OK. So how do I print a 4x6 borderless print on my new 7510 Photosmart? My only options seem to be a 4x6 tab print. What gives?
I don't have a 7150. However, you need to open the printer driver settings (Page Setup) from within the LR printmodule and select the borderless option and the correct paper size and orientation. Being back in LR you now can move the margin sliders to 0 and set the cell size to your paper size. You should see the results in the preview.
