Throughput was measured in linear feet per second and that number had almost 3 digits. Wide carriage dot matrix that was a head the full width of the paper path so no movement required except by the paper. Paper delivered by forklift. <br>At around 90 feet per second the refold was by air jets.<br>I was asked to fix the serial port connection feeding one of these. Testing wasted at least a tree. Finally found rodent damage in a wall. The other printers were next to fail. Reran new wires through a 3" steel conduit in the wall and capped off. Swapped over each end and got paid. Got called back when they switched to ethernet from serial. They were super happy I had run cat 5 as the change was new ends plus a switch.<br><br><div class="gmail_quote">On September 22, 2020 11:59:15 AM EDT, Solomon Peachy via Ale <ale@ale.org> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
