.TH LASERGNU l .SH NAME lasergnu \- send gnuplot output to a printer .SH SYNOPSIS .B lasergnu [ flags ] plot-command... .SH DESCRIPTION .I lasergnu runs .IR gnuplot (1) in an environment to produce typeset output on an IMAGEN or Postscript printer. .PP The .B gnuplot commands .B plot-command are performed and the output sent to the printer. If the .B -f option specifies a file for input, the plot command is optional. The command-line plot commands are executed prior to any in the file(s). .PP For example, to plot the function .I sin(x) from -1 to +1, and to use printer im1, use the command .br .nf lasergnu -Pim1 'plot [-1:1] sin(x) with lines' .fi To execute the gnuplot command file .I myplot, on the postscript printer lw0, use the command .br .nf lasergnu -Plw0 -p -f myplot .fi The following switches are recognized: .TP .BI \-p Use the postscript language to make the plot, instead of Impress. This is for use on Postscript printers only. This uses a double-size plot in landscape mode as the default. .TP .BI \-P\0 printer The output of this program is intended for .I printer. \ If the file is being spooled, this determines the printer it is spooled to (default: $LASER). Be sure to use the -p flag if the printer is a postscript printer. .TP .BI \-f\0 file Take gnuplot commands from the named file. Multiple files may be supplied with separate -f options. .TP .BI \-t\0 title Specify the title of the plot. .TP .BI \-b Do not print a banner page. .TP .BI \-J Do not print a banner page. .TP .B \-help Prints a list of options. .SH SEE ALSO gnuplot(l), lpr(1)
