* Starts the creation of a new printer file, which will be deleted
* automatically once it has been closed and printed.
*
* 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.
*
* When the file is closed, it will be sent to the spooler and printed.
