.SH SYNOPSIS
\*(mBprintfont\f1
.OP "" options []
.OP "" files []
.SH DESCRIPTION
.B printfont
builds a PostScript program that prints character set tables for
one or more PostScript fonts.
The program is written on the standard output,
and when sent to a PostScript printer usually prints a 16\(mu16 table
that shows the available (encoded) characters in each font.
The following
.I options
are understood:
.TP 1.0i
.OP \-a num
Set the character cell axes mode to
.IR num .
0 disables axes printing, 1 draws a baseline,
2 adds a vertical line through the character origin,
and 3 adds a vertical line through the next character origin.
The default is 0.
.TP 1.0i
.OP \-b num
Print each table in base
.IR num .
The base determines the number of rows and columns in the table.
It also affects the character code placed in the lower left corner of each cell.
The default is 16 (hexadecimal).
.TP 1.0i
.OP \-c num
Print
.I num
copies of each page.
By default only one copy is printed.
.TP 1.0i
.OP \-f name
Use font
.I name
for labeling the tables.
The default font is Helvetica.
.TP 1.0i
.OP \-g num
Use
.I num
as the gray level for marking cells not currently assigned to characters.
The gray level should fall between 0 (black) and 1 (white).
The default is 0.85.
.TP 1.0i
.OP \-m num
Magnify each logical page by the factor
.IR num .
Pages are scaled uniformly about the origin,
which is located near the upper left corner of each page.
The default is 1.0.
.TP 1.0i
.OP \-p mode
Print
.I files
in either \*(mBportrait\fP or \*(mBlandscape\fP
.IR mode .
Only the first character of
.I mode
is significant.
The default
.I mode
is \*(mBportrait\fP.
.TP 1.0i
.OP \-v
Completely label each character cell.
The full character name goes in the upper left corner and the
character width (at point size 1) goes in the lower right corner.
.TP 1.0i
.OP \-w num
Set the line width to
.I num
points, where a point is approximately 1/72 of an inch.
A line width of 0 means 1 pixel.
The default line width is resolution dependent.
.TP 1.0i
.OP \-x num
Translate the origin
.I num
inches along the x axis.
Positive
.I num
shifts the table to the right.
The default offset is 0.
.TP 1.0i
.OP \-y num
Translate the origin
.I num
inches along the y axis.
Positive
.I num
shifts the table up the page.
The default offset is 0.
.TP 1.0i
.OP \-C file
Copy
.I file
to the output file;
.B file
must contain legitimate PostScript.
.TP 1.0i
.OP \-E name
Set the character encoding for text fonts to
.IR name .
Requesting
.I name
means include file
.MI \*(dQ/ name .enc \f1.
A nonexistent encoding file is silently ignored.
The default selects file
.MR \*(dQ/Default.enc .
.TP 1.0i
.OP \-L file
Use
.I file
as the PostScript prologue.
.br
The default is
.MR \*(dQ/printfont.ps .
.PP
Arguments should be PostScript
.I font
names or the word
.MR all ,
which means the full set of
.SM ROM
and disk based fonts available on a printer.
.B printfont
prints one font table per page.
Each page is labeled with the
.I font
name, the printer product name and interpreter version number,
and the gray level, linewidth, and printer resolution.
.PP
Black cells are used to mark characters listed in the font's
.MW Encoding
array but missing from its
.MW CharStrings
dictionary.
They usually indicate an incomplete font or a mistake in the
.MW Encoding
array.
The check is skipped if the font doesn't include a
.MW CharStrings
dictionary.

.SH EXAMPLES
Print the characters available in the Times-Roman, Symbol and
ZapfDingbats fonts:
.EX
printfont Times-Roman Symbol ZapfDingbats | lp ...
.EE
Print a baseline under each character and fully label the cells:
.EX
printfont -a1 -v Times-Roman Symbol ZapfDingbats | lp ...
.EE
Dump all the fonts available on a printer using the Latin1 character encoding:
.EX
printfont -ELatin1 all | lp ...
.EE
.SH WARNINGS
Printing a single table can take several minutes.
Dumping all available fonts can tie a printer up for an hour or more.
