2 .SH NAME
3 laserbar \- produce bar codes on a PostScript laser printer
4 .SH SYNOPSIS
5 .B laserbar
6 [\fB-r\fP rotate] [\fB-x\fP xoffset] [\fB-y\fP yoffset]
7 [\fB-X\fP xscale] [\fB-Y\fP yscale] [\fB-lns\fP] string
8 .SH DESCRIPTION
9 .I Laserbar
10 prints on the standard output the PostScript text that will produce
11 (on a suitable laser printer) the \s-2CODE-39\s+2 bar code
12 corresponding to
13 .I string.
14 The \fBr\fP option may be used to specify a rotation (in
15 degrees) of the bar code.
16 The \fBx\fP, \fBy\fP, \fBX\fP, and \fBY\fP options may be used to specify
17 an x- or y-axis offset (in inches) or scaling factor, respectively.
18 (The offset is measured from the lower left corner of the page
19 to the upper left corner of the bar
20 code.  By default, the bar code produced is one inch high, and is scaled
21 so that the narrowest elements are each 1/72-inch \- i.e., one point \- wide.)
22 If the \fBl\fP option is specified, the bar code produced is labeled.
23 If the \fBn\fP option is specified, the resulting PostScript text
24 includes a leading \f(CWnewpath\fP command, so that the text may stand
25 alone or precede any other PostScript commands.
26 If the \fBs\fP option is specified, the resulting PostScript text includes 
27 a trailing \f(CWshowpage\fP command, so that the text may stand alone
28 or follow any other PostScript commands.
