uses a spooling daemon to print the named files when facilities become available. If no names appear, the standard input is assumed. The following single letter options are used to notify the line printer spooler that the files are not standard text files. The spooling daemon will use the appropriate filters to print the data accordingly. The files are assumed to contain data produced by The files are assumed to contain data from for- mat from Stanford). Use a filter which interprets the first character of each line as a standard carriage control character. The files are assumed to contain standard plot data as produced by the routines (see also for the filters used by the printer spooler). Use a filter which allows control characters to be printed and suppresses page breaks. The files are assumed to contain data from (device independent troff). Use to format the files (equivalent to The files are assumed to contain data from (cat phototypesetter commands). The files are assumed to contain a raster image for devices like the Benson Varian. These options apply to the handling of the print job: Force output to a spe- cific printer. Normally, the default printer is used (site dependent), or the value of the environment variable is used. Suppress the printing of the burst page. Send mail upon comple- tion. Remove the file upon completion of spooling. Can not be used with the option, due to security concerns. Use symbolic links. Usually files are copied to the spool directory. The option will use to link data files rather than trying to copy them so large files can be printed. This means the files should not be modified or removed until they have been printed. The remaining options apply to copies, the page display, and headers: The quantity is the number of copies desired of each file named. For example, lpr -#3 foo.c bar.c more.c would result in 3 copies of the file foo.c, followed by 3 copies of the file bar.c, etc. On the other hand, cat foo.c bar.c more.c | lpr -#3 will give three copies of the concatenation of the files. Often a site will disable this feature to encourage use of a photocopier instead. Specifies a to be mounted on font position The daemon will con- struct a file referencing the font pathname. Job classification to use on the burst page. For example, lpr -C EECS foo.c causes the system name (the name returned by to be replaced on the burst page by and the file foo.c to be printed. Job name to print on the burst page. Normally, the first file's name is used. Title name for instead of the file name. User name to print on the burst page, also for accounting purposes. This option is only honored if the real user-id is daemon (or that specified in the printcap file instead of daemon), and is intended for those instances where print filters wish to requeue jobs. The output is indented. If the next argument is numeric it is used as the number of blanks to be printed before each line; otherwise, 8 characters are printed. Uses as the page width for If the fol- lowing environment variable exists, it is used by Specifies an alternate default printer. Personal identification. Printer capabilities data base. Line printer daemons. Directories used for spooling. Daemon control files. Data files specified in "cf" files. Temporary copies of "cf" files. The command appeared in If you try to spool too large a file, it will be truncated. will object to printing binary files. If a user other than root prints a file and spooling is disabled, will print a message saying so and will not put jobs in the queue. If a connection to on the local machine cannot be made, will say that the daemon cannot be started. Diagnostics may be printed in the daemon's log file regarding missing spool files by Fonts for and reside on the host with the printer. It is currently not pos- sible to use local font libraries. 1
