[. . . ] When configuring the printer, YaST defaults to the one marked recommended as a general rule. To get a list of PPD files available for a printer, select PPD file in Configuration then click Edit. See Figure 20. 1, "Printer Configuration Summary" (page 445). Normally it should not be necessary to change the PPD file--the PPD file chosen by YaST should produce the best results. However, if you want a color printer to print only in black and white, for example, it is most convenient to use a PPD file that does not support color printing. If you experience performance problems with a PostScript printer when printing graphics, it may help to switch from a PostScript PPD file to a PCL PPD file (provided your printer understands PCL). 446 Deployment Guide 20. 4. 2 Configuring Network Printers with YaST Network printers are not detected automatically. Depending on your network setup, you can print to a print server (CUPS, LPD, SMB, or IPX) or directly to a network printer (preferably via TCP). Ask your network administrator for details on configuring a network printer in your environment. Procedure 20. 2 Configuring a Network Printer with YaST 1 Start YaST and choose Hardware > Printer to open the Printer Configuration dialog. 3 Choose Network Printers to open a dialog in which to specify further details that should be provided by your network administrator. 20. 5 Network Printers A network printer can support various protocols, some of them even concurrently. Although most of the supported protocols are standardized, some manufacturers expand (modify) the standard because they test systems that have not implemented the standard correctly or because they want to provide certain functions that are not available in the standard. Manufacturers then provide drivers for only a few operating systems, eliminating difficulties with those systems. The current situation is such that you cannot act on the assumption that every protocol works smoothly in Linux. Therefore, you may have to experiment with various options to achieve a functional configuration. IMPORTANT: Remote Access Settings By default, the cupsd only listens on internal network interfaces (localhost). When setting up a CUPS network server you need to adjust the Listen directive in /etc/cups/cupsd. conf to listen to the outer network. CUPS supports the socket, LPD, IPP, and smb protocols. Printer Operation 447 socket Socket refers to a connection in which the data is sent to an Internet socket without first performing a data handshake. Some of the socket port numbers that are commonly used are 9100 or 35. The device URI (uniform resource identifier) syntax is socket://IP. of. the. printer:port, for example, socket://192. 168. 2. 202:9100/. LPD (Line Printer Daemon) The proven LPD protocol is described in RFC 1179. Under this protocol, some job-related data, such as the ID of the printer queue, is sent before the actual print data is sent. Therefore, a printer queue must be specified when configuring the LPD protocol for the data transmission. [. . . ] As with a normal installation, protocol stands for any of the supported network protocols (NFS, HTTP, FTP, etc. ) and instsource for the path to your network installation source. 2 Boot the system using "Wake on LAN", as described in Section 4. 3. 7, "Wake on LAN" (page 67). Once you have entered the rescue system, you can make use of the virtual consoles that can be reached with Alt + F1 to Alt + F6. Common Problems and Their Solutions 835 A shell and many other useful utilities, such as the mount program, are available in the /bin directory. The sbin directory contains important file and network utilities for reviewing and repairing the file system. [. . . ]
