-The CBM 8023P printer source code (1980). Extracted from 8023p-printer-source.d64 from Steve Gray's [Dennis Jarvis Page](http://6502.org/users/sjgray/dj/) and converted to LF line breaks and LST-style indenting.

Extracted from 8023p-printer-source.d64 from Steve Gray's [Dennis Jarvis Page](http://6502.org/users/sjgray/dj/) and converted to LF line breaks and LST-style indenting. The `.NOLIST` directive was commented out in `us.ptr.src`, so building would create a useful LST file.
 
-The CBM 8023P is a dot matrix printer with an IEEE-488 connection, a 6502/6532-based controller, and a Brother M82 machanism. The source contains references to Epson Model 3110/3210 mechanisms which seem to have been used in earlier printers.
