Common Printing Problems

Please read this PDF about some of the common issues that arise when printing in the Library.

Printing to the Library's Laptop Room Printers 

To print to the Laptop Room's printers, the HP LaserJet 4350tn printer and the Pharos software must be installed on your laptop.  You must be connected to the "hopkins" wireless network (instructions here). Note that laptop printing will not work with the "JHGuestnet" wireless network.

Windows XP/Vista     Mac OS X

For Windows XP or Vista, please perform the following steps:

First, you must add the following WINS IP address to your Wireless Card's network settings:   128.220.183.25

To do this, go to the Control Panel on your system and select "Network Connections" (if you use Windows XP) or "Network and Sharing Center" and then "Manage Network Connections" (if you use Windows Vista).  Right-click the Wireless Connection and select "Properties."  Select the TCP/IP (TCP/IPv4) properties option and then find the WINS addresses page (for Windows XP and Vista, you will need to click the "Advanced" button to get to the WINS addresses page).  Add in the above IP address as a WINS address.  Then, follow the instructions listed below.

1. Download the "hostsedit" application from here and save it onto your laptop.  Do not run this program; you simply need to download it and save it. 
2. You must then download and run the "SAIS_Library_Laptop" batch file to add an entry into one of your system's files (the hosts file).  This file must be saved in the same location as the "hostsedit" file in step # 1.  Download the file from here and then run it (either by opening it when it finishes downloading or by double-clicking on it).  You will see an installation window flash quickly.  Continue with the steps listed below.

To install the double-sided printer, Printer F

To install the single-sided printer, Printer E

1. To install the single-sided HP LaserJet 4350tn printer (printer E) and the Pharos software, download the installation program by clicking here.  Make sure to select the option to "Save this file to disk."
2. After the file has been saved to your system, find it and double-click it.  Click "Install" to start the installation process.
3. When finished, click "Finish" to exit the installation window.  The printer should now be installed on your system.  The printer name will be "SAIS-Lib-2 on SYSTEMS."  Do not change the name of this printer.

 For Macintosh OS X, please perform the following steps:

1. To install the Pharos software, download the installation program by clicking here.
2. After the file has been saved to your system, double-click it to run the Pharos installation program. You will be requested to authenticate yourself as an administrator.
3. Select a destination disk. You will only be able to select the startup disk.
4. Click <Install>. The installer automatically installs Popup 8.0 and required support files.  Continue with the steps listed below.
