Adding and configuring an LPD gateway

To configure the LPD gateway, select Settings > Additional Gate-ways > Line Printer Daemon in Expert mode in the Messaging Server Configuration program. In the left-hand dialog field you see all the LPD gateways that are currently present in the Messaging Server system. In the standard system, this is the lpd0 gateway.

If you want to perform an update installation, you must register the LPD gateway manually in the existing configuration even though this gateway has already been installed. If lpd0 is not present, you must first set it up by clicking Create Component in the Component table.

Figure 3.29: Setting up the Component table

You should, for example, call the LPD gateway lpd0. As Host, select the IP address or the resolved name of the server on which the LPD gateway is to run (usually the Main server). Following that, accept the new settings. The system updates the display.

The LPD gateway‘s default settings are suitable for most installations.

You only need to change them in the following cases (sorted by how often they may occur):

1. OfficeMaster 10 or OfficeMaster 25 do not have a PCL converter (modify this parameter: File format).

2. LPD send jobs are not to be processed by the FSRV-Server (FSRV), but by a different gateway, such as the Fax Connector for Exchange (MSX2KGATE), the FAX gateway for Notes (NOTES-CONN), the Mail gateway (MAILGW) or the File gateway (FILEGW) instead. You may need to specify this if you also want OfficeMaster to send commercial documents as e-mails, because the FSRV-Server only supports fax transmissions (modify the Gateway com-ponents parameter).

3. If the LPD gateway is to receive jobs either on a different port, or only to particular IP addresses (modify the relevant parameter: Port, Interface, Edit messages from).

In the last case, you must modify the parameters under the Network settings. In cases 1 to 3, you must either modify the rules input under Printer queue or add new rules.

Network settings

►

The default setting is for the LPD gateway to receive data streams on Port 515 (the Well Known Port). However, if this Port is not available on the server e.g. because of a firewall or another LPD server, you can assign the LPD gateway to a different Port. In this case the applications used to print data with LPD/LPR must also send their data streams to the new Port.

►

In the same way as for port settings, you can specify the IP address as the Interface. The LPD gateway will then wait for inbound data streams on this address. This is especially useful if you are running servers with several network cards and router functions and you want the LPD gate-way to accept data streams from only one specific network segment.

The LPD gateway uses the default setting 0.0.0.0 to connect to each

Interface, or to all IP addresses, and accepts send jobs from all network segments.

►

Under Process messages from you can use regular expressions (see section 9.3) to input a list of IP addresses that are permitted to send data to the LPD gateway. The default setting (.*.*) means the LPD gateway accepts data streams from every IP address.

Printer queues

The printer queue the sender selects for the send job defines how the Messaging Server processes the data streams it receives. By default, every send job is processed in the same way, no matter which printer queue is specified.

►

You can enter a Name for the printer queue, either in plain text or as a regular expression (see section 9.3). In the standard system, send jobs to all the printer queues (.*.*) are processed in the same way. You should only configure the Name if a number of different rules have been entered to specify that jobs are to be processed in different ways by the various different queues.

►

After the LPD gateway has received a send job, it sends it to the gateway component configured for that particular printer queue. The gateway component checks the job („is the sender authorised to send documents?“), sets user-specific send parameters („should the job be signed?“) and, once the job has been sent, ensures that the sender re-ceives a status report. Depending on which type of OfficeMaster license you have, you can, or must, use the following gateway components.

As the File format that is to be received by the LPD gateway and con-verted by the Messaging Server cannot be defined automatically, you must configure it for every individual printer queue rule.

These File formats can be converted by the OfficeMaster Messaging Server:

• PCL (Printer Common Language),

• PDF (Portable Document Format),

• PS (Postscript)

• TXT (ASCII text).

OfficeMaster Messaging Server running in Windows environments has its own converter for converting TXT and PCL files into graphics (for fax) or PDF (for e-mail).

▼

At first glance, using AFPL GhostScript might not appear to be a benefit because of the additional time and effort required to install it. However, its PS conversion function does allow you to create searchable PDF do-cuments (for e-mail!). If you use the PCL converter the printed document is inserted in the PDF file as a bitmap.
