Introduction

As of May 2018, all CNF printers are printed to via Net-Print.

 CNF is migrating printers to the Net-Print service offered by Cornell Information Technologies.

Net-Print new features include: printing from user owned laptops via Cornell wireless, printing from user owned tablets and phones (coming soon to Net-Print), and tracking of print jobs for users and for CNF Computing staff.

Printing to CNF printers via Net-Print is provided at no cost to CNF users. Other Net-Print printers on campus may incur a cost and first require adding money to one's Net-Print account.

On the backend, Net-Print uses the PaperCut software solution.

Manage Your Net-Print Account

On the Net-Print Account Management web site, one can:

  • view a summary of print jobs and pages
  • view the status of print jobs
  • add money to one's account for non-CNF printers
  • view printer status

When you login to the Net-Print Account Management website, login with the short version of your Cornell NetID or Cornell GuestID. And, of course, your password.

Installing Net-Print/PaperCut Software and Printers

Windows

Use these instructions for your personal Windows computer or on CNF Windows computers if the printer does not automagically appear in the list of printers.

Printing from Windows does not require installation of the PaperCut software on your personal computer.

  1. On your desktop, double-click  My Computer  or run  File Explorer  (Windows 8 or 10) or  Windows Explorer  (Windows 7).
    Please note that we are NOT talking about Microsoft's browser, which is called Internet Explorer.
    1. In the  UNC field  (the wide text field at the top of the window), type in the following Windows UNC for the individual printer, then press  Return  or  Enter  on your keyboard.

      (note that not all printers are available to all users)

  2. Wait a bit.
  3. When prompted, enter your  NetID@cornell.edu  address or your GuestID@cornell.edu address and related password
    Make sure to include the "@cornell.edu" . You can also use: CORNELL\NetID or CORNELL\GuestID (capitalizing "CORNELL").
  4. Make sure Remember my credentials is CHECKED (if you do not check this box, you may get an "Access Denied" error when attempting to print).
  5. Wait a while.
    1. At this point, the varioius pop up dialogues informing of driver installation may go away and nothing else may happen. OR
    2. When the printer status window opens, the printer has been successfully installed. You can close the printer status window.
  6. You can go the list of printers in Windows to confirm the printer is successfully installed.
    1. Windows7: Start Menu → Devices and Printers
    2. Windows10: Start Menu → Settings → Devices → Devices and Printers
  7. Repeat these steps to install any additional printers.

Macintosh

Using PaperCut :

  1. Install Net-Print software for Mac (IT@Cornell web page)
    1. When the installer finishes, a text file will open.  You can safely ignore the information in this text file and move on to step 2 below.
  2. Add Macintosh Print Queues for Net-Print (IT@Cornell web page)
    1. In step 3, for Department, choose RS-CNF .
    2. In step 4, all CNF printers begin with "cnf".
      1. You will see multiple "Find-Me" print queues listed at the top and the specific CNF printers listed at the bottom of the departmental list of printers.

Not Using PaperCut :

  1. System Preferences
    1. Printers & Scanners
    2. Click the "plus" under the list of Printers to add a printer

    14. Select any options included in the Printer
    15. Click "OK"
  2. The printer is successfully added.

Linux

Note that the below instructions are for Linux computers NOT managed by CNF Computing.

  1. Install Samba4 or greater (Samba3 will not work)

    1. RedHat samba4 packages have a bug missing the following symlink, which you must create:

      /usr/lib/cups/backend/smb → /usr/bin/smbspool


      Note that ArchLinux's samba package does not include an smb.conf file by default. Instructions are in the Arch Wiki for obtaining an smb.conf file.

    2. Edit the Samba config file (usually /etc/samba/smb.conf) to contain the following two directives in the "[global]" section:

                client min protocol = SMB2
          client max protocol = SMB3

Without using the PaperCut installers:

Use your Linux distribution's GUI (recommended) or the CUPS gui or the commandline to add a Windows printer

• In RedHat, you can use the Printer configuration tool at System - Administration - Printing

  1. Click New
  2. Enter the administrative password
  3. You do not need to adjust the firewall or attempt to List available devices

  4. For the "device URI", you will use these UNIX SMB URIs :

    Printer NameUNIX SMB URIAccessible by
    Cad Roomsmb://win2.net-print.cornell.edu/cnf-cad-1cCNF Users & Staff
    Toggingsmb://win2.net-print.cornell.edu/cnf-togging-2cCNF Users & Staff
    Visitor Officesmb://win2.net-print.cornell.edu/cnf-gradofficeStaff & Users with Visitor Office Access
    Konicasmb://win2.net-print.cornell.edu/cnf-konica-colorCNF Staff Only
    LJ4700smb://win2.net-print.cornell.edu/cnf-prnt250ljCNF Users during normal CNF office business hours (CNF Staff anytime)
    Office 262smb://win2.net-print.cornell.edu/cnf-prnt262CNF Staff Only
  5. If a driver is not found, you will have to download a driver via the printer gui or separately from the manufacturer's website.

 

• Other Linux distributions may have their own GUIs. You can also use the CUPS gui, if enabled, at

        http://localhost:631

 

  1. Use the above UNIX SMB URIs
  2. Enable authentication for the print queue

    1. If you cannot enable authentication via the CUPS web gui, edit file /etc/cups/printers.conf to add a line for the NetPrint queue:

      AuthInfoRequired username,password

• Using the commandline

  1. Download a PPD for the model of printer
  2. Get the SMB URI for the printer from the section above
  3. As root or sudo'ed, run the following command (substituting in for the brackets)
    lpadmin -p <your_name_for_the_print_queue> -E -P </path/to/PPD-file> -o auth-info-required=username,password -v '<SMB URI>'

Printing via Net-Print/PaperCut

CNF Managed Windows

In the Print dialogue, select the Net-Print printer.

The PaperCut software will prompt you for your username and password.

  1. For your username, use your <NetID>@cornell.edu or your <GuestID>@cornell.edu . The "@cornell.edu" is all lowercase.

Your document prints.

Other Windows

When you are ready to print, choose the Print command in your application and then select a Net-Print printer.

If prompted to login, enter your  NetID@cornell.edu  address or your GuestID@cornell.edu address and related password
Make sure to include the "@cornell.edu" . You can also use: CORNELL\NetID or CORNELL\GuestID (capitalizing "CORNELL").

Macintosh

Follow the instructions on the "Print with Net-Print for Mac" IT@Cornell page.

If prompted for your username when printing, format your NetID/GuestID as follows: cornell\<GuestID> OR cornell\<NetID>

  • That's the lowercase word "cornell" followed by a backslash followed by your NetID or GuestID.

Linux/CNF Thin

In the Print dialogue, select the Net-Print printer.

  1. The "Status" area may say "Unable to connect to CIFS host after (tried 3 times)". This is OK. You will be prompted to connect with your NetID/GuestID credentials in the next step.
