PRINT Print figure or model. Save to disk as image or M-file.
SYNTAX:
print
PRINT alone sends the current figure to your current printer.
The size and position of the printed output depends on the
figure's
PaperPosition[mode] properties and your default print command
as specified in your PRINTOPT.M file.
print -s
Same as above but prints the current Simulink model.
print -device -options
You can optionally specify a print device (i.e., an output
format such
as tiff or PostScript or a print driver that controls what is
sent to
your printer) and options that control various characteristics
of the
printed file (i.e., the resolution, the figure to print
etc.). Available devices and options are described below.
print -device -options filename
If you specify a filename, MATLAB directs output to a file
instead of
a printer. PRINT adds the appropriate file extension if you do
not
specify one.
print( ... )
Same as above but this calls PRINT as a MATLAB function
instead of
a MATLAB command. The difference is only in the parenthesized
argument
list. It allows the passing of variables for any of the input
arguments and is especially useful for passing the handles
of figures and/or models to print and filenames.
Note: PRINT will produce a warning when printing a figure with a
ResizeFcn. To avoid the warning, set the PaperPositionMode to
'auto'
or match figure screen size in the PageSetup dialog.
BATCH PROCESSING:
You can use the function form of PRINT, which is useful for
batch
printing. For example, you can use a for loop to create
different
graphs and print a series of files whose names are stored in
an array:
for i=1:length(fnames)
print('-dpsc','-r200',fnames(i))
end
SPECIFYING THE WINDOW TO PRINT
-f<handle> % Handle Graphics handle of figure to print
-s<name> % Name of an open Simulink model to print
h % Figure or model handle when using function form
of PRINT
Examples:
print -f2 % Both commands print Figure 2 using the default
driver
print( 2 ) % and operating system command specified in
PRINTOPT.
print -svdp % prints the open Simulink model named vdp
SPECIFYING THE OUTPUT FILE:
<filename> % String on the command line
'<filename>' % String passed in when using function form of
PRINT
Examples:
print -dps foo
fn = 'foo'; print( gcf, '-dps', fn )
Both save the current figure to a file named 'foo.ps' in the
current
working directory. This file can now be printed to a
PostScript-compatible printer.
COMMON DEVICE DRIVERS
Output format is specified by the device driver input
argument. This
argument always starts with '-d' and falls into one of several
categories:
Microsoft Windows system device driver options:
-dwin % Send figure to current printer in monochrome
-dwinc % Send figure to current printer in color
-dmeta % Send figure to clipboard (or file) in Metafile
format
-dbitmap % Send figure to clipboard (or file) in bitmap
format
-dsetup % Bring up Print Setup dialog box, but do not print
-v % Verbose mode, bring up the Print dialog box
which is normally suppressed.
Built-in MATLAB Drivers:
-dps % PostScript for black and white printers
-dpsc % PostScript for color printers
-dps2 % Level 2 PostScript for black and white printers
-dpsc2 % Level 2 PostScript for color printers
-deps % Encapsulated PostScript
-depsc % Encapsulated Color PostScript
-deps2 % Encapsulated Level 2 PostScript
-depsc2 % Encapsulated Level 2 Color PostScript
-dhpgl % HPGL compatible with Hewlett-Packard 7475A plotter
-dill % Adobe Illustrator 88 compatible illustration file
-djpeg<nn> % JPEG image, quality level of nn (figures only)
E.g., -djpeg90 gives a quality level of 90.
Quality level defaults to 75 if nn is omitted.
-dtiff % TIFF with packbits (lossless run-length encoding)
compression (figures only)
-dtiffnocompression % TIFF without compression (figures only)
-dpng % Portable Network Graphic 24-bit truecolor image
(figures only)
Other output formats are possible by using the GhostScript
application
supplied with MATLAB. For a full listing see the online help
for GHOSTSCRIPT, use the command 'help private/ghostscript'.
An example of some of the device drivers supported via
GhostScript are:
-dljet2p % HP LaserJet IIP
-dljet3 % HP LaserJet III
-ddeskjet % HP DeskJet and DeskJet Plus
-dcdj550 % HP Deskjet 550C (UNIX only)
-dpaintjet % HP PaintJet color printer
-dpcx24b % 24-bit color PCX file format, 3 8-bit planes
-dppm % Portable Pixmap (plain format)
Examples:
print -dwinc % Prints current Figure to current printer in
color
print( h, '-djpeg', 'foo') % Prints Figure/model h to foo.jpg
PRINTING OPTIONS
Options only for use with PostScript and GhostScript drivers:
-loose % Use Figure's PaperPosition as PostScript
BoundingBox
-append % Append, not overwrite, the graph to PostScript
file
-tiff % Add TIFF preview, EPS files only (implies -loose)
-cmyk % Use CMYK colors instead of RGB
-adobecset % Use Adobe PostScript standard character set
encoding
Options for PostScript, GhostScript, Tiff, Jpeg, and Metafile:
-r<number> % Dots-per-inch resolution. Defaults to 90 for
Simulink,
150 for figures in image formats and when
printing in Z-buffer or OpenGL mode, screen
resolution for Metafiles and 864 otherwise.
Use -r0 to specify screen resolution.
Example:
print -depsc -tiff -r300 matilda
Saves current Figure at 300 dpi in color EPS to matilda.eps
with a
TIFF preview (always at 72 dpi). This TIFF preview will show
up on
screen if matilda.eps is inserted as a Picture in a Word
document,
but the EPS will be used if the Word document is printed on a
PostScript printer.
Other options for figure windows:
-Pprinter % Specify the printer. On Windows and Unix.
-noui % Do not print UI control objects
-painters % Rendering for printing to be done in Painters mode
-zbuffer % Rendering for printing to be done in Z-buffer mode
-opengl % Rendering for printing to be done in OpenGL mode
A note on renderers: when printing figures, MATLAB does not
always
use the same renderer as on screen. This is for efficiency
reasons.
There are cases, however, where the printed output is not
exactly
like the screen representation because of this. In these
instances
specifying -zbuffer or -opengl will more likely give you
output that
emulates the screen.
For more help, type the command 'doc print' at the MATLAB command
line
for a complete list of devices and options. Also, see the Using
MATLAB
Graphics manual for more information on printing.
