Epson Color Laser Printer Owner's Manual page 152

Public Access Printers:
NDPS printers that are available to all network users and not
associated with an NDS object. Users can select and print to
any public access printer they can view from their
workstations. However, these printers do not take full
advantage of services such as security and job event
notification.
Controlled Access Printers:
NDPS printers that are added to the NDS tree by NetWare
Administrator. They are only available to the workstation
user through the NDS object list. These printers can take full
advantage of the security and management features provided
by NDS.
Note on using the Adobe PostScript 3 Kit:
If you want to use a printer as a PostScript and ESC/Page printer and
want to install the printer driver automatically to the client computer,
you must create two Printer Agents: one for the PostScript printer driver
and the other for the ESC/Page printer driver. If you create one with
Remote (rprinter on IPX), create the other with Remote (LPR on IP).
You can create two Printer Agents with the LPR protocol (called LPR
Printer Agent), but cannot create two Printer Agents with the IPX
protocol (called IPX Printer Agent) for the same printer.
Creating a Printer Agent automatically
You can create a Printer Agent automatically. Only public access
printers can be created in this way. See "Creating Public Access
Printers Automatically" in the EpsonNet NDPS Gateway manual
for detailed information.
