/* Sony UP-DR150/UP-DR200 Spool file format
The spool file is a series of 4-byte commands, followed by optional
arguments. The purpose of the commands is unknown, but they presumably
instruct the driver to perform certain things.
If you treat these 4 bytes as a 32-bit little-endian number, if the most significant
four bits are bits are non-zero, the value is is to be interpreted as a driver
command. If the most significant bits are zero, the value signifies that the following
N bytes of data should be sent to the printer as-is.
Known driver "commands":
6a ff ff ff
fc ff ff ff
fb ff ff ff
f4 ff ff ff
ed ff ff ff
f9 ff ff ff
f8 ff ff ff
ec ff ff ff
eb ff ff ff
fa ff ff ff
f3 ff ff ff
ef ff ff ff XX 00 00 00 # XX == print size (0x01/0x02/0x03/0x04)
f5 ff ff ff YY 00 00 00 # YY == ??? (seen 0x01)
All printer commands start with 0x1b, and are at least 7 bytes long.
************************************************************************
The data stream sent to the printer consists of all the commands in the
spool file, plus a couple other ones that generate responses. It is
unknown if those additional commands are necessary. This is a typical
sequence:
[[ Sniff start of a UP-DR150 ]]

-> 0e 00 00 00 00 00 00 00 00 04 a8 08 0a a4 00
<- 1b 16 00 00 00 00 00
-> "reset" ??
[[ begin job ]]
<- 1b ef 00 00 00 06 00
