AXIS 5400+ / AXIS 5600+ User’s Manual
Print Methods on TCP/IP Networks
The AXIS 5400+/AXIS 5600+ supports several different print methods in
the TCP/IP environment. Depending on your printing requirements
(banner pages, status logging, etc), seelct a print method suitable for your
particular UNIX/Linux system.
The diagram below shows the alternative data paths taken by some of the
UNIX/Linux print methods. This illustrates some of the advantages and
limitations of the different methods. Use the following information to
determine which method to adopt.
Illustration of different UNIX/Linux print methods
LPD
The Line Printer Daemon is a protocol for transferring print jobs between
hosts. This is the recommended method for UNIX/Linux systems, but
some System V versions do not support LPD.
Advantages:
Easy to set up — install the AXIS 5400+/AXIS 5600+ as a remote queue in
System V, or add a remote printer to
/etc/printcap
using the
rm
and
rp
fields (BSD).
Limitations:
Spooler features, and
printcap
or
lpr
options (BSD) such as multiple
copies, are not available.
FTP
The File Transfer Protocol is used for transferring files between hosts.
Advantages:
Uses industry standard network software on the host.
Limitations:
No printer status logging. In the case of
BSD it may
conflict with other
input or output filters and does not allow both input and output filters. In
System V
no filters or interface programs can be used.
