Nice. I never seen a chain printer before.
Brings back memories for sure. On the first mainframe system I worked with
in the mid 80's we had to prevent anyone from entering lower case letters
into the IMS data bases because the chain printer only printed upper case
letters. If it encountered a lower case letter it left a blank. God
forbid someone forgot to do that when we created a new screen for data
entry. We had to change the screen edits to allow lower case when we
finally got a chain that could print both upper and lower case. I remember
how excited everyone was that we could now print in mixed case.
The first laser I worked with was a Xerox that was huge, like the size of
two desks stacked one on top of another. We were then able to print on
regular 8.5x11 paper, but we got complaints from accounting about it not
being green bar. I had to program the Xerox (it had its own language) to
print gray shaded bars like the green bar pin fed paper from the chain
printer. The computer operators were excited that we could insert a
colored sheet of paper for each new report and even multiple copies to make
it easier for them to route reports to the correct departments. No more
running pin fed paper through bursting machines and breaking apart reports.
