/**
 * Demonstrasi cara mencetak struk dengan printer dot matrix.
 *
 * Pada contoh kode berikut, kita mencetak langsung ke device printer,
 * tidak melalui print service Operating System (print dialog).
 *
 * Sebelum menjalankan contoh kode berikut,
 * pastikan Anda bisa mencetak langsung melalui command prompt.
 *
 * Contoh : di linux menggunakan printer paralel
 * <pre><code>
 * echo "Hello World" > /dev/lp0
 * </code></pre>
 *
 * Bila Anda mendapatkan pesan error, biasanya karena hal berikut :
 * <ul>
 * <li>Salah menggunakan nama device. <br />
 * Pastikan device /dev/lp0 adalah nama device yang benar.<br />
 * Biasanya terjadi kesalahan di sini bila menggunakan printer USB.
 * </li>
 * <li>Permission user tidak memadai. <br />
 * Setelah memastikan Anda menggunakan device yang benar,
 * periksa permissionnya. <br />
 * Di instalasi Ubuntu standar, /dev/lp0 memiliki permission 660
 * dengan owner root dan group lp. <br />
 * Pastikan user yang digunakan adalah root,
 * atau user biasa yang tergabung ke dalam grup lp
 * </li>
 * </ul>
