- Contains: Support IEEE-1284 DeviceID as a CFString.
-
- Copyright 2000-2005 by Apple Computer, Inc., all rights reserved.
-
- Description:
- IEEE-1284 Device ID is referenced in USB and PPDT (1394.3). It allows
- a computer peripheral to convey information about its required software
- to the host system.
-
- DeviceID is defined as a stream of ASCII bytes, commencing with one 16-bit
- binary integer in Little-Endian format which describes how many bytes
- of data are required by the entire DeviceID.
-
- The stream of bytes is further characterized as a series of
- key-value list pairs. In other words each key can be followed by one
- or more values. Multiple key-value list pairs fill out the DeviceID stream.
-
- Some keys are required: COMMAND SET (or CMD), MANUFACTURER (or MFG),
- and MODEL (or MDL).
-
- One needs to read the first two bytes of DeviceID to allocate storage
- for the complete DeviceID string. Then a second read operation can
- retrieve the entire string.
-
- Often DeviceID is not very large. By allocating a reasonable buffer one
- can fetch most device's DeviceID string on the first read.
-
- A more formal definition of DeviceID.
-
- <DeviceID> = <Length><Key_ValueList_Pair>+
-
- <Length> = <low byte of 16 bit integer><high byte of 16 bit integer>
- <Key_ValueList_Pair> = <Key>:<Value>[,<Value>]*;
-
- <Key> = <ASCII Byte>+
- <Value> = <ASCII Byte>+
-
- Some keys are defined in the standard. The standard specifies that
- keys are case sensitive. White space is allowed in the key.
-
- The standard does not say that values are case-sensitive.
- Lexmark is known to ship printers with mixed-case value:
- i.e., 'CLASS:Printer'
-
- Required Keys:
- 'COMMAND SET' or CMD
- MANUFACTURER or MFG
- MODEL or MDL
-
- Optional Keys:
- CLASS
- Value PRINTER is referenced in the standard.
-
- Observed Keys:
- SN,SERN
- Used by Hewlett-Packard for the serial number.

-
- A "persistent reference" is one which enables us to identify
- a printer regardless of where it resides on the USB topology,
- and enumeration sequence.
-
- To do this, we actually construct a reference from information
- buried inside the printer. First we look at the USB device
- descripton: an ideally defined device will support strings for
- manufacturer and product id, and serial number. The serial number
- will be unique for each printer.
-
- Our prefered identification fetches the IEEE-1284 device id string.
- This transparently handled IEEE-1284 compatible printers which
- connected over a USB-parallel cable. Only if we can't get all the
- information to uniquely identify the printer do we try the strings
- referenced in the printer's USB device descriptor. (These strings
- are typically absent in a USB-parallel cable.)
-
- If a device doesn't support serial numbers we have a problem:
- we can't distinguish between two identical printers. Unique serial
- numbers allow us to distinguish between two same-model, same-manufacturer
- USB printers.

- In:
- thePrinter iterator required for fetching device descriptor
- devRefNum required to configure the interface

- * @param string A CFStringRef of the string to be encoded.
- * @result An encoded CFString.

- * @discussion This function will change all characters in string into URL acceptable format
- * by encoding the text using the US-ASCII coded character set. The following
- * are invalid characters: the octets 00-1F, 7F, and 80-FF hex. Also called out
- * are the chars "<", ">", """, "#", "{", "}", "|", "\", "^", "~", "[", "]", "`".
- * The reserved characters for URL syntax are also to be encoded: (so don't pass
- * in a full URL here!) ";", "/", "?", ":", "@", "=", "%", and "&".
