Basic spool file format:
TT RR NN 00 XX XX XX XX 00 00 00 00 <- FILE header.
NN : copies (0x01 or more)
RR : resolution; 0 == 334 dpi, 1 == 600dpi
TT : type 0x02 == 4x6, 0x01 == 5x3.5
XX XX XX XX : plane length (LE)
plane length * 3 + 12 == file length.
Followed by three planes, each with this header:
28 00 00 00 00 08 00 00 RR RR 00 00 01 00 08 00
00 00 00 00 00 00 00 00 5a 33 00 00 YY YY 00 00
00 01 00 00 00 00 00 00
RR RR : rows in LE format
YY YY : 0x335a (334dpi) or 0x5c40 (600dpi)
Followed by 1024 bytes of color tables:
ff ff ff 00 ... 00 00 00 00
1024+40 = 1064 bytes of header per plane.
Always have 2048 columns of data.
followed by (2048 * rows) bytes of data.
