How to print this map (page) to 1:500 without georeferencing or without using any gis software. It is better to say that the marked line of 3 km should be 6 cm on paper (A4).

2Iterate: Make a few prints in different sizes. Measure. Adjust if necessary. Print again. Repeat until you are satisified. Shouldn't take too long to get it accurate enough. If you need more precision than that, any GIS software and georeferencing is probably the easiest way to go.– MartinCommented Aug 18, 2014 at 9:30

+1 to Martin's method. Otherwise, to save paper, check the scales corresponding to your zoom level here: gis.stackexchange.com/questions/7430– julienCommented Aug 18, 2014 at 9:53

1Also, the marked line on the map is actually 750 meters according to the notations on the line. If that is the intended scale, it should be 1,5 cm and not 6 cm (1:500).– MartinCommented Aug 18, 2014 at 10:14

let say i need consider that segment is 3km on ground. how could i achieved it to 6cm on paper. any sound trick for it.– GIS Data ButcherCommented Aug 18, 2014 at 14:56

Since you're basically just wanting to print an image at a certain size, this has nothing to do with map scale or GIS and could be done with any image editing software, or with any software that allows printing at a percentage size if you do the math.
You could use GIS or CAD or any number of things to accurately scale the image (georeferencing is totally unecessary). As Martin points out, the line notation says that distance should be ~750 meters, so if you print it at 6cm it's not 1:500 scale. And the helpful link Julien provided will be of no use to you without figuring out what the scale should really be.
You've got a distance on the image you want to be 6cm when printed. I will assume that the original 928x580 pixel version (not the 630x394 reduced size shown on this page) of that image you uploaded is what you're trying to print. Zoomed in to 300% I measure that line as 6.83cm (for the record, my image software is assigning or reading a resolution of 96.something ppi for the image, which is probably right if this is a screen capture). This measurement could also be derived by printing it once at 100% and measuring it on the paper - no need for iterative printing really. You want it to be 6cm, so 6/6.83 = 0.878477, so you need to print the image at 87.8% of full size - either by using the scale option in a print dialog or actually resizing the image.
