The files that you accumulate and use will vary in their content. Some files will be binary, some text, some postscript, and so on and so forth. Not all file types are printable. All of the School's printers are postscript laser printers. If you send a file to the printer which is not a postscript file, and appears to be a text file, it will be converted into postscript and then printed (more about this in the next section).
Remember that there is a quota on the number of pages you are allowed to print. Your print quota is discussed in section 1.9.5 on page .
