I am happy to publish the beta version of YPRT, the Serial printer ROM for the HP41CL. It is a heavily patched version of the standard PRINTER 1E ROM for the HP82143, and uses Diego's USB-82143A emulator (sorry, only runs under Windows).
It is a 2-bank ROM that must be plugged in Page 6. Please read the instructions for installation, limitations and pitfalls. So far I have only tested this myself, use is at your own risk.
Please report any issues by email, a private message in this forum or in this thread (preferred, so we can all benefit).

Downloads are in the HP41C Software Library (in the forum) in a single ZIP file with the 2 ROM files and documentation.

Possible issue detected: YPRT may disturb the Extended CATalag function of the AMMC-OSX ROM. Will dive into this.

Issue fixed. New ROM for Bank 1 issued.
The entry points for Pause and IO Service have been removed. These bascially only check for the printer keys, which are not relevant for the printer emulator.
