Applications are located in various specific directories in the network file system. Most large applications consist of many smaller programs and data files. To start an application, you have to type the name of the executable. The path of the application must be located in the .xinitrc file. The path is simply the directory where the executable is located.
Most user accounts have their .xinitrc files pre-configured.
Whenever you print a file, it is sent into the print queue. Make sure you know where the file you want to print is located. You will not get a confirmation that indicates that your file has been inserted into the print queue. Type lpq to find out whether the file is indeed on the print queue. If it is not, the machine you are working on may not be able to connect to the print server.
