There are two ways of going about that: If you overflow the buffer your plotter will start behaving weird and it’ll probably try to indicate that an error happened. The terminal port is a bit more interesting, I read somewhere that it’s basically the same as the serial interface, only with a character echo, so you can send commands to the plotter per Telnet and see what you’re typing. Ok, let’s do that. It makes sense to enter abstract ‘steps’ rather than actual physical values.

If none of the above steps provide the solution, the problem is with the interface port on either the PC or the plotter. The force is probably not as hp 7550a plotter controlled through a feedback loop as the pen speed and is probably created by a simple duty cycle from the microprocessor, not by monitoring the actual force.
One p,otter that does interest hp 7550a plotter is making use of the programmable pen speed and pen force of the A. I got a working setup with the following configuration, but feel free to choose your own settings: Both plotters size media automatically so there are no 7550 to set on the plotters for the different paper sizes.
