Print Methods on TCP/IP Networks
The AXIS 5500/AXIS 5550 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.

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 5500/AXIS 5550 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.
