36 .Nd printer capability data base
43 is a simplified version of the
46 used to describe line printers. The spooling system accesses the
48 file every time it is used, allowing dynamic
49 addition and deletion of printers. Each entry in the data base
50 is used to describe one printer. This data base may not be
51 substituted for, as is possible for
53 because it may allow accounting to be bypassed.
55 The default printer is normally
57 though the environment variable
59 may be used to override this. Each spooling utility supports an option,
61 to allow explicit naming of a destination printer.

178 If the local line printer driver supports indentation, the daemon
179 must understand how to invoke it.
183 daemon creates a pipeline of
185 to process files for various printer types.
186 The filters selected depend on the flags passed to
188 The pipeline set up is:
189 .Bd -literal -offset indent
190 p pr | if regular text + pr(1)
203 filter is invoked with arguments:
204 .Bd -ragged -offset indent
211 .Fl h Ar host acct-file
216 flag is passed only if the
218 flag (pass control characters literally)
226 specify the page width and length
231 respectively) in characters.
236 parameters specify the login name and host name of the owner
237 of the job respectively.
251 with the distinction that
256 is opened for every individual job.
259 is better suited to performing accounting.
268 All other filters are called as:
269 .Bd -ragged -offset indent
274 .Fl h Ar host acct-file
281 are represented in pixels,
286 entries respectively.

309 different arguments as above. Specifically, the output filter is

319 is not executed locally, but is requested of the remote
321 Any input filtering via
323 will therefore happen before
325 is executed rather than afterwards.
327 There are some models of network printers which accept jobs from
329 but they ignore the control file for a job and simply print
330 each data file as it arrives at the printer.
331 One side-effect of this behavior is that the printer will ignore any request
332 for multiple copies as given with the
341 to resend each data file for each copy that the user
342 originally requested.

358 .Sh TRANSFER STATISTICS
359 When a print job is transferred to a remote machine (which might be
360 another unix box, or may be a network printer), it may be useful
361 to keep statistics on each transfer. The
365 options indicate filenames that lpd should use to store such
366 statistics. A statistics line is written for each datafile of a
367 job as the file is successfully transferred. The format of the
368 line is the same for both the sending and receiving side of a
371 Statistics on datafiles being received would be used on a print
372 server, if you are interested in network performance between a
373 variety of machines which are sending jobs to that print server.
374 The print server could collect statistics on the speed of each
375 print job as it arrived on the server.
377 Statistics on datafiles being sent might be used as a minimal
378 accounting record, when you want to know who sent which jobs to a
379 remote printer, when they were sent, and how large (in bytes) the
380 files were. This will not give include any idea of how many pages
381 were printed, because there is no standard way to get that information
382 back from a remote (network) printer in this case.
