 * This message is sent to create a new printer file which will be deleted

 * ================================== =================================
 *
 * UCHAR WordCount;                   Count of parameter words = 2
 * USHORT SetupLength;                Length of printer setup data
 * USHORT Mode;                       0 = Text mode (DOS expands TABs)
 *                                     1 = Graphics mode

 * UCHAR BufferFormat;                0x04
 * STRING IdentifierString[];         Identifier string
 *
 * Tid in the SMB header must refer to a printer resource type.
 *
 * SetupLength is the number of bytes in the first part of the resulting
 * print spool file which contains printer-specific control strings.
 *
 * Mode can have the following values:
 *
 *      0     Text mode.  The server may optionally
 *            expand tabs to a series of spaces.
 *      1     Graphics mode.  No conversion of data
 *            should be done by the server.
 *
 * IdentifierString can be used by the server to provide some sort of per-
 * client identifying component to the print file.

 * USHORT ByteCount;                  Count of data bytes = 0
 *
 * Fid is the returned handle which may be used by subsequent write and
 * close operations.  When the file is finally closed, it will be sent to
