Each two-letter capability has a human-readable alternate name.
If the local line printer driver supports indentation, the daemon must understand how to invoke it.

filter is invoked with arguments:
If no if is specified, of is used instead, with the distinction that of is opened only once, while if is opened for every individual job. Thus, if is better suited to performing accounting. The of is only given the width and length flags.
All other filters are called as:
where width and length are represented in pixels, specified by the px and py entries respectively.
All filters take stdin as the file, stdout as the printer, may log either to stderr or using syslog(3), and must not ignore SIGINT.
There are some models of network printers which accept jobs from
but they ignore the control file for a job and simply print
each data file as it arrives at the printer.
One side-effect of this behavior is that the printer will ignore any request
for multiple copies as given with the
If lp is specified as port@ machine (and rm is not in use), print data will be sent directly to the given port on the given machine.
Statistics on datafiles being received would be used on a print server, if you are interested in network performance between a variety of machines which are sending jobs to that print server. The print server could collect statistics on the speed of each print job as it arrived on the server.
Statistics on datafiles being sent might be used as a minimal accounting record, when you want to know who sent which jobs to a remote printer, when they were sent, and how large (in bytes) the files were. This will not give include any idea of how many pages were printed, because there is no standard way to get that information back from a remote (network) printer in this case.
Error messages sent to the console have a carriage return and a line feed appended to them, rather than just a line feed.
