Print Dialog Window
This dialog window can be used to set options and target before
printing the current graph in PostScript® format. The graph
can be sent either to a PostScript® printer or saved in a file
for import in another program which is able to import the
notes about PostScript®
below for more information.
You cannot directly send the graph to the printer here, if it does
not support PostScript®.
In this case you have to use third-party software installed on your
computer which has printer access.
Either print the graph in PostScript® format to a file in this
dialog (if your software can import PostScript® or use
to create a file in the more common GIF, TIFF or
Afterwards import this file in your third-party software and
print the graph there.
Initially, the options in this dialog are set so the graph
is sent to a printer, fits on the page according to the specified
size and is centered on the page. Before printing, the user is
able to modify these settings. Beside using the window's dialog
items, this can also be done with direct manipulation of the
"paper picture" in the lower part of the window:
The measure unit (either cm or inch) and the print command can be
set in dialog
Click on the symbolized graph (on the paper symbol) to switch
the "Center Graph on Page" check button.
Click on the paper symbol (i.e. on the border around the graph)
to switch the "Page Orientation" option button.
Click on the symbolized printer or disk icon to switch the
"Send to" radio buttons.
Dialog Elements of the Print Window
Specifies the size of the page used for printing the graph,
either A3, A4, A5, Letter or Legal. Please refer to your printer
documentation to choose the appropriate value.
The resulting page size (in cm or inch) is displayed in the window.
This size is used to center the graph correctly on a page and has
no effect when the "Center Graph on Page" check button is not
Specifies the orientation of the graph on the page, either
Landscape or Portrait. The resulting page width and height
(in cm or inch) is displayed in the window. The initial orientation
is set automatically to get a maximal scale (e.g. Landscape, if
the graph height is smaller than the width).
Center Graph on Page
Select this check button to center the graph on the page. You
have to choose the right page size of your printer to get
proper results. Usually, centering is desired when a graph
is printed on paper, but not when a PostScript® file is
imported in another application. So, if the user switches the
"Send to" radio buttons, then this check button is automatically
set (centered for printers, not centered for files).
Of course, this automatic setting can be corrected afterwards.
This slider sets the scale in the PostScript® representation
of the graph. The "Fit to Page" button calculates the maximal
scale where the graph is completely visible on the page (but
not larger than a scale of 1:1). This is also the scale used
as initial value. After manipulating the scale, the actual width
and height of the graph will be displayed (in cm or inch) in
the picture in the lower part of the window.
Width and height are drawn in red when the graph exceeds the
current dimensions of the page.
A special scale is 1:1 where one inch on the screen is one inch in
the generated PostScript® file (for 72dpi screens).
To get this scale, simply click on the 1:1 label.
the uDraw(Graph) PostScript® interface has a minimal scale
with a magnification rate of 0.1 which is the "Small" value of
the scale slider. No smaller scales are supported, so very large
graphs may not fit on the page of the selected size.
The "Fit to Page" button does not reduce the scale if the scale
slider is already at the minimal value.
Choose a larger page size or do not use the "Center Graph on Page"
option in this case.
With these radio buttons you can choose the mode that is used for
The mode is independent of the printers capabilities, so "Color"
can be printed on a b/w printer and "Grayscale" can be printed on
a color printer (which should give you identical color-less results).

Notes about PostScript® in uDraw(Graph)
The output generated by uDraw(Graph) is PostScript® Level-1 code,
compliant to the Adobe® Document Structuring Conventions (DSC).
To output is compliant to the guidelines for document exchange in
"Encapsulated PostScript Format" (EPSF, often called EPS), so you
can load a PostScript® graph created by uDraw(Graph) in third-party
software that support EPSF import.
The optional PostScript® preview part ("Encapsulated PostScript
Interchange", EPSI) is not generated, so after importing a
PostScript® graph created by uDraw(Graph) you may not see the
graph on the screen, but it will appear on paper after printing.
You can use third-party software packages to add the optional
preview part to any PostScript® file, e.g. "pstoepsi".
Please use a web search engine to find such software for your
uDraw(Graph) usually places a graph on one PostScript® page,
regardless of the size of the graph visualization, so multi-page
output for getting huge posters is not directly supported.
You can use third-party software packages to split a large
PostScript® file on several pages (to stick them together),
Please use a web search engine to find such software for your
If the PostScript® scale you have selected with the "Print Scale"
slider is too large, then the graph will not be completely visible
on the page after printing.
If you intend to send the graph to a printer, choose a suitable
page size supported by the printer and press the "Fit to Page"
button afterwards to avoid such problems.
The coordinates of nodes and edges in PostScript® are taken from
the screen representation of the graph.
PostScript® fonts and screen fonts may vary in character width,
so for the PostScript® graph it is possible that the text of a
node is quite smaller than the node itself, in opposition to the
In rare cases, the text may overlap the boundary of a node.
Screen font "Helvetica" is always replaced by the PostScript®
font "HelveticaNarrow" to avoid problems with overlapping.
The uDraw(Graph) default font "Lucida" is not a popular font in
So, the PostScript® files generated by uDraw(Graph) will always
check if the PostScript® interpreter in use (e.g. the printer)
supports "Lucida" and will use font "Helvetica" otherwise.
