Level One Printer Servers
Using BOOTP
If using bootp, no arp table entry is necessary, but the following configuration is required:
1.
Add the following entry to the Boot Table
/etc/bootptab
NAME
:ht=ether:vm=rfc1024::ha=
PA
:ip=
IP
:sm=
SM
:gw=
GW
Where
NAME
is the LevelOne Printer Server’s name
PA
is the hardware address of the LevelOne Printer Server
IP
is the LevelOne Printer Server’s IP Address
SM
is the Subnet Mask
GW
is the Gateway IP Address
2.
If it is not running, start the bootp daemon (the usual command is
bootpd
) and reset
the LevelOne Printer Server. It will then acquire an IP Address using bootp.
Using RARP
If using rarp, no arp table entry is necessary, but the following configuration is required:
1.
If the rarp daemon is not running, start it with the command:
rarpd -a
2.
Add a line to the Ethernet Address table /etc/ethers
00:c0:02:xx:yy:zz NAME
Where
00:c0:02:xx:yy:zz
is the hardware address of the LevelOne Printer Server
NAME
is the name of the LevelOne Printer Server.
3.
Reset the LevelOne Printer Server. When it reboots, it should acquire an IP Address
from rarp.
Printing Methods – Overview
There are 4 printing methods to choose from. All are explained in the following sections.
Select whichever is the most convenient in your environment.
LPD
LPD is a standard print method for most UNIX systems. Using this method eliminates the
need to install additional host softwaret. However, in many cases the LPD protocol sends
out the data file before the control file. The LevelOne Printer Server will print the data file
immediately, ignoring any print options set in the control file. To solve this problem, use
PSfilter instead.
Direct Socket Interface
The Direct Socket Interface (DSI) is a Unix-based method of providing a “direct”
connection between a host computer and a printer. The host and the LevelOne Printer
Server establish a TCP connection, using a special socket number. All data sent over this
connection is treated as print data, and sent transparently to a logical printer defined on the
LevelOne Printer Server.
PSfilter
Psfilter is a proprietary print method provided with the LevelOne Printer Server as “C”
source code.
The benefit of this method is that it provides many print options such as
banner print, copies, and so on. For details, see page 51.
