my computer is not hooked up to a printer, so I have to take my patterns from Inkscape to my wife's computer to print them. Since she does not have Inkscape on hers, I have to convert them to pdf and put on a flash drive to get them over to hers for printing. I usually use the print icon, then select print to pdf, and save them to the flash drive. If you have not used Inkscape before, be aware that there is a rectangle in the drawing which is what will be printed to the pdf. Anything outside of the rectangle will not be printed. The size of this rectangle is selected from the file drop down, then document properties.
