Kris,

FWIW,  twenty-five years ago - when I was *very* heavily into 
assembler/disassembler - I had a Qume Daisywheel printer [cost about as 
much as an entire present-day SMP system running on twin 64-bit CPUs, in 
the days when a (10" x 6") 64_KB_ DRAM cost US$750.00] and I was able 
programatically to draw graphs on that Daisy-wheel printer just using 
the *dot* ["."] and controlling the rotation of the printer's platen and 
the horizontal head positioning to 1/144th of an inch, by learning all 
the escape codes for that printer. When I later had a Texas Instruments 
TI-855 with three slots for different font families,  in multiple sytles 
- super-condensed to extra-large - I was able to do a screen-dump that 
matched the memory-mapped terminal display exactly - and I could print 
landscape on it, interactively - I could spin the platen etc., just 
using the keyboard's arrow keys. That was around 23 years ago, in the 
days when commercial printer drivers were very generic, and had few 
features - so no, you don't *have* to use an OS-specific printer-driver 
to output traffic on a printer.
