Congratulations on your RL4 printer purchase. The RL4 printer 
family, hereafter referred to as ‘the printer’, blends the rugged 
durability with state-of-the-art electronics and user-friendly 
features to redefine the standard in portable thermal printers. The 
printer’s RS-232 serial, USB, or optional wireless LAN or Bluetooth
®
 
connectivity allows easy interfacing to any host system. 
 
This manual provides all the information necessary to operate the 
printer.  
 
To print labels or receipts, simply refer to the instructions included 
with the software you have chosen to create the labels.  A 
Windows
®
 printer driver can be found on our website (www.datamax-oneil.com). If you wish to write a 
custom program, a copy of the Programmer’s Manual can also be found on our website.
