LW Select 360: Low Memory Causes ‘In Use‘ Light to Blink

I am trying to print my Desktop using QuickDraw GX with System 7.5. The document is getting spooled to the hard disk and the LaserWriter's 'Ready/In Use' light blinks, but it never prints. If I use the LaserWriter 8.1.1 printer driver, the Desktop prints within a minute.
In low memory situations when using QuickDraw GX this problem may appear. In order to correct this, send the following PostScript code to the printer.

Caution: If you choose to use the PostScript code provided in this article, you assume all risks involved in making these changes. PostScript code, if not entered correctly, can place the LaserWriter into a condition requiring service.

%=========================================================
% Begin PostScript Code
%
0 serverdict begin exitserver
<< /FactoryDefaults true >> setsystemparams
systemdict begin
realtime 10000 add
{ dup realtime le { pop exit } if } loop
quit
%
% end PostScript Code
