There is no place you can specify the printout size of a floor plan.  DecoTech simply prints what you see on your screen.  A wider screen offers a wider working area.  To fit a wider floor plan on the same paper sheet size, DecoTech has to resize it.  This is why it covers less space on the page.  If you use a 8.5"x14" sheet instead of a 8.5"x11" sheet, the floor plan will cover more space because the 8.5"x14" sheet dimensions are more like the wide screen dimensions.

There is two tricks you can try to get your wide (16:9 ratio) floor plan printed as a normal (4:3 ratio) floor plan.  First trick is fast an easy to remember.  Second trick is long, complicated and hard to remember but it can let you specify the exact printout size you want.

1st trick: Fast an easy to remember

The image below shows how Scene Editor program looks on a wide 16:9 screen.  The scale value indicates the number of units that fits horizontally on the displayed floor plan.  As you see the floor plan is clipped at top and bottom because this project has been created on a normal 4:3 screen with a specific scale value for that screen size.

Note: On a 16:9 screen, to see the same amount of units displayed vertically as on a 4:3 screen, the scale value must be multiplied by (16x3)/(9x4) = 48/36 = 4/3.  So a scale of 240 on a 4:3 screen needs to be 320 on a 16:9 screen to avoid any vertical clipping.

The floor plan printout is identical as what you see on your screen.  To make the printout less wide you simply need to make the displayed floor plan less wide on your screen.  When you run Scene Editor program it always uses the maximum available area of your desktop.  So you need to reduce your desktop size before running Scene Editor program.

Note: The printing process always tries to use the maximum printable area while keeping the same aspect ratio of your displayed floor plan.  So it scales up the image until the first of its width or height reaches the printable area width or height respectively.

To reduce your desktop size, make a right click on an empty spot on the task bar until you get a popup menu with the Lock the Taskbar option.  Uncheck the Lock the Taskbar option.

Hold down a left click on an empty spot on the task bar and move it at the right of your screen, then release the left click.  Move the mouse pointer over the left edge of the taskbar and resize it to 1/4 of your screen width.  Your desktop size will now be 3/4:1 of 16:9 so 12:9 = 4:3.

Run the Scene Editor program.  As you see it now appears as on a 4:3 screen.

Again the floor plan printout is identical as what you see on your screen.  You may need to change the scale value before printing to get bigger details of floor plan.  See also Tip #2 in the Tips Spot.

2nd trick: Long, complicated, hard to remember but very accurate.

Instead of printing the floor plan directly you can save an image of it with specific dimensions.  But you need to know your current printer resolution (Dots Per Inch) and its maximum printable area.  In the example below we use an hypothetic printer capable of 300 DPI with a printable area of 10.5"x8".  Since we want the biggest possible printout we will create and image of 300x10.5 X 300x8 = 3150 X 2400 pixels for landscape printing.  Select the Print button.  The floor plan image is saved and its proportions are independent from the displayed floor plan proportions.

From here you can use any other 3rd party programs to load and print the floor plan image.  You can also load it and print it with the Scene Editor program.  Simply load the floor plan image the same way you load 3D perspective images.  The floor plan image will probably appear very huge on your screen.  Use the scroll bars to move the image.

If you notice that the text size on the floor plan image is too small, then you will need to temporary increase the text size, redo the floor plan printing/saving image, then set back the text size to its previous value.

To change text size, select the top center Options button, then the Miscellaneous Options button, then the "Configure the size of the lettering on the floor plan..." button.  Default value is 9 points.  (Example: If the text size on the floor plan image appears to be 1/3rd of normal compared to objects around, then multiply the lettering height by 3.)

Once you are satisfied with the floor plan image, print it the same way you print a normal 3D perspective except that you need to change the Print quality to Use the current displayed image and apply anti-aliasing.  Once the printout is done, set back the Print quality to is previous value then select the Close button.  (Default value is Create an image using 50% of printer resolution. (Medium).)

Note: The printing process always tries to use the maximum printable area while keeping the same aspect ratio of your displayed 3D perspective.  So it scales up the 3D perspective until the first of its width or height reaches the printable area width or height respectively.
