Upgrading the Personal LaserWriter LS RAM does not provide a quantum improvement in performance because there is no processing capability on the printer I/O board, this is all handled by the computer to which the printer is connected.
The Personal LaserWriter LS I/O board only unbands the image as it is sent from the computer. Adding more RAM allows the printer to accept slightly larger documents.
A better way to improve Personal LaserWriter LS performance is to add RAM to or increase the performance of the computer to which the printer is connected.
