About CTA


Please note:

Large amounts of work can be done without printing. Try and avoid unnecessary printing to save on paper wastage, toners, drums and even entire printers.
Often printing to PDF and storing that file on your team drive is more effective.

Please ask your local computing support to discuss options further

If you wish to print out a large document that has some colour pages but the majority are monochrome, then it is cheaper (and quicker) for you to selectively print the colour pages to the colour printer and the black and white pages to the photocopier.
You will need to sort the pages out by hand afterwards, but this often will take less time the waiting for the slower colour printer to finish.

These pages provide you with information on how to use the library printer. Word of warning, we support the printer and server not your workstation. We will ensure that the server is functioning across the network, however you will need to talk to you local computer officer for direct client assistance.

Connecting to the printer (Windows)

From your Desktop

  1. Click on Start
  2. Click on Run...
  3. Type \\prn3.cta.phy.private.cam.ac.uk /USER:*type username here*
  4. Click OK... (A window will pop up with the printers available)

  5. Double click on "HPLJ4600LIB"
  6. If you are prompted to install a printer driver, click "Yes".

Once the printer installation has finished you should now be able to print.

Connecting to the printer (Linux)

SMB and CIFS are the Windows file and printer sharing protocols. We use Samba to speak to the Windows PCs using these protocols. Before configuring CUPS we should make sure we can connect to the Windows PC with smbclient, the Samba SMB/CIFS client Figure 2.

The following is an example of creating a connection to a Windows PC:

%user%@machine:~> smbclient -L prn3 -N

Anonymous login successful

Sharename   Type    Comment
print$      Disk    Printer Drivers
HPJL4600LIB Printer HPLJ4600LIB
IPC$        IPC     Remote IPC 
The command shown asks for a list of shares on a Windows PC named "PRN3", with no password given. The results show a printer named "PS1". If Windows naming service is unavailable you will need to specify the IP address of the Windows PC with the -I switch as in:
%user%@machine:~> smbclient -I -L prn3 -N
For more information see the Samba documentation about smbclient usage. Once you have found a Windows printer you may configure CUPS. First verify that your installation of CUPS has the smb backend with the following command:
%user%@machine:~> ls -l /usr/lib/cups/backend/smb
If this file does not exist create it by issuing the following:
%user%@machine:~> ln -s `which smbspool` /usr/lib/cups/backend/smb
The following is an example of setting up the printer shown above:
lpadmin -p Prn3HPLJ4600LIB -v smb://prn3/PS1 -P /root/$printer.ppd
enable Prn3HPLJ4600LIB
accept Prn3HPLJ4600LIB
lpadmin -d Prn3HPLJ4600LIB
If Windows naming service is unavailable, add the switch -h followed by the IP address of the Windows PC to the first lpadmin command as in:
lpadmin -p Prn3HPLJ4600LIB -h -i smb://prn3/HPLJ4600LIB /root/$printer.ppd
Your printer is now ready to test. Send a file to the printer with the lp command followed by a filename, or by printing a document from within an application.

Printing under MacOS

If you know how to do it, please let us know as I don't have the hardware here to do test it. Thanks!
