While falling over Sun and DEC manuals I also found a complete set of
manuals for a great and massive Data Printer Corporation line printer
in four volumes:
Data Printer Corp Chaintrain Line Printer
Models CT-4964 CT-6644 CT-7484
parts and diagrams
operating
maintenance
principles of operation
Yours for the postage but I doubt anybody wants them.

I defer to Al K first, but I will take them on for scanning, if
they're not already online.

I had a 133 column line printer, and an 80 column Data Printer, Data
products interfaces. Both drums. They could both move 3 x 5 cards at
10000+ lines / min when printing < 20 columns. They were variable
speed, so when something fired on the first 20 columns, such as for
addressing, the thing move like lighting.
Very nice printers. wish I could have held onto them, but they were
sold for good $$.
the 80 column one probably printed some junk mail for you, was bought by
a labeling company for a mass mailer of technical journals here in
Orange Country.
thanks

The early PDP11 line printers were like that (20 column buffer for the 80 column model; 24
column buffer for the 132 column model). Later on they apparently went to full line
buffering because the performance oddity you mentioned disappeared.
Speaking of printer widths, the Dutch computer company Electrologica was odd in that their
systems came with line printers that were 144 columns wide. I've never seen that
anywhere else.

The IBM 1443 printer, originally part of the 1440 system but available on
the 1800 system as well, was 144 columns wide. Type bar rather than a
train like the 1403; moved back and forth as hammers struck the desired
letter. Ugly ugly type face.
