1.4 ... about the Printing Methods and Installation Procedures Depending on the selected printing method, the print server can be integrated into various UNIX systems. The printing methods vary depending on the UNIX system version used. The two most commonly used printing methods are remote printing via the LPD protocol and direct printing via TCP/IP ports. Printing via shell scripts is also possible. The following sections give a short overview.
Printing via the Several UNIX systems support the linkage of network printers via the LPD Protocol LPD protocol. In this case, the print server must be installed as a remote printer in the spooler. The user host transfers the print data to the printer by means of the print server.
Printing via Some UNIX systems support the linkage of network printers by TCP/IP Ports means of direct TCP/IP connection. Print data can be transferred from the spooler to the print server via TCP/IP ports.
Printing via When printing via shell scripts, a printer, which the UNIX spooler Shell Scripts considers to be local, is installed. The printer is then entered into the UNIX spooler system. The shell scripts route the print data to the print server by means of FTP.
Which Spoolers Are The print server supports the 'lpsched' (System V), 'lpd' (BSD), and Supported? 'qdaemon' (AIX) spoolers. Search your UNIX system for an available spooler. If your system has the '/usr/lib/lpsched' file, you have System V. If your system has the '/ usr/lib/lpd' and '/etc/printcap' files, you have BSD.
Printing Without a You can send print data directly to the print server by means of FTP Spooler while bypassing the spooler. This method of network printing is used for testing the print server after installation.
Printing in AS/400 The print servers fully support the SCS data stream of the IBM AS/400/iSeries. For IPDS data, only the conversion of fonts is possible. Other IPDS features still have to be converted using special data stream converters that are switched between the print server
Print Server Installation Manual 10 Information
and the printer. In AS/400 there are two ways to operate network printers: • using a remote printer queue (RMTPRTQ) • using a device description In both cases the print-out is carried out via the AS/400/iSeries spool output system.

Print Server Installation Manual 11 Information
1.5 ... about the Assignment of the IP Address to the Host Name As a rule, hosts can be addressed at the user command level ('ping,' 'ftp,' and 'tftp,' for example), with their host names, or directly with their IP addresses. The host name is most commonly used. The host name should be assigned to the IP address. This is carried out either in the local 'etc/hosts' file or on a DNS server. The following section will describe the assignment of the host name to the IP address using the 'hosts' file.
Assignment Files The assignment of the host names to the IP addresses and the IP addresses to the hardware addresses is saved in the following files:
File Assignment
/etc/hosts Assignment of host names to IP addresses
/etc/bootptab Assignment of IP addresses to hardware addresses if the BOOTP boot protocol is used
The '/etc/hosts' file exists on every computer in the network, whereas the other files usually only exist if the listed network services are implemented. Depending on the UNIX system used, the files may also be located in different directories.
The computer from which this installation is carried out must be in the same (sub)network as the print server. Later, the printer may be located anywhere in the network.
Proceed as follows: 1. Log on as root. 2. Add the following entry into the '/etc/hosts' file: Syntax:
Print Server Installation Manual 12 Information
1.6 ... about the Saving of the IP Address in the Print Server TCP/IP network protocols require the storing of the IP address in the print server so that the device can be addressed within the network.
Why IP Addresses? An IP address is used to address network devices in an IP network. Depending on the network type the print server can also be addressed via alternative parameters such as the host name, the print server name, or the IPX address.
How Does the Print SEH print servers are shipped without an IP address. The print server Server Obtain IP is able to assign itself an IP address during the initial installation. Addresses? Boot protocols are used to assign an IP address automatically to the print server. Upon delivery, the boot protocols 'BOOTP', 'DHCP', and 'ZeroConf' are enabled. Once the print server is connected to the network, it checks whether an IP address can be obtained from the boot protocols BOOTP or DHCP. If this is not the case, the print server assigns itself an IP address via ZeroConf from the address range 169.254.0.0/16, which is reserved for ZeroConf. The following methods for saving an IP address in the print server are described in this document: • ’Saving the IP Address via BOOTP’ Ö13 • ’Saving the IP Address Using the 'arp' and 'ping' Commands’ Ö15 • ’Saving the IP Address via the IP Wizard (InterCon-NetTool)’ Ö16
Additional methods for the assignment of IP addresses are described in the print server user manual.
Saving the IP Address via BOOTP If the BOOTP boot protocol has been installed in your network, you must edit the '/etc/bootptab' file.
Print Server Installation Manual 13 Information
Please note that periods separate the address groups of the hardware addresses in this file, whereas colons separate fields from each other in an individual entry. In ULTRIX and some other UNIX systems, the individual fields of an entry are separated from each other using the tab character.
Proceed as follows: 1. Add the following entry to the '/etc/bootptab' file: Syntax for Ethernet:
Proceed as follows: Procedure for 1. Add the following entry to the '/etc/bootptab' file: ULTRIX Syntax for Ethernet:
Print Server Installation Manual 14 Information
Saving the IP Address Using the 'arp' and 'ping' Commands If boot protocols are not implemented in your system, you can use the 'arp' and 'ping' commands to save the IP address. The 'arp' command is used for editing the ARP table. The 'ping' command transfers a data packet containing the IP address to the hardware address of the print server. If the data packet has been successfully sent and received, the print server permanently saves the IP address. Proceed as follows: 1. Edit the ARP table: Ethernet: arp -s
Print Server Installation Manual 15 Information
Saving the IP Address via the IP Wizard (InterCon-NetTool) You can easily enter the desired IP address and save it in the print server using the IP Wizard of the InterCon-NetTool. The IP Wizard helps you to configure the TCP/IP parameters, e.g. the IP address.
Requirements ; The InterCon-NetTool is installed on the client. ; By means of the InterCon-NetTool you can scan the network via Multicast, see: Print Server User Manual. ; The router in the network forwards multicast requests.
Proceed as follows: 1. Start the InterCon-NetTool. 2. Select the print server from the print server list. The print server is displayed in the print server list under 'ZeroConf' with an IP address from the address range 169.254.0.0/16, which is reserved for ZeroConf. 3. Select Installation – IP Wizard from the menu bar. The IP Wizard is started. 4. Follow the instructions of the Wizard. ª The settings are saved.

Print Server Installation Manual 30 Printing via Shell Scripts
4 Printing via Shell Scripts
This chapter describes the installation of your print server for printing via shell scripts in different UNIX systems.
When printing via shell scripts, a printer, which the UNIX spooler considers to be local, is installed. The printer is then entered into the UNIX spooler system. The shell scripts route the print data to the print server by means of FTP. The *.sh shell scripts are sample scripts for the default printer interfaces of the 'lpsched,' 'lpd,' and 'qdaemon' spoolers supported by the print server.
You should only print via shell scripts if you are not able to print by means of LPD protocols or direct TCP/IP ports.
The following shell scripts are available: • aix.sh (for AIX systems with 'qdaemon' spooler) • bsd.sh (for BSD systems with 'lpd' spooler) • sys5.sh (for System V with 'lpsched' spooler) Before you can print via shell scripts, you must first transfer the scripts from the print server and then adapt them to the respective UNIX network. For more detailed information; see: ’Functions and Variables of the Shell Scripts’ Ö44.
The following instructions describe the most fundamental procedures for the corresponding shell scripts. Some commands may vary depending on the UNIX system. For more information, please read the description in your UNIX documentation.
Print Server Installation Manual 31 Printing via Shell Scripts
Requirements ; The print server is known to the network via its IP address, see: Ö13. ; The host name has been assigned to the IP address, see: Ö12. ; The print server is connected and the printer is turned on.
Procedure Follow the instructions to carry out the installation: Creating the Print Server Directories Integrating Shell Scripts into System V Systems Integrating Shell Scripts into BSD Systems Integrating Shell Scripts into AIX Systems
4.1 Creating the Print Server Directories All files that the print server specifically requires should be placed in the '/etc/printserver' directory. In order to print via shell scripts, the shell scripts must be transferred from the print server to the '/etc/printserver' directory via FTP. Proceed as follows: 1. Log on as 'root'. 2. Create the '/etc/printserver/interfaces' directories: - cd /etc - mkdir printserver - cdprintserver - mkdir interfaces 3. Open an FTP connection to the print server: Syntax: ftp
Print Server Installation Manual 32 Printing via Shell Scripts
4.2 Integrating Shell Scripts into System V Systems If the shell scripts are located in the '/etc/printserver' directory, you must adapt them and integrate them into the spooler.
What entries are The following entries are required for the installation: necessary? User input Example in the text
Name of the adapted shell script my_script
Name of the zero device my_device
Name of the printer (visible to the printer after installation) my_printer All three names may be assigned arbitrarily. You may also use one name for all three entries. Every name assigned, however, must be used continuously throughout the installation sequence.
Procedure Follow the instructions to carry out the installation: ’Adapting the Shell Scripts’ Ö33 ’Creating the Printer Device’ Ö34 ’Entering the Printer into the Spooler System’ Ö35 ’Releasing the Printer’ Ö36
Adapting the Shell Scripts The shell script must be adapted to your network. A copy of the shell script is therefore created and saved in the '/etc/printserver/interfaces' directory. After that, the shell script is adapted to your system. This means that the host name of the print server, the logical printer, and the FTP path must be edited.
With print servers with several physical printer ports, the logical printer is used to address the port. For more information, please read the section 'Logical Printers' in the user manual.

Proceed as follows: 1. Copy the '/etc/printserver/sys5.sh' file into the '/etc/printserver/interfaces' subdirectory and assign the copy an arbitrary name: Syntax: cd /etc/printserver cp sys5.sh interfaces/
Creating the Printer Device The print spooler requires a printer device. Due to the fact that the print server does not need a physical device, a link is made to a zero device. Proceed as follows: 1. Enter the following command: Syntax: ln -f /dev/null /dev/
Print Server Installation Manual 34 Printing via Shell Scripts
Entering the Printer into the Spooler System In order to enter the printer into the spooler system, the print spooler must be stopped. The new printer, the zero device, and the shell script are then entered, and the print spooler is restarted. Certain UNIX implementations allow a new printer to be entered without stopping the print spooler. For more information, please read the description in your UNIX documentation. The spooler is administered using the 'lpadmin' command. You may have to enter the complete path ('/usr/lib/lpadmin,' for example) if the 'lpadmin' command is used. • The -F beginning option determines that the print jobs are restarted whenever an error occurs. • The -o nobanner option allows you to deactivate the banner page during print job transmission.
These options are not available in all 'lpadmin' command implementations. These commands are not available for HP-UX and BULL OS, for example. Please note that no space is allowed between a flag and its value.
Proceed as follows: 1. Enter the following command: Syntax: lpshut lpadmin -p
