74 AXIS 540+/AXIS 560
Print Methods on TCP/IP Networks
The AXIS 540+/AXIS 560 supports several different print methods in the TCP/IP
environment. axinstall will suggest a print method suitable for your particular
UNIX/Linux system, but you might want to use another method depending on
your printing requirements (banner pages, status logging, etc).
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 540+/AXIS 560 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.
