NAME

       postdaisy - PostScript translator for Diablo 630 daisy-wheel files

SYNOPSIS

       postdaisy [-c num] [-f num] [-h num] [-m num] [-n num] [-o list] [-p mode] [-r num] [-s num] [-v num ] [-x num] [-y num] [file...]

       /usr/lib/lp/postscript/postdaisy

DESCRIPTION

       The postdaisy filter translates Diablo 630 daisy-wheel files into PostScript and writes the results on the standard output. If no files are
       specified, or if - is one of the input files, the standard input is read.

OPTIONS

       -c num	Print num copies of each page. By default only one copy is printed.

       -f name	Print files using font name. Any PostScript font can be used, although the best results will be obtained only with  constant-width
		fonts. The default font is Courier.

       -h num	Set  the initial horizontal motion index to num. Determines the character advance and the default point size, unless the -s option
		is used. The default is  12.

       -m num	Magnify each logical page by the factor num. Pages are scaled uniformly about the origin, which is located  near  the  upper  left
		corner of each page. The default magnification is  1.0.

       -n num	Print num logical pages on each piece of paper, where num can be any positive integer. By default, num is set to  1.

       -o list	Print  pages whose numbers are given in the comma-separated list. The list contains single numbers N and ranges N1 - N2. A missing
		N1 means the lowest numbered page, a missing N2 means the highest. The page range is an expression of logical  pages  rather  than
		physical  sheets of paper. For example, if you are printing two logical pages to a sheet, and you specified a range of 4, then two
		sheets of paper would print, containing four page layouts. If you specified a page range of 3-4, when requesting two logical pages
		to a sheet; then only page 3 and page 4 layouts would print, and they would appear on one physical sheet of paper.

       -p mode	Print files in either portrait or landscape mode. Only the first character of mode is significant. The default mode is portrait.

       -r num	Selects  carriage  return  and	line  feed behavior. If num is 1, a line feed generates a carriage return. If num is 2, a carriage
		return generates a line feed. Setting num to 3 enables both modes.

       -s num	Use point size num instead of the default value set by the initial horizontal motion index.

       -v num	Set the initial vertical motion index to num. The default is  8.

       -x num	Translate the origin num inches along the positive x axis. The default coordinate system has the origin fixed near the upper  left
		corner	of  the  page, with positive x to the right and positive y down the page. Positive num moves everything right. The default
		offset is  0.25 inches.

       -y num	Translate the origin num inches along the positive y axis. Positive num moves text up the  page.  The  default	offset	is   -0.25
		inches.

EXIT STATUS

       The following exit values are returned:

       0	       Successful completion.

       non-zero        An error occurred.
