  • Printer options. Choose from a variety of popular printers supported by the PC. Up to three printers are supported at any one time, each running independently while another host or PC application is active.

  • Hotspots identify host menu items. Host menu items and function keys can be assigned colors. Employ this aesthetic and intuitive approach to locate them quickly and easily.

  • Keystroke memory and playback (macros). Predefine keystrokes for automated sign-on, repetitive data entry, or unattended operation. Store as many as 2,048 keystrokes in up to 24 keyboard macros.
