Hard Resource Sharing Concepts

(Printer Sharing)

Module Objectives

• Basics of hard resource sharing• Placing a printer for sharing• The concept of creating a printer• Printer installation notes• The concept of logical printers• Viewing logical printers as print

queues

Hard Resource Sharing

• Install the resource on the server• Place the hard resource for

network sharing• Install the hard resource as a

networked device from a client for sharing

Placing a Printer for Sharing

• Create the printer on the server using Add Printer module on the server

• Place the printer on the network for sharing– It can be placed for sharing during installation– Or by following the steps as in placing a soft

resource such as directory for sharing

• Define printer access permissions• Set other printer properties

Printer Installation Notes

• In Microsoft NT, the printer is installed as a logical printer– More details are presented when logical

connections are explained• In one aspect, network installation is

different from single user installation– Printer driver for all the different client

operating systems on the network also need to be installed

Notes on Printer Creation

• Printer drivers for all the client operating systems on the network may be stored for the client’s convenience – A path to the directory containing the drivers

need to be specified during installation

• Following the creation of the printer, the Icon for the printer will appear with a hand holding the printer in the Printers window

MODULE

Placing an Installed Printer for Sharing

Module Objectives

• Overview of placing a printer for sharing

• A note on sharing• Placing a printer for sharing

– Case example– Steps– Demonstration

Placing a Printer for Sharing

• If a printer is already designated to be shared during installation, it need not be placed for sharing at this tim

• If an existing unshared printer connected to the server is to be shared, then it must be placed for sharing explicitly

A Note on Share

• Assigning long share names may prevent some MS-DOS machines on the network from accessing the printer

• If MS-DOS machines are serviced on the network, it is desirable to assign a name conforming to the DOS 8.3 naming format

Case Example for Placing a Printer for Sharing

Printer Security

Module Objectives

• Focus on security issues• Printer permission• Listing of access permissions to the printer• Permissions and privileges

– No access and simple printer access

• Manage documents privilege• Full control privilege• Understanding the processing of

documents by printers

Security Issues

Permissions

Auditing Ownership

Security Issues

• Permission– Permission to use the printer

• Audit– Events such as print, changing

permissions etc. can be audited

• Ownership– Taking ownership of the printer

Printer Permission

• As in the case of a soft resource, permission can also be given to users for the use of the printer

• Permission must be given to a user or a group of users before they could connect to the networked printer for usage

Access Permissions to the Printer

No Access Print

ManageDocuments

Full Control

Permissions and Privileges

• No Access – Denies access to the printer

• Printer– Allows the user to print on the printer

• Manage Documents and Full Control enable the user to control the printer

Manage Documents

• Settings on the document can be changed

• Control on the printing process– Pause– Resume– Restart– Delete

• Controls are exercised at the document level

Full Control

• At the (logical) printer level– Change document order of printing– Pause, resume and purge– Change properties– Change permissions– Delete printers

• At the document level, all the privileges available under Manage Documents are also available here

MODULE

Giving Permission to Use the Printer

Module Objectives

• Printer permission case scenario• Giving permission to

access/manage a printer– Case example– Steps– Demonstration

A Scenario in Printer Permissions

Everyone(Print)

Inspectors(Manage Documents)

Print Operators(Full Control)

Giving Permission to Access/Manage the Printer:

Case Example

• Everyone– Print permission

• Inspectors– Manage documents

• Because Everyone is given print permission when a logical printer is created, only the inspectors need to be given the Manage Document permission

Giving Permission to Manage the Documents:

Steps
