Ok, I've worked my way through the dumps, and I've learned a few more 
things:

ESC(D == 40 38 50 14  (== printhead res 180*720)
ESC(i == 00           (== default weave?)
ESC(S == d4 10 00 00 64 23 52 00 (== 6" width, 7480" length!)
FP 03 00  00 ec 00    (== zero margin offset of -19, or -0.75mm)

HQ mode:
 ESC(U == 02 02 01 a0 05 == 1440dpi base, 720p, 720v, 1440h
 ESC(m == 70     (PrintMethod in media tables)
 ESC(e == 00 23  (escp2_ink_type in resolutions table, == 35pl?)
Standard mode:
 ESC(U == 02 02 02 a0 05 (== 1440dpi base, 720p, 720v, 720h)
 ESC(m == 50
 ESC(e == 00 22  (== 34)
Fast mode:
 ESC(U == 04 04 02 a0 05 (== 1440dpi base, 360p, 360v, 720h)
 ESC(m == 40
 ESC(e == 00 21 (== 33)

There are no "PP", "PM", "MI", "EX", or "SN" remote commands in the 
dumps, nor anything that indicates explicit print size or cutter 
control, just the typical ESCi ESC(v, ESC($ sequences until the "JE" 
command after a form feed which I presume cuts+ejects the print.

Also, I see these in the dump, but I haven't found how to interpret yet:

   HD 03 00  00 03 02           # set driver info ?
   LB 03 00  00 01 01           # sent before FP

   1b  (  g 04 00  30 2d 00 00  # seen right before image data starts

I can insert the LB sequence into an inputslots InitSequence, but I'm 
not sure what to do about that ESC(g sequence.
