R1 value, should test, because the printer model, the boundary of the print is different also, according to the actual situation to adjust,StretchDraw is the image automatically zoom, so the image bigger dots doesn't matter, does not affect the definition can be,

Thank you, I also are studying, it's a pity that the printer is bad, is taking...CodePudding user response:
Pixels per unit area associated with resolution, such as: resolution of 30 pixels/cm, 7 cm x 5 cm is 210 x150,The resolution of the concrete for the printer is printing,
CodePudding user response:
I use the getdevicecaps (HDC, vertsize) returns the height to width of setting up the printer,Getdevicecaps (HDC logpixelsx) back to 203 and 203 is the point of pixels per inch,
So, 70 mm=2.756 inch=2.756=560 * 203 pixels pixels,
Can that I painted image, with 560 pixels to paint?
The printer is out of order, temporarily can't test, dizzy dead.
