How were newspapers printed in the 1900s and what technologies were commonly used for the printing process during that time?

Newspapers in the 1900s were typically printed using a process called letterpress printing. This involved setting individual metal type characters onto a press, inking them, and then pressing them onto paper. Common technologies used for printing during that time included linotype machines for setting type, rotary presses for printing at high speeds, and stereotyping for creating printing plates.
