[Gimp-print-devel] horizontal motion?

[<sh...@al...>]

Ok, I'm trying to follow the horizontal print head motions.  Here's a
section of ESCP2 output from gimp-print:

00000008  1b  (  U 05 00 02 02 01 a0 05 
       :
00000048  1b  (  V 04 00 00 00 00 00 
00000051  1b  (  r 02 00 00 02 
00000058  1b  \ a6 ff 
0000005c  1b  . 01 05 05 01 be 05  (1470, 1) *0d 
0000010c  1b  (  r 02 00 00 01 
00000113  1b  \ a6 ff 
00000117  1b  . 01 05 05 01 be 05  (1470, 1) *0d 
00000176  1b  (  r 02 00 00 04 
0000017d  1b  \ a6 ff 
00000181  1b  . 01 05 05 01 be 05  (1470, 1) *0d 
00000245  1b  (  r 02 00 01 02 
0000024c  1b  \ a6 ff 

Roughly translated to English it's:

Use 1/720" page 1/720" vertical and 1/1440" horizontal units
  :
Move to top of page
Select color cyan
Move left 90*1/1440"
Print at 720 DPI one line of 1470 pixels with an extra 0xd at the end (???)
Select color magenta
Move left 90*1/1440"
Print at 720 DPI one line of 1470 pixels with an extra 0xd at the end (???)
etc.

My question is, why is it only moving 90 ticks to the left when it's printing
2940 ticks to the right?  The printer head should hit the right edge of the
page in no time this way, no?  What am I missing?

And why does the relative motion preceed the printing?  Should it come
afterward?
