Before the smaller dot matrix printers that were starting to appear in the late 70's,
most printing was done on devices like these:


Friden Flexowriter (eg LGP-30) - like a typewriter. Very early days.  Had interesting characters supported.

Diablo (daisywheel)           - most of the Edinburgh CSR's were printed on these.  Multiple wheels availble.

IBM 6400 (shuttle matrix printer) 1500 lines per minute.  The Algol-W printout appears to be from a shuttle matrix.

IBM 1402 (band printer)  - same tech as the Data Products 2260 we had in the machine halls at Edinburgh.
                           These printers fed paper through so fast it would fountain up into the air.

- those devices are the sorts that this project hopes to support.  I'll try to ensure we
have test samples from as many different technolgies as I can locate.
