Add and remove/delete/ignore printers

On Windows

PaperCut MF tracks all print queues local to the system by default. Local print queues are those that have been set up on the server running PaperCut MF with a local port, such as: a TCP/IP connection to a network printer, an LPRThe Line Printer Remote protocol (LPR) is a network protocol for submitting print jobs to a remote printer. A server for the LPD/LPR protocol listens for requests on TCP port 515. A request begins with a byte containing the request code, followed by the arguments to the request, and is terminated by an ASCII LF character. An LPD printer is identified by the IP address of the server machine and the queue name on that machine. Many different queue names may exist in one LPD server, with each queue having unique settings. The LPR software is installed on the client device. connection, or a printer attached locally via USB or LPT. Standard Windows print queues that are hosted on a different system, or re-shared, are not tracked (you can track these queues by setting up a secondary print serverA print server is a system responsible for hosting print queues and sharing printer resources to desktops. Users submit print jobs to a print server rather then directly to the printer itself. A print server can be a dedicated server but on many networks this server also performs other tasks, such as file serving, see Configuring secondary print servers and locally attached printers).

New print queues added to the system should show up automatically in PaperCut MF, however, in some rare situations the printer shows up only after the first print job is sent.

Under some situations you might not want to track all printers. Some examples of why an administrator might not want to monitor a printer include:

The printer is a virtual printerA virtual printer is a printer driver that resembles the functionalities of a physical printer, but is not actually associated with one. Instead, a virtual printer sends its output to a file, normally in PDF format or in other image formats like JPEG, TIFF or PostScript. A virtual printer acts similarly to a physical printer in that it transforms an electronic document into a form that can be easily read by the target user or device. In PaperCut, virtual printers are used for Find-Me printing. such as a PDF generator, FAX, or document management program.
The administrator might want to offer free printing on a selected printer and is not concerned with monitoring (silent monitoringIn silent monitoring mode, all users have unrestricted privilege so printing access is never denied. Papercut silently collects statistics on activity and its associated cost. All data is reportable and available in the Admin interface. Silent monitoring mode is popular in a business environment where management needs information on user activity. with a zero page cost also achieves this).
The printer might not be supported by PaperCut MF and needs to be ignored.

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. component is responsible for locating and tracking the printers. To instruct it to ignore a printer:

On the computer system hosting the queue to be added/removed/ignored, open the file [app_dir]\providers\print\win\print-provider.conf in a text editor such as Notepad.
Locate the line IgnorePrinters= and enter the full name of the printer on the right-hand-side of the equals line. For example:
IgnorePrinters=Office Printer
Note:
This is the printer's locally assigned name and not the name of its network share.
If you have multiple printers to ignore, then separate the each printer name with a comma. For example:
IgnorePrinters=Office Printer,Copy Room Printer
Wildcard expressions can also be used. Use '*' to ignore any span of characters, and '?' to ignore a single character. For example, to ignore any printers that start with the phrase Copy Room:
IgnorePrinters=Copy Room*
Restart (stop then start) the PaperCut Print Provider component under Start > Control Panel > Administrative Tools > Services
If the printer data is no longer required for reporting purposes:
1. Click the Printers tab.
  The Printer List page is displayed.
2. Select a printer.
  The Printer Details - Summary page is displayed.
3. In the Actions menu, click Delete this printer.
Test the changes by printing to the deleted printer and ensuring the printer does not re-register itself in the system. It if does, verify the name assigned under the IgnorePrinters= setting is correct.

On Mac

When you first install PaperCut MF, all printers are automatically added. However, any printers added to your network after installation must be manually added. Alternatively, you can change the configuration to automatically add new printers.

To automatically add any new printers in your network:

On the computer system hosting the queue to be added/removed/ignored, In a text editor such as Notepad, open the file:
[app_dir]\providers\print\mac\print-provider.conf .
Locate the line EnablePrinterAutoImport=off.
Change off to on.
Save the file.
Restart the 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)..

The service is called papercut-event-monitor on both Mac and Linux machines. This page explains how to restart the service: How to Enable Debug in the Print Provider.

The monitored printers are listed on the Printer List page. If the printers are not displayed, try printing a document. The first job triggers registration.

To manually add printers

The list of monitored printers is configured when installing PaperCut MF. To change the list of monitored printers, run the script at /Applications/PaperCut MF/Control Printer Monitoring.command. Read the script's instructions carefully and ensure that the Print Setup Utility is closed/quit when running this script.

After running the script, print a test document (i.e. using a text editor or printing a web page from Safari). The act of printing for the first time registers the printer with the primary server. Log in to PaperCut MF as admin and verify that the printers are now listed on the Printer List page. Perform a test print on each printer and verify that the jobs are tracked correctly.

Note:

At the technical level, Mac systems use the Common UNIX Printing System (CUPSCommon User Printing System (CUPS) is a printing system for Unix operating systems that allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer.). PaperCut MF tracks printing by integrating with CUPS. (For SysAdmins familiar with CUPS, PaperCut MF integrates by wrapping or proxying the CUPS backend). The Control Printer Monitoring.command script edits the file /etc/cups/printers.conf and prefixes the DeviceURI with papercut:, enabling monitoring on the selected printer. SysAdmins experienced with the terminal might prefer to edit the printers.conf file directly with a text editor. See On Linux for more details.

To delete a printer:

Double-click the Control Printer Monitoring.command script.
Choose to disable monitoring on the printer(s) to delete.
If the printer data is no longer required for reporting purposes:
1. Click the Printers tab.
  
  The Printer List page is displayed.
2. Select a printer.
  
  The Printer Details - Summary page is displayed.
3. In the Actions menu, click Delete this printer.
Test the changes by printing to the deleted printer and ensuring the printer does not re-register itself in the system. It if does, verify that it is not being monitored using Control Printer Monitoring.command.

On Linux

PaperCut MF tracks printing by integrating with the Common UNIX Printing System (CUPS), the printing system on Linux. For a printer to be tracked, CUPS needs to be told to route print jobs through PaperCut MF before printing.

To do this, the printers.conf file must be edited. This can either be done manually, or assisted via the configure-cups script.

To use the script, run the script file at [app-path]/providers/print/linux-*/configure-cups. Read the script's instructions carefully to enable monitoring on the desired printers.

To edit the file manually:

Open your printers.conf in a text editor such as vim. On most Linux distributions printers.conf is located at /etc/cups/printers.conf.
Prepend papercut: to the DeviceURI of the printers you want to track. After the modification a DeviceURI line might look like:
DeviceURI papercut:ipp://1.2.3.4/printers/My_Printer
Restart CUPS in the way appropriate to your distribution. E.g.:
/etc/init.d/cupsys restart
Perform a test print on each printer. This causes the printers to be registered. This step is not required with the configure-cups script, because the script registers the printers automatically.
The printers should now be registered. Log in to PaperCut MF as admin and verify that the printers are now listed on the Printer List page. Verify that the test prints sent previously were tracked correctly.
