Close...

Either the printer would need to have enough memory to model the entire page,
or the image would have to be transmitted by columns (instead of rows) to
deal with graphics in landscape mode.  Transmitting the image by columns in
landscape mode is the same problem (for the application programs) as
transmitting it by rows in portrait mode.

PS.  Thanks for reading the manual first, but the HP Personal Peripheral
Assist Line should be able to answer questions like this one.  You pay
for the call to (208) 323-2551, but there's no charge for LaserJet support.
