for gdi printers) - print complex jobs to legacy printers in raw mode (graphs, drawings) - archive a copy of all the captured jobs - use multiple printers simultaneously all this without changes to your applications if you are developing host based applications (like unix) to run on a windows terminal emulator, you can stop battling with transparent-print characters and different settings for different printers. all you need is a shared file system (nfs, sco-visionfs, samba and others) to store output for your print jobs and printfil.
