Print Methods on TCP/IP Networks

The AXIS 540/640 supports several different print methods in the TCP/IP environment. axinstall will suggest a print method suitable for your particular UNIX 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 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 print methods

LPD The Line Printer Daemon is a protocol for transferring print jobs between hosts. This is the recommended method for UNIX systems, but some System V versions do not support LPD.

Advantages:

Easy to set up – install the AXIS 540/640 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.
