I have two windows 2003 servers that print to the same printer (an HP Laserjet 4250). The printer is rated at 40+ pages per minute. When server 1 prints to it, it prints at the rated speed. However, server 2 prints at a much slower speed -- about 15 to 20 pages per minute. When I pause the printers and examine the spool file after it has been generated, the spool file on server 2 is twice the size of the spool file on server one. I am, obviously, using the same document on both servers and have verified that the document is the same size on both servers.
I updated the print driver on both servers to the same version, check the preferences to ensure they match, and set the options on both servers to use the same print processor. However, the problem persists.
What could cause the spool file to be twice as large on one server as on the other?
I know that you said you set them up the same, but since they're not behaving the same, and you are asking for help, I'm going to assume that something has been overlooked, so please don't be offended if I mention something that you've already checked:
Something that was not clear from your question is whether the two servers are doing the printing, or if a client is printing to the printer via the two servers' print queues. If printing from a client you should remember that while the servers may be configured identically, you may have an obscure setting on your client machine for only one of the printer connections that may be overriding one or more of the default options set on the server. To be sure, you may want to try doing the following on the client machine:
If printing directly from the two servers, you may want to also check to ensure that the software doing the printing (e.g. Word, Acrobat, etc.) is exactly the same version and also configured exactly the same on the two servers.
I'd export the printer-related registry entries from both server computers (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86\Drivers\Version-3, assuming they're 32-bit drivers) and compare the portions that relate to those printers between the servers.
