PrnAdmin is written in VBScript, and its file name is Prnmgr.vbs.

PrnAdmin performs these functions:

Adds or deletes the following:
- Local or remote printers.
- Printer connections.
- Local or remote forms.
- Ports on local or remote servers.
- Printer drivers on local or remote servers.
Enumerates ports, drivers, printers, or forms on local or remote printers.
Pauses, resumes, or clears the print jobs of a local or remote printer.
Configures a local or remote printer.

To find more information about PrnAdmin, see “Resource Kit Tools Help” in the Tools and Settings Collection.

Network Printing Registry Entries

The Windows platforms that use these registry entries and subkeys are noted in the Version portion of the listings. Many registry elements that are noted as being for Windows XP and Windows Server 2003 might also work on older versions of Windows; check documentation specifically for those versions for more details.

The information here is provided as a reference for use in troubleshooting or verifying that the required settings are applied. It is recommended that you do not directly edit the registry unless there is no other alternative. Modifications to the registry are not validated by the registry editor or by Windows before they are applied, and as a result, incorrect values can be stored. This can result in unrecoverable errors in the system. When possible, use Group Policy or other Windows tools, such as Microsoft Management Console (MMC), to accomplish tasks rather than editing the registry directly. If you must edit the registry, use extreme caution.

The following registry entries and subkeys are associated with Network Printing.

Network Printing Group Policy Settings

The following table lists and describes the Group Policy settings that are associated with Network Printing.

Group Policy Settings Associated with Network Printing

Group Policy Setting	Description
Allow printers to be published	Determines whether the computer’s shared printers can be published in Active Directory.
Disallow installation of printers that use kernel-mode drivers	Determines whether printers using kernel-mode drivers can be installed on the local computer. If enabled, prevents a printer that is using kernel-mode drivers from being installed on the local computer.
Automatically publish new printers in Active Directory	Determines whether the Add Printer Wizard automatically publishes the computer’s shared printers in Active Directory.
Allow pruning of published printers	Determines whether the domain controller can prune (delete from Active Directory) the printers published by this computer.
Printer browsing	Announces the presence of shared printers to print browse master servers when Active Directory is not available.
Prune printers that are not automatically republished	Determines whether the system prunes printers that are not automatically republished. (Applies to printers running on operating systems other than Windows 2000 or Windows Server 2003. Also applies to printers running on Windows 2000 or Windows Server 2003 that are published outside of their domain.)
Directory pruning interval	Specifies how often the pruning service on a domain controller contacts computers to verify that their printers are operational.
Directory pruning retry	Specifies how many times the pruning service on a domain controller repeats its attempt to contact a computer before pruning the computer’s printers.
Directory pruning priority	Sets the priority of the pruning thread.
Check published state	Directs the system to periodically verify that printers published by this computer still appear in Active Directory. Also specifies how often the system repeats verification.
Web-based printing	Determines whether Internet printing is supported on this server. (If you disable this policy, Internet printing is not supported.)
Custom support URL in the Printers and Faxes folder	Adds a customized Web page link to the Printers and Faxes folder. By default, the Printers and Faxes folder includes a link to the Microsoft Support Web page or to the Web page for the vendor of the currently selected printer. You can use this policy to replace the default link with a link to your organization’s Web page.
Computer location	Specifies the default location criteria used when searching for printers.
Pre-populate printer search location text	Enables the physical Location Tracking support feature of Windows Server 2003 printers. If you disable this policy or do not configure it, Location Tracking is disabled. Printer proximity is estimated based on IP address and subnet mask.
Allow print spooler to accept client connections	Determines how clients access the print server over the network. By default, this policy setting automatically enables connections upon creation of the first shared printer or clustered server spooler resource.
Point and Print restrictions	Restricts a client computer’s ability to connect to and install a printer driver from print servers. By default, this policy setting allows managed clients to use Point and Print only with servers within their forest. An administrator can use this setting to add servers to the list of trusted print servers. Disabling this setting enables connections to any accessible print server.

Network Ports Used by Network Printing

The following table lists services used in network printing and the protocols they provide in the network printing process. Not all services are installed or active at all times, and the protocols used in network printing depend on the type of clients submitting jobs to the print server.

Port Assignments for Network Printing

Service Name	UDP	TCP
Services for Macintosh (uses AppleTalk)	201, 202, 204, 206	201, 202, 204, 206
Internet Printing Protocol (uses HTTP)	80	80
NWLink (uses IPX/SPX)	213	213
LPDSVC (accepts LPR)	515	515
LPR Port (sends LPR)	721-731, >1023	721-731, >1023
Server (using SMB)	137, 138	139
Server (using RPC)	530	530
Standard Port Monitor (using SNMP)	161, 162	161, 162
Standard Port Monitor (using LPR)	> 1023	> 1023
Standard Port Monitor (using RAW)	2000, 2501-2503, 3001, 6869, >=9100	2000, 2501, 2503, 3001, 6869, >=9100

Standard LPR, according to RFC 1179 from the Internet Engineering Task Force, uses ports 721 through 731 to send data. However, Windows Server 2003 can be configured on a per-port or per-server basis to use port number higher than 1023 for sending data with LPR.

Also different from RFC 1179 is the standard port monitor, which sends documents to a printer by using either the RAW or LPR printing protocol. Together, these protocols support most current TCP/IP printers.

The RAW protocol is the default print protocol for most print devices. To send a job formatted with RAW, the print server opens a TCP stream to the printer's port 9100 or another port number and selects the connections to multiport external devices. For example, on certain print devices port 9101 goes to the first parallel port, 9102 goes to the second parallel port, and so on.

The standard port monitor uses the LPR protocol when you specify LPR protocol during port installation or reconfiguration, or when the RAW protocol cannot be established.

The standard port monitor deviates from the LPR standard in the following ways:

The standard port monitor does not conform to the RFC 1179 requirement that the source TCP port must lie between port 721 and port 731. The standard port monitor uses ports from the general, unreserved pool of ports (1024 and above).
The standard port monitor sends a print job to the spooler without determining the actual job size and designates a default job size, regardless of the actual size of the job. The LPR standard states that print jobs must include information about the size of the job the port monitor sends. Sending a print job that contains job size information requires that the port monitor spool the job twice — once to determine size, and once to send the job to the spooler. Spooling the job once, by using the standard port monitor, improves printing performance.
