By default PaperCut NG/MF runs an internal web server on port 9191 (HTTP) and 9192 (HTTPS).
You can change the Application ServerAn Application Server is the primary server program responsible for providing the PaperCut user interface, storing data, and providing services to users. PaperCut uses the Application Server to manage user and account information, manage printers, calculate print costs, provide a web browser interface to administrators and end users, and much more. port from 9191/9192 to any other value, such as 80/ 443. For more information, see Enable ports 80 (HTTP) and 443 (HTTPS).
If you change the Application Server port, you must also change the port number in the applications that connect to the server. i.e, the Print ProviderA Print Provider is a monitoring service installed on a secondary print server to allow PaperCut to control and track printers. This monitoring component intercepts the local printing and reports the use back to the primary Application Server. and the User ClientThe User Client tool is an add-on that resides on a user's desktop. It allows users to view their current account balance via a popup window, provides users with the opportunity to confirm what they are about to print, allows users to select shared accounts via a popup, if administrators have granted access to this feature, and displays system messages, such as the "low credit" warning message or print policy popups..
Application Server connections
The following components connect to and from the Application Server:
- Admin web interface
- User web interfaceThe User web interface provide a range of services for users, including a summary of usage and balance history, a list of the shared accounts that the user can use for printing, the current costs for printing usage, ability to add balance by using a TopUp/Pre-Paid Card or an external payment system (when using the payment gateway module), transfer funds to other users, view a history of balance transactions, view a list of the user's recent printing, and view print jobs pending release (when using a Release Station).
- Web CashierWeb Cashier is a basic Point of Sale (POS) system to charge items to PaperCut accounts and deposit funds into users' accounts.
- Payment Gateway Module
- Site Servers
- MFD/printer (port 9193 for device RPC—used only for embedded copier/MFP solutions)
The following components connect to the Application Server:
- Print Provider (secondary serverA PaperCut secondary server is a system that directly hosts a printer, that is, a print server with a Print Provider installed. A secondary server can be a server style system hosting many printers, a desktop style system hosting printer(s) also shared to other network users, or a desktop style system with the printer used only for local users (not shared).)
- Standard Release StationPrint Release Stations place a print job on hold and allow users to release it when required. Often a Release Station is a dedicated PC terminal located next to the printers, however, Release Stations can take other forms such as a web browser based interface. Some common examples where Release Stations can be used include secure printing, approved printing, and authentication. In a secure printing environment jobs are only printed when the user arrives at the print area and confirms his or her identity. This ensures the user is there to collect the job and other users can't "accidentally" collect the document. In some organizations it may be appropriate to hold jobs until they are approved by selected individuals. A good example would be a teacher approving printing on an expensive color printer. Hold/Release queues can be used as a form of authentication in an unauthenticated environment. Users must authenticate prior to releasing their jobs allowing PaperCut NG/MF to confirm their identity.
- User Client
- Mobility Print server
The Application Server connects to:
- User directories
All of the above clients need to be able to access this port on the server from across the entire network. If your organization uses firewalls between departments or campuses, then allow inbound HTTP and HTTPS connections on the designated ports to the PaperCut NG/MF Application Server.
