I've written several SR10 print servers (for commercial use, sigh).
If yours is running slowly, my bet would be that the -orient land
switch is causing the bitmap to be rotated 90 degrees from the
original, and that the DN3000 doesn't have enough memory to hold
both the original and the rotated bitmap during the transform.

A regular 8-plane screen dump is 800 Kb (low res color) to 1200 Kb
(high res color), and should not cause any problems on a 6 MB node
(unless the print server is magnifying first before rotating ... but
*that* would be stupid!). 24-plane bitmaps are another story. They
would definitely send your machine into a frenzy of network paging.

Try printing with -orient portrait. See if this speeds things up.
Also try running "dspst -a" and see if your page-purifier processes
are running a lot.
