Print filters are programs that convert print requests from one format to another. The LP print service uses filters to perform the following tasks:
Not every print filter can perform all these tasks. Because each task is printer-specific, you can implement each one separately.
Solaris 2.x system software provides a default set of PostScript filters. Some of the TranScript filters used with SunOS 4.x have Solaris 2.x equivalents, and some do not. Table 11-7 lists and describes the default PostScript filters and identifies the TranScript filters, when applicable.
| Filter | Action | TranScript Equivalent |
|---|---|---|
| download | Download fonts | |
| dpost | ditroff to PostScript | psdit |
| postdaisy | daisy to PostScript | |
| postdmd | dmd | |
| postio | Communicate with printer | pscomm |
| postior | Communicate with printer | |
| postmd | Matrix gray scales to PostScript | |
| postplot | plot to PostScript | psplot |
| postprint | simple to PostScript | enscript |
| postreverse | Reverse or select pages | psrev |
| posttek | TEK4014 to PostScript | ps4014 |
Solaris 2.x system software does not provide the following filters:
The universal address is required for setting up both print servers and print clients. As part of configuring the network listen process to listen for print requests from other systems, you must provide the universal address—the IP address of the print server in hexadecimal form—to the LP print service. You use the lpsystem -A command to find the universal address. The universal address has four parts, as shown in Figure 11-1. The last part, RFU, means Reserved for Future Use, and you could use it for other families of addresses (for example, Open Systems Interface) in the future.

You can define a printer description for a printer. The description can contain any helpful information that might benefit its users. For example, the description could say where the printer is located, or whom to call when the printer has problems.
Users can display the printer's description by typing the command:
% lpstat -D -p printer-name
You can specify a default printer for each system, even if it is the only printer connected to the system. When you specify a default printer, users do not need to type the default printer name when they use LP print service commands. However, they can override the default by explicitly naming a printer or setting the LPDEST environment variable. Before you can designate a default printer, it must be known to the LP print service on the system.
The first task in setting up a print server is to set the printer up as a local Solaris 2.x printer. You generally perform the following tasks to set up a local printer:
You need the following information to set up a local printer:
