The LaserWriter Select 310 does not support the LaserWriter 8.x printer driver, and so does not support a lot of the features you asked about.
* Can the Select 310 use an "installed and preferred" option for selecting
paper trays as does the LaserWriter 8.x driver?
This is not possible as the LaserWriter Select 310 driver does not
save any preference information in the LaserWriter 8 Prefs file as does
the LaserWriter 8 driver, nor does it have the "Auto Select" feature to
execute it.
* Can the Select 310 driver continue to draw paper from an additional
cassette if the first cassette runs out?
No. Tray Switching is not implemented in the LaserWriter Select 310
Driver.
* Can the 310 draw the first sheet from one tray and all remaining pages
from a second tray?
This is a built-in feature of the LaserWriter Select 310 driver and can
be used via the Print dialog box.
* Can the Select 310 handle "n-up" reductions when printing multiple pages?
No. This feature was not implemented in the LaserWriter Select 310
driver, so you cannot print multiple pages on one sheet of paper.
* Does the Select 310 offer any kind of resolution enhancement?
The only type of enhancement offered is via the ability to change "Print
Density" in the Options dialog within the Print dialog.
* Is Apple considering releasing a serial version of the LaserWriter 8.x
driver?
No, Apple has no plans to release a serial version of the LaserWriter 8.x
printer driver.
