AXIS 5900 User’s Manual

Print Methods on TCP/IP Networks

The AXIS 5900 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 5900 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.
