printdm — print .3d files on a dot-matrix printer
printdm [options] .3d file ...
Printdm produces output suitable for most dot-matrix printers, and also
for Canon BJ inkjet printers. It supports 8, 9, and 24 pin Epson-
compatible dot-matrix printers. The 9 pin dump is about 10% faster than
the 8 pin, but some old printers will not support it. Printdm supports
printers which support Epson’s ESC/P codes, and also those which
support IBM’s ProPrinter codes.
The configuration file print.ini, which sets various features for each
printer. See the ’Printer Settings’ section for details. Even if your
printer is not standard you should be able get it to work by
customising one of the supplied definitions.
The command line options are:
Only load the sub-survey SURVEY
select plan view
display station names
display crosses at stations
turn off the solid border around the edge of the survey.
Printing to dot-matrix and inkjet printers can be
significantly faster without this border as the printhead
usually doesn’t need to move all the way to the edge of the
If a printout takes more than one page, alignment ticks are
printed where the page corners need to be joined. By default
dash lines are also drawn along internal edges to facilitate
trimming down the page with scissors. If you have a
guillotine, the alignment ticks are sufficient for trimming
the page and this option allows you to turn off the dashed

When you run the printer driver you will be asked if you want a plan or
elevation (enter <P>, or <E>) - the default is plan. Then enter values
for the desired plot view. These values correspond to those displayed
in the bottom right hand corner when using Aven (or the top right when
using caverot). You would usually use Aven or caverot to pick the best
view and then note the angles before running the Printer Driver. This
will be integrated soon.
For a plan enter bearing up the page, in degrees, 0 indicating North at
the top of the page (the default).
For an elevation enter the angle of view (i.e. the compass bearing from
which the scene is viewed), and angle of tilt, where 0 is horizontal, -
is looking down from above, and + is looking up from below, so -90 is
the same as plan view.
For an extended elevation, no viewing angles are needed.
You’ll be told the scale needed to fit the plot on one page, and be
asked what scale you want to use. The you’re told how many pages this
will take (and the arrangement of those pages (e.g. 6 pages (2x3)) and
have the opportunity to print, quit, or change the scale (so you can
repeat this process until you have a scale and number of pages you are
You can then print all the pages, a range of pages, or any arbitrary
list of pages and ranges (handy for when your printer mangles a page).
Dot Matrix printers do not print to an accurate size - you need to do
to calibrate your printer in order to get correctly-scaled plots.
Print out a calibration plot using printdm --calibrate and measure the
width and height of the page border.
Then create an entry in /etc/print.ini or .survex/print.ini in your
home directory (Unix) or myprint.ini in the installation directory
(other platforms) with entries mm_across_page and mm_down_page
containing your values. The entry should look something like this:
Then run printdm --calibrate again, and check that the square is now
10cm wide and high. This calibration is particularly necessary for
older dot-matrix printers as they vary significantly in scaling - even
between two printers of the same make and model.
