Inkscape does not seem to be printing to scale

Postby frostyfriday » Mon Mar 05, 2012 4:30 pm

Hi,

I have been trying to print a few business cards and am getting very frustrated trying to get the size of what I am drawing in inkscape to output correctly to my printer.
If I for example draw a large 6" x 6" square in the middle of my page, I find that after I print it, it is not 6" x 6", the printed version ends up being slightly larger and it's horizontal and vertical scales do not match, in other words it does not print square either.

I thought maybe my printer was just useless (Kodak esp7200) but then I tried the same thing using Libre Office Draw.
I got a perfect 6" x 6" square out of the printer!

So I have to assume Inkscape is not sending its image to the printer to scale.

Does anyone have any ideas as to how I correct this?
Right now I can fudge it and it will work but I cannot work this way for other things I want to do. I somehow need to make it so I can print to scale exactly.

Thanks,
Dennis

for the sizes to match, use the same dpi (physical dpi) for the document properties in inkscape as your printer. Or at least set the document dpi to be an even multiplier/divisor of the printer dpi. I say "physical dpi" because a lot of printers quote things like 4800dpi when that is not the actual dpi but simulated, and the actual dpi is much lower. It doesn't help that 16:9 LCD monitors stretch things, which means they'll look different on output to printer...but even then, when you create a perfect square or circle, it should look like a (almost) perfect circle or square on output.
