.SH Description
This Bourne shell script can be called by the
.PN lpd
line printer daemon to invoke the appropriate translator to convert each
data type to PostScript.
The data type passed by
.PN lpd
may be specified by using the
.PN lpr
command with the \fB\-D\fIdatatype\fR option,
or by using the \fBDa=datatype\fR capability in the
.PN printcap
file.
.PP
For a file in a data syntax to be translated to PostScript, the
.PN xlator_call
script must contain a case branch which recognizes the data type string and
calls a suitable filter.
The supplied
.PN xlator_call
recognizes the ANSI, ASCII, ReGIS and Tektronix 4014 data types.
