I have to simulate a LPT Printer for a legacy PC on 16b running MS DOS, from another host pc running windows, in order to capture the print job and further process it. There is no access to the legacy PC. Only physical access to the LPT port.

The connection between them is done with a LPT2USB tool. http://www.lpt2usb.net/

As I googled, printfil seems to be nearest as a solution. But I did not managed to simulate LPT printer with it.

I would like some ideas how to achieve this. (Commercial solutions or not).

Thank you for your time,

One way you should be able to achieve what you want is with a Parallel-to-Serial Converter. Attach the device to the parallel port of the old PC, instead of a printer. Then connect the other end to the serial port (remember those?) of another PC. If necessary, install a Serial Port PCI card. Then all you need is some software like a Terminal Emulator to read from the serial port.

You can capture the output of the legacy PC Parallel LPT port with hardware. Use a LPT cable to a capture PC, or parallel data recorder box hardware. Such cables/hardware is made by Photologic Ltd.

Example: Photologic Ltd. Model CS-ZN and Cables-To-Go Part#26886 lets you capture everything elegantly to a PC folder using Tera Term terminal emulator. It will save everything on the cable including graphics and protocol escape sequences. The transfer is quick as there is no mechanical printer burden.
