About the Plotters
The machine itself contributes to the final look. Movement, buffer limits, pen contact, paper handling, and line start-stop behavior all matter.
Plotter
HP 7475A
Larger HP plotter with more room for bigger plotted pieces.
Plotter
HP 7440A
Useful HP platform for plotting and experimentation.
Plotter
TAXAN KPL710
Larger-format machine with different paper possibilities and workflow considerations.
Communication
FTDI is not the whole story
Modern USB bridging helps, but baud rate, wiring, serial settings, and handshaking still matter.
Workflow
Why handshaking matters
Older plotters can be sensitive to timing and buffer limits. Simple HPGL and safe sender behavior matter.
Where CNC fits
CNC belongs here mainly as a teaching comparison. Plotters often depend on serial behavior and handshaking. CNC workflows are usually more controller-defined and software-mapped.
