Directory Mapping Issues

Agenda

Look at IPP “Generic Directory Schema”

Look at SLPLook at LDAP


3

URIs

IPP printer-uri-supported (1setOf uri)

MANDATORY uri-security-supported (1setOf type2 keyword)

MANDATORY

SLP Single URL “ippurl = url as defined in IPP Model doc”

LDAP Can NOT have two attributes with parallel order, values Common solution: One Attribute: Val_1_1#Val_2_1,

Val_1_2#Val_2_2, etc.


4

Printer Name

IPP printer-name (name(127))

OPTIONAL (Why OPTIONAL??)

SLP name = STRING

# This attribute contains the name of the printer. It is a name that is more user friendly than the printer-URI. An administrator determines a printer's name and sets this attribute to that name. This name may be the last part of the printer's URI or it may be unrelated. In non-US-English locales, a name may contain characters that are not allowed in a URI.

LDAP OK


5

Printer Location

IPP printer-location (text (127))

OPTIONAL

SLP location-description = STRING O

#A free form description of this printer's physical location For example: "2nd floor, near the fire escape”

location-address = STRING O # Physical/Postal address for this device. Useful for nailing down

a group of printers in a very large corporate network. For example: 960 Main Street, San Jose, CA 95130

LDAP OK


6

Printer Description

IPP printer-info (text (127))

OPTIONAL

SLP description = STRING

# A free form string that can contain any site-specific descriptive information about this printer.

LDAP OK


7

Printer More Info

IPP printer-more-info (uri)

OPTIONAL

SLP printer-info = STRING L O

# A URI used to obtain more information about this specific printer. For example, this could be an HTTP type URI referencing an HTML page accessible to a Web Browser. The information obtained from this URI is intended for end user consumption. Features outside the scope of IPP can be accessed from this URI.

LDAP OK


8

Make and Model

IPP printer-make-and-model (text (127))

OPTIONAL

SLP make-model = STRING L O

# A simple text string defined by the manufacturer The syntax shall be: vendor-name "/" model-name where the vendor-name is the same as that registered with IANA for use in domain names. For example: "vendor-x/super-duper-printer".

LDAP OK


9

Document Formats Supported

IPP document-format-supported (1setOf mimeMediaType)

OPTIONAL

SLP document-format = STRING O M

# The format of the data to be printed. The standard values for this attribute are Internet Media types which are sometimes called MIME types.

LDAP OK


10

Color

IPP color-supported (boolean)

OPTIONAL

SLP color-supported = BOOLEAN O (false)

# Indicates whether color is supported

LDAP OK


11

Number-up supported

IPP number-up-supported (1setOf integer(0:MAX) |

rangeOfInteger(0:MAX)) OPTIONAL
