- DDEESSCCRRIIPPTTIIOONN
- The PPrriinnttccaapp function is a simplified version of the termcap(5) data base
- used to describe line printers. The spooling system accesses the
- pprriinnttccaapp file every time it is used, allowing dynamic addition and dele-
- tion 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
- termcap, because it may allow accounting to be bypassed.
-
- The default printer is normally _l_p, though the environment variable
- PRINTER may be used to override this. Each spooling utility supports an
- option, --PP _p_r_i_n_t_e_r, to allow explicit naming of a destination printer.
-
- Refer to the _4_._3 _B_S_D _L_i_n_e _P_r_i_n_t_e_r _S_p_o_o_l_e_r _M_a_n_u_a_l for a complete discus-
- sion on how to setup the database for a given printer.

- troff)
- of str NULL name of output filtering program

- cents

-
-
- allowed access
- rm str NULL machine name for remote printer
- rp str ``lp'' remote printer name argument
- rs bool false restrict remote users to those with
- local accounts
- rw bool false open the printer device for reading and
- writing
- sb bool false short banner (one line only)
- sc bool false suppress multiple copies
- sd str _/_v_a_r_/_s_p_o_o_l_/_l_p_d spool directory
- sf bool false suppress form feeds

- tr str NULL trailer string to print when queue
- empties
- vf str NULL raster image filter
- xc num 0 if lp is a tty, clear local mode bits
- (tty(4))
- xs num 0 like `xc' but set bits
-
- If the local line printer driver supports indentation, the daemon must
- understand how to invoke it.
-
- FFIILLTTEERRSS
- The lpd(8) daemon creates a pipeline of _f_i_l_t_e_r_s to process files for var-
- ious printer types. The filters selected depend on the flags passed to
- lpr(1). The pipeline set up is:
-
- 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
-
- The iiff filter is invoked with arguments:
-
- iiff [--cc] --ww_w_i_d_t_h --ll_l_e_n_g_t_h --ii_i_n_d_e_n_t --nn _l_o_g_i_n --hh _h_o_s_t _a_c_c_t_-_f_i_l_e
-
- The --cc flag is passed only if the --ll flag (pass control characters liter-
- ally) is specified to lpr. The _W_i_d_t_h function and _l_e_n_g_t_h specify the
- page width and length (from ppww and ppll respectively) in characters. The
- --nn and --hh parameters specify the login name and host name of the owner of
- the job respectively. The _A_c_c_t_-_f_i_l_e function is passed from the aaff
- pprriinnttccaapp entry.
-
- If no iiff is specified, ooff is used instead, with the distinction that ooff
- is opened only once, while iiff is opened for every individual job. Thus,
- iiff is better suited to performing accounting. The ooff is only given the
- _w_i_d_t_h and _l_e_n_g_t_h flags.
-
- All other filters are called as:
-
- ffiilltteerr --xx_w_i_d_t_h --yy_l_e_n_g_t_h --nn _l_o_g_i_n --hh _h_o_s_t _a_c_c_t_-_f_i_l_e
-
- where _w_i_d_t_h and _l_e_n_g_t_h are represented in pixels, specified by the ppxx and
- ppyy entries respectively.
-
- All filters take _s_t_d_i_n as the file, _s_t_d_o_u_t as the printer, may log either
- to _s_t_d_e_r_r or using syslog(3), and must not ignore SIGINT.
-
- LLOOGGGGIINNGG
- Error messages generated by the line printer programs themselves (that
- is, the lp* programs) are logged by syslog(3) using the LPR facility.
- Messages printed on _s_t_d_e_r_r of one of the filters are sent to the corre-
- sponding llff file. The filters may, of course, use syslog themselves.
-
- Error messages sent to the console have a carriage return and a line feed
- appended to them, rather than just a line feed.
