.TH LASERBAR 1 .SH NAME laserbar \- produce bar codes on a PostScript laser printer .SH SYNOPSIS .B laserbar [\fB-r\fP rotate] [\fB-x\fP xoffset] [\fB-y\fP yoffset] [\fB-X\fP xscale] [\fB-Y\fP yscale] [\fB-lns\fP] string .SH DESCRIPTION .I Laserbar prints on the standard output the PostScript text that will produce (on a suitable laser printer) the \s-2CODE-39\s+2 bar code corresponding to .I string. The \fBr\fP option may be used to specify a rotation (in degrees) of the bar code. The \fBx\fP, \fBy\fP, \fBX\fP, and \fBY\fP options may be used to specify an x- or y-axis offset (in inches) or scaling factor, respectively. (The offset is measured from the lower left corner of the page to the upper left corner of the bar code. By default, the bar code produced is one inch high, and is scaled so that the narrowest elements are each 1/72-inch \- i.e., one point \- wide.) If the \fBl\fP option is specified, the bar code produced is labeled. If the \fBn\fP option is specified, the resulting PostScript text includes a leading \f(CWnewpath\fP command, so that the text may stand alone or precede any other PostScript commands. If the \fBs\fP option is specified, the resulting PostScript text includes a trailing \f(CWshowpage\fP command, so that the text may stand alone or follow any other PostScript commands. .P This manual page (if it appears with a bar code printed on it) was produced by something like the following sequence: .IP .ft CW laserbar -x 2.5 -y 3 -l -n ABC123xyz > tempfile .br troff -man -Tpost laserbar.1 | dpost >> tempfile .br prt -dprinter -lpostscript tempfile .ft P .SH SEE ALSO laserbar(3), prt(1), dpost(1), postbgi(1), postprint(1), postdmd(1), posttek(1), etc.
