Screen changes to “HSC/Printer 
Module Rebooting”. Press OK. Return 
to Printer programming screen. 
• Enter baud rate for printer: 
0 = 1200, 1 = 2400, 2 = 4800,

•  If CTS is enabled (), only users with 
authority to view History can start the 
printer if it runs out of paper, etc. If it is 
disabled (), simply fixing the printer 
problem (e.g. load paper) will re-start 
the printer. Press Save.
