46  * USHORT Mode;                       0 = Text mode (DOS expands TABs)

50  * STRING IdentifierString[];         Identifier string
51  *
52  * Tid in the SMB header must refer to a printer resource type.
53  *
54  * SetupLength is the number of bytes in the first part of the resulting
55  * print spool file which contains printer-specific control strings.
56  *
57  * Mode can have the following values:
58  *
59  *      0     Text mode.  The server may optionally
60  *            expand tabs to a series of spaces.
61  *      1     Graphics mode.  No conversion of data
62  *            should be done by the server.
63  *
64  * IdentifierString can be used by the server to provide some sort of per-
65  * client identifying component to the print file.
