Comment 30 for bug 630639

just two comments:

>>same here. created black rectangle, with no filling and linewidth set to 0.5px

It is highly unlikely that this stroke width will work. As stated above, the stroke width must be 1 pixel or less in printer units, not Inkscape units. Inkscape resolution is 90 dpi. This means that if your printer resolution is 1200 dpi, which is fairly typical, then you will need to specify a stroke width, in Inkscape, of about 90/1200 = 0.075 px.

second comment, the option for Win32 Vector Print is not part of the normal priunt operation which is File->Print. It is part of the Python extensions system, obtained on the menu at Extensions->Export->Win32 Vector Print. Can you confirm that this item exists? It was committed at rev 11575. Also, you will need to ensure that your default printer is the laser printer. Under normal circumstances you should not need to "print to file" since I am assuming that your printer is currently connected. However this is your choice to make, depending on whether or not you are connected.
