HP provides a downloadable "driver" for Linux for the HP 107w printer but there are NO reasonable install instructions provided, and following the "obvious" install process did not get the printer working.

The closest I found to HP install instuctions once I knew more is https://support.hp.com/in-en/document/c05588857

Since I found this annoying and wasted more time on getting this printer working under Linux, I'm sharing a summary of what did work (on Debian 10).

1. Download the driver file from https://support.hp.com/us-en/drivers/selfservice/hp-laser-100-printer-series/24494339/model/24494342    from under the "Basic Drivers" menu for when the OS is set to Linux.

The current version now is: "HP Laser 100 and HP Color Laser 150 Printer series Print Driver V1.00.39:00.12	5.9 MB	Mar 20, 2019"

Lsyncd Technical Session

So what is lsyncd?

Lsyncd is a tool used to keep a source directory in sync with other local or remote directories. It is a solution suited keeping directories in sync by batch processing changes over to the synced directories.

When would we use lsyncd?

So the generic use case is to keep a source directory in sync with one or more local and remote directories.
