If what is reporting that is the Windows Printing sub-system, it may be an ambiguous message that has more to do with printer driver/application interface issues.
Saw it on a machine that was having other problems, so "the fix" was more general than addressing that specific error, but let me suppose what might be happening so that ou can look at your machine.
When a print job is generated, it is either directly sent [streamed] to the printer across the network, or is built on the computer and then sent to the printer as it signals that it is ready. If the print job is trying to be built on the machine, but there is an error in the sub-system (printing sub-system, printer driver, memory allocation) that gets perceived as a "out-of-memory" condition.
Since you have 8G, it is doubtful that print jobs are queued up and consuming memory.
One trick you can try is printing to another device, or install CutePDF, and print to PDF, and see if the print job goes. Also check your default printer inside of AC.
