/* Sony UP-DR150 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.
Known 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)
Additionally, if the leading 4 bits of the command are 0, it signifies
that what follows are data bytes to be sent to the printer.
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 ]]
<- 1b e0 00 00 00 0f 00
-> 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
-> 05 00 00 00 00 22
<- 1b e5 00 00 00 08 00 ** In spool file
