revisitor/ricoh-sp100 — reverse-engineered prompt

Build me a simple Linux printer driver package for Ricoh Aficio SP printers that helps people get these older Ricoh SP models working with CUPS.

I want it to include the needed CUPS filter scripts for the supported printer families, PPD files for the matching printer models, and a small requirements check script that tells the user what packages or tools are missing before they install. It should also include a USB reset helper for the common issue where the printer works once and then stops printing.

Please make it easy for a normal Linux user to follow from the terminal. Include clear install instructions in the README for copying the right filter depending on the printer model, setting the correct permissions and ownership, adding the printer through the CUPS web interface, selecting the matching PPD, printing a test page, and using the USB reset script if needed. Keep it lightweight and shell based.
