We have a first gen Heidelberg 9110 with Version 4 software ON THE PRINTER. Can't upgrade since each version upgrade (currently 7.0) costs $$$$ which is a waste of money for a printer that's near it's EOL. We have used the same Dell PC with Windows 2000 SP2 since 2000 when the company purchased both products. Vista 64 bit drivers currently are available for the 7.0 version PC driver only. Version 4 is good for 2000, maybe XP.
So where did we spend our money? On THREE 250ppm b&w printers and a brand new Dell Studio PC with Intel Core i7 920, 6gb of ram, and Windows Vista 64bit OS. The problem is that this is to spool large files over as quickly as possible using PCL drivers. Variable addressing data per page. Times a few million, you get the idea of the number crunching. Only thing is we have a USB key with a license code to send this over to the printers for one PC. Can't use the old PC without ripping out the $30,000 license key and placing it back in the old PC to send files to the Heidelberg. Not an option at this point. Would Version 4.0 Win 2000 drivers work on Vista 64 bit? Haha, no. We could try the 7.0 64bit PC drivers (independent of the 4.0 software on the printer), but not sure they're all that compatible. Or downgrade to Windows XP 32 bit. Now you start to see the problem? We would lose half the ram on the PC if we downgraded and so a software hack might be useful in our case. Printer spool sizes do go up to 2gb from time to time and cause headaches with each page spooled around 100mb each. We can't wait 10 minutes sending files over. Personally, backwards compatibility is a dead issue if we get rid of the Heidelberg soon. Thrown over Niagara Falls preferably. :)
So, would all 6gb be helpful in this case? Would the hack help us spool large files?
