It actually breaks the Shinko s2145, and given that none of these printers comply with the USBLP class anyway, it's no real loss.

/* 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:
