+To print from the command-line, you can use the ''lpr'' command.  **Do not try to print PDF files or images this way.**  The syntax of the print command is
+  lpr -P<printername> filename
+For example:
   lpr -Pcslab test.py
+The printer name is ''cslab'' when you're in P405 or ''advlab'' if you're in P413.
+The command ''lpr'' means to print the file. The option 'P' says which printer to use (one of the CS lab printers), and the argument says which file to print--in this case ''test.py''.
+===== Creating Printable Files =====
+To create a condensed, printable file of your lab, use the ''printLab.sh'' command.
+The syntax of the command is
+  printLab.sh <path_to_lab_directory>
+For example, if you're in your ''labs'' directory, to print lab1, you'd write
+  printLab.sh lab1
+===== Changing Your Password =====
+To change your password, use the ''passwd'' command.
+An example run will look something like:
+  > passwd
+  Changing password for username.
+  Old Password:
+  New Password:
+  Retype new password:
+  passwd: all authentication tokens updated successfully.
+Note that what you type for the passwords does not show up on the screen for your security.
