Connectivity and network management

Any single print server on any given physical network can accept and process print jobs
from any or all of these logical networks concurrently. For example, if a MarkNet N2000
physically attaches an Optra W810 to an Ethernet network, then a NetWare client, an
AppleTalk user, and an OS/2 Warp client can all send print jobs to the printer simulta-
neously. The print jobs are processed on a first-come, first-served basis.
Input buffers
Each port on the printer has a separate buffer for receiving print jobs. The size of each of
these input buffers is variable, and can be configured to meet specific system needs using
the menus on the printer operator panel, or remotely using MarkVision or PJL commands.
Each of the input buffers is divided into two areas. One area is allocated as the NPA buffer
and receives all NPA commands sent to the printer. The other area is allocated to receive
all other data on the port.
Note:
The factory default for the NPA Mode menu item is Auto. You can, however,
set NPA Mode off for each attachment port. If you disable NPA Mode, all of
the input buffer memory is used to receive normal PostScript or PCL
emulation data.
The default setting for each of the buffer menus is Auto. The printer automatically deter-
mines the size of the input buffer, depending on the specific port and the amount of
installed memory. The following table contains the default buffer sizes for each of the
ports.
