The spooling system accesses the .Nm printcap file every time it is used, allowing dynamic addition and deletion of printers. Each entry in the data base is used to describe one printer. This data base may not be substituted for, as is possible for .Xr termcap , because it may allow accounting to be bypassed. .Pp The default printer is normally .Em lp , though the environment variable .Ev PRINTER may be used to override this. Each spooling utility supports an option, .Fl P Ar printer , to allow explicit naming of a destination printer. .Pp Refer to the .%T "4.3 BSD Line Printer Spooler Manual" for a complete discussion on how to setup the database for a given printer. .Sh CAPABILITIES Refer to .Xr termcap 5 for a description of the file layout. .Bl -column Name Type "/var/spool/lpd" .Sy Name Type Default Description .It "af str" Ta Dv NULL Ta No "name of accounting file" .It "br num none if lp is a tty, set the baud rate" .Pf ( Xr ioctl 2 call) .It "cf str" Ta Dv NULL Ta No "cifplot data filter" .It "df str" Ta Dv NULL Ta No "tex data filter" .Pf ( Tn DVI format) .It "fc num 0 if lp is a tty, clear flag bits" .Pq Pa sgtty.h .It "ff str" Ta So Li \ef Sc Ta No "string to send for a form feed" .It "fo bool false print a form feed when device is opened" .It "fs num 0 like `fc' but set bits" .It "gf str" Ta Dv NULL Ta No "graph data filter" .Pf ( Xr plot 3 format .It "hl bool false print the burst header page last" .It "ic bool false driver supports (non standard) ioctl to indent printout" .It "if str" Ta Dv NULL Ta No "name of text filter which does accounting" .It "lf str" Ta Pa /dev/console Ta No "error logging file name" .It "lo str" Ta Pa lock Ta No "name of lock file" .It "lp str" Ta Pa /dev/lp Ta No "device name to open for output" .It "ms str" Ta Dv NULL Ta No "list of terminal modes to set or clear" .It "mx num 1000 maximum file size (in" .Dv BUFSIZ blocks), zero = unlimited .It "nd str" Ta Dv NULL Ta No "next directory for list of queues (unimplemented)" .It "nf str" Ta Dv NULL Ta No "ditroff data filter (device independent troff)" .It "of str" Ta Dv NULL Ta No "name of output filtering program" .It "pc num 200 price per foot or page in hundredths of cents" .It "pl num 66 page length (in lines)" .It "pw num 132 page width (in characters)" .It "px num 0 page width in pixels (horizontal)" .It "py num 0 page length in pixels (vertical)" .It "rf str" Ta Dv NULL Ta No "filter for printing" .Tn FORTRAN style text files .It "rg str" Ta Dv NULL Ta No "restricted group.

The filters selected depend on the flags passed to .Xr lpr 1 . The pipeline set up is: .Bd -literal -offset indent p pr | if regular text + pr(1) none if regular text c cf cifplot d df DVI (tex) g gf plot(3) n nf ditroff f rf Fortran t tf troff v vf raster image .Ed .Pp The .Sy if filter is invoked with arguments: .Bd -filled -offset indent .Cm if .Op Fl c .Fl w Ns Ar width .Fl l Ns Ar length .Fl i Ns Ar indent .Fl n Ar login .Fl h Ar host acct-file .Ed .Pp The .Fl c flag is passed only if the .Fl l flag (pass control characters literally) is specified to .Xr lpr . The .Ar Width function and .Ar length specify the page width and length (from .Cm pw and .Cm pl respectively) in characters. The .Fl n and .Fl h parameters specify the login name and host name of the owner of the job respectively. The .Ar Acct-file function is passed from the .Cm af .Nm printcap entry. .Pp If no .Cm if is specified, .Cm of is used instead, with the distinction that .Cm of is opened only once, while .Cm if is opened for every individual job. Thus, .Cm if is better suited to performing accounting. The .Cm of is only given the .Ar width and .Ar length flags. .Pp All other filters are called as: .Bd -filled -offset indent .Nm filter .Fl x Ns Ar width .Fl y Ns Ar length .Fl n Ar login .Fl h Ar host acct-file .Ed .Pp where .Ar width and .Ar length are represented in pixels, specified by the .Cm px and .Cm py entries respectively. .Pp All filters take .Em stdin as the file, .Em stdout as the printer, may log either to .Em stderr or using .Xr syslog 3 , and must not ignore .Dv SIGINT . .Sh LOGGING Error messages generated by the line printer programs themselves (that is, the .Xr lp Ns * programs) are logged by .Xr syslog 3 using the .Dv LPR facility. Messages printed on .Em stderr of one of the filters are sent to the corresponding .Cm lf file. The filters may, of course, use .Xr syslog themselves. .Pp Error messages sent to the console have a carriage return and a line feed appended to them, rather than just a line feed. .Sh SEE ALSO .Xr termcap 5 , .Xr lpc 8 , .Xr lpd 8 , .Xr pac 8 , .Xr lpr 1 , .Xr lpq 1 , .Xr lprm 1 .Rs .%T "4.3 BSD Line Printer Spooler Manual" .Re .Sh HISTORY The .Nm file format appeared in .Bx 4.2 ..
