Okay, i figure this is probably one of the best places where i will get a good answer.
Basically on experts-exchange a guy and I are disagreeing about adding memory to postscript printers.
A person orginally asked a question regarding his current postscript printer. He has a laserjet 4ml which is a older postscript printer with 4 megs of ram which does 4ppm (at best). Anyway he is printing from an old beige g3 with os 8.6 or 9 i belive using the laserwriter driver.
Anyway, the issue at hand is that when he prints large complex pdf documents (ranging from 1 meg to 3 or 4 megs in size) it bogs his computer way down. He can barely do anything until the job is complete and porints. Then control is restored to the computer and he can continue.
Well I suggested that he replace the 4ml with a 5M which is a 12 ppm 6 meg base postscript laserjet. But i also suggested that he max out the ram so that he ends up with 52 megs of ram on the printer which i theroized would help restore control of the computer since the mac can spool all the data from the print jobs to the printer with having a lot of memory. My theroy is that the 4ml was bogging down with only 4 megs of memory on the large postscript jobs.
But this other tech is disagreeing with me. His statement is as follows:
" agree with the comments on the 5m, but I'm afraid I have to disagree with the RAM issue. In general, adding extra RAM to a PostScript printer does not change the speed at all. Neither does it let the printer process more complex or larger documents.
A PS printer processes commands one at a time and cannot use more RAM to process that command faster. Once the command has been processed it is discarded, freeing up the RAM used."
He also states this:
"Yes, what I am saying is that "a huge postscript document made up of complex tiffs and eps images and whatnot will take just as long to print and it won't hog the computer's resources while its spooling". It really is as simple as that. Note that, if you are using PCL (HP's printer language) there are reasons for adding extra memory; but with PostScript, once you have enough, any more is overkill.
First of all, the spooling is done by your PC (and/or the server). When you click on "Print", the application creates a print file. Once that is done, the PC is free to do whatever it wants. Spooling that file onwards takes a negligeable amount of processor power."
So my basic question is this, is adding more memory to a laserprinter (say over and above the 6 megs of the base 5m) overkill and won't make a difference when printing to the 5m from an old beige g3 using the laserwriter driver?
And if you do answer, i would like it to be somewhat detailed only because this gentleman has a lot of experience and points on EE and i am disagreeing with a "guru".
If I am wrong then thats fine, i learned something new about Postscript.
