/* Kodak 6800/6850 data format
Spool file consists of 17-byte header followed by plane-interleaved BGR data.
Native printer resolution is 1844 pixels per row, and 1240 or 2434 rows.
6850 Adds support for 5x7, with 1548 pixels per row and 2140 columns.
Header:
03 1b 43 48 43 0a 00 01 00 Fixed header
NN Number of copies (01-255)
WW WW Number of columns, big endian. (Fixed at 1844 on 6800)
HH HH Number of rows, big endian.
SS 0x00 (4x6) 0x06 (8x6) 0x07 (5x7 on 6850)
LL Laminate, 0x00 (off) or 0x01 (on)
UU 0x01 for multi-cut, 0x00 otherwise.
Note: For 4x6 prints on 6x8 media, print size (SS) is set to 0x06 and the
final octet is set to 0x01.
