I guess the first thing to cover is, what are your system specs? [maybe you actually have low system memory]

The memory error could be misleading.
This could as well be a printer driver issue.
Hard to guess from the description since no information is given about the printer being used.
A printer driver update might help.
Can you do a screenshot (top bit) of the info Screen, you get this by holding Ctrl Alt and double clicking the 3rd mouse button. Will help.
Are you using colour views. this has caused problems for me in the past.
