If your server or client machines are running Windows XP Professional you must ensure that each has 'simple file sharing' disabled. Otherwise, they will not be able to authenticate to the PaperCut NG server (as they try to authenticate as the Guest user). To disable 'simple file sharing', for each of your machines running Windows XP Professional:

Windows XP Home uses 'simple file sharing', forcing client machines to try to authenticate as the Guest user. For this reason, we do not recommend the use of Windows XP Home in multi-user environments.

Users may still authenticate with PaperCut NG on Windows XP Home by entering their details into the User Client utility. This is similar to how user authentication is performed with Mac clients. For more information see the section called “Scenario Two: The Multi-User Mac with Popup Authentication”.

There are two main causes of this problem:

PaperCut NG currently supports about 90% of printers on the market. If a printer's language is not recognized, PaperCut NG will not detect any pages and record the print job as a zero page count. This is usually accompanied with an error message in the Application Event Log. We recommend you try the following problem resolution actions in this order:

The Print Provider may be configured via its configuration to ignore a printer. For more information see the section called “Ignoring/Deleting a printer”.

PaperCut NG will format the currency based off the operating system's default regional settings. If the default regional settings are incorrect, the format can be changed by defining your location under Options → General → Display Settings → Location.

There are a number of possible explanations. The first step is to open the Print Provider's log file on the secondary server. This file will often contain error messages indicating the cause or type of error. On a Windows system the log file is located at: [app-dir]\providers\print\win\print-provider.log The file can be opened from any text editor such as Notepad.

Some common issues are:

The client software needs to contact the application server. For the technical readers, the client makes an XML web services request to the server on port 9191. Most problems relate to either firewalls blocking access or the application server's name is not correctly defined. Ensure that:

The admin user's password is set up on initial install during the configuration wizard. This password can be changed post-install by editing the text file located at [app_dir]/server/server.properties. The password is defined in the property admin.password.

PaperCut NG is primarily designed for networks managed under a domain and/or authenticated environments. Peer-to-peer networks or Workgroups are however supported. The first option should be to consider requiring users to log onto the workstations using their username and password. If this is not possible, an alternate option is to set up the user accounts on system hosting the printers (system running the PaperCut NG server software) and configuring the account selection popup with the Charge to other users option selected. Users can then enter their username and password in the popup that displays each time they print.

Yes. The client software can be started minimized by executing the program with a command-line switch -minimized. See the section called “User Client Options”.

If the user running the client software is configured to either:

the client software must be running at all times. If the user is configured in either of these modes, the client software's exit option is disabled. Note: The client software will need to be restarted to pick up this option after the user's options have been changed.

PaperCut NG caches group membership by replicating the user/group relationship structure internally in the system. Typically network group membership is relatively static, and is usually set up when a user account is initially created. PaperCut NG tries to be a good network application by avoiding common no-no's such as flooding domain controllers with group lookup requests. This is achieved by caching. Operations such as Bulk user operations, quota allocations, group reports and group filtering all need to do group membership lookups. Caching speeds up these operations and prevents excessive callouts to the domain servers.

The downside to caching is that group membership changes are not immediately reflected inside PaperCut NG. To force PaperCut NG to detect the change perform a User/Group synchronization under the Options section. The system will also automatically refresh group membership overnight during low network activity.

The config area contains all of the PaperCut NG system wide settings. Some of these can be changed via the normal options interface while others are designed for internal developer use and tuning and are only accessible via the config editor. Any changes made in the config editor should be done with care as an invalid entry may require you to reinstall the system!

One of the business objectives of PaperCut NG was openness. The development team actually encourages this and can assist with detailed API documentation and source code. If you would like feedback on your ideas, please email our support team. They would be more than happy offer advice.

Running PaperCut NG on top of an external database is an advanced option. This is discussed in details in system management section.

PaperCut NG's internal database is Apache Derby - an open source database written by IBM and based on IBM's DB2 Cloudscape database system. The internal database has proven to scale very well and is suitable for networks of all sizes.

PaperCut NG is developed under a number of languages and development environments. The printer monitoring component and other native operating system interfaces such as user authentication are written in C/C++. The application server and web services are written in server-side Java.

The PaperCut NG is designed as a cluster compatible application and supports clustering at all layers of the application. For more information on configuring PaperCut NG in a Microsoft Cluster environment, please see Chapter 16, Microsoft Cluster Environments. If you'd like to investigate clustering options on other platforms (Linux) please contact our support team.
