475 Printer Connected to a G3 
Management Terminal
The 475 printer can b e c onnected to a G3 Management Terminal to provide hard 
copies of administration data. It can also be used as an output receiving device 
for station message detail recording. In each case, the printer option switch 
settings are the same. Table H-17 shows the o ption switch settings for the 475 
printer when it is used in these applications. 
475 Printer Used as System Printer
The 475 printer can be connected to the DEFINITY  System G3 as the system 
printer to be used by the Report Scheduler. Table H-18 shows the option switch 
settings for the 475 printer as a system printer. 
475 or 476 Printer Used as Journal
Printer for Hospitality Feature
The 475 or 476 printer can also be used as a journal printer to support the 
hospitality feature. Table H-19 shows the option switch settings for the 475 and 
476 printers in this a p plication.
When modular processor data module or modular trunk data module are used 
with the 475 or 476 journal p rinters, the option switches on the modular 
processor data module or modular trunk data module must  be set as shown 
Table H-20.
