I have two LA100ro as they proved in the field to be rugged and I got to
see that from the point of view of DEC printers engineering. The curious
approach to "18pin" printing was twofold. One was to allow fast draft
quality printing and the other was rugged high quality printing that could
still punch multipart forms with a known reliable head. At that time there
were a few 18 pin heads but they didn't have the long term life at sustained
high print rates. Note, this is a 1984-5 design so understand that many
printers at that time were of smaller or less rugged style or really
The LA100RO is most valuable to businesses that still used wide pinfed (assuming
you have the forms tractor) multipart forms.
In the high quality mode it does print decently and the graphics printing is
not as slow as some dot matrix were.
