You still have to configure the driver for the type of paper and size. These can then be incorporated into a LR print template. You cannot specify the paper size in LR otherwise (I know this from when I first tried to print something and there was a mismatch between the LR standard size that was selected and what the printer was expecting via the driver. Of course once you have everything properly configured you don't have to revisit the driver at all.
A print template in LR can be set for everything; print size, profile, rendering intent etc; to the degree all you have to do is simply press the "
Print" button, nothing more after just selecting images to actually print in the filmstrip.
What you don't want is the driver setup for (in this example, an Epson) any preset
but for
Default Settings. Different in Photoshop where you might very well want a preset named say
Luster Paper (for that media settings and all associated setting for Luster), and
all the other configurable items in that print dialog. Not in LR.
