D - [in lprNG, "timestamp" of when the job was submitted] - * ! E - "environment variables" to set [some versions of linux] - * H - "host name" of machine where the original 'lpr' was done - * I - "indent", the amount to indent output - * J - "job name" to display on banner page - * L - "literal" user's name as it should be displayed on the - * banner page (it is the existence of an 'L' line which - * indicates that a job should have a banner page). - * M - "mail", userid to mail to when done printing (with email - * going to 'M'@'H', so to speak). - * P - "person", the user's login name (e.g. for accounting) - * ! Q - [used by lprNG for queue-name] - * R - "resolution" in dpi, for some laser printer queues - * T - "title" for files sent thru 'pr' - * W - "width" to use for printing plain-text files - * Z - In BSD, "locale" to use for datafiles sent thru 'pr'. - * (this BSD usage should move to a different id...) - * [in lprNG - this line holds the "Z options"] - * 1 - "R font file" for files sent thru troff - * 2 - "I font file" for files sent thru troff - * 3 - "B font file" for files sent thru troff - * 4 - "S font file" for files sent thru troff - * - * The following are attributes attached to a datafile, and thus may - * appear multiple times in a control file (once per datafile): - * - * N - "name" of file (for display purposes, used by 'lpq') - * S - "stat() info" used for symbolic link ('lpr -s') - * security checks. - * - * The following indicate actions to take on a given datafile. The same - * datafile may appear on more than one "print this file" command in the - * control file. Note that ALL ids with lowercase letters are expected - * to be actions to "print this file": - * - * c - "file name", cifplot file to print. This action appears - * when the user has requested 'lpr -c'. - * d - "file name", dvi file to print, user requested 'lpr -d' - * f - "file name", a plain-text file to print = "standard" - * g - "file name", plot(1G) file to print, ie 'lpr -g' - * l - "file name", text file with control chars which should - * be printed literally, ie 'lpr -l' (note: some printers - * take this id as a request to print a postscript file, - * and because of *that* some OS's use 'l' to indicate - * that a datafile is a postscript file) - * n - "file name", ditroff(1) file to print, ie 'lpr -n' - * o - "file name", a postscript file to print. This id is - * described in the original RFC, but not much has been - * done with it. This 'lpr' does not generate control - * lines with 'o'-actions, but lpd's printjob processing - * will treat it the same as 'l'. - * p - "file name", text file to print with pr(1), ie 'lpr -p' - * t - "file name", troff(1) file to print, ie 'lpr -t' - * v - "file name", plain raster file to print - * - * U - "file name" of datafile to unlink (ie, remove file - * from spool directory.
