The limitation on the number of printers that can be attached to Windows NT print server is dependent on whether the print server is a Windows NT Workstation computer or a Windows NT Server computer. Windows NT Workstation and Windows NT Server have been optimized for different roles in the network:
The limitation on total printers attached to a Windows NT Server print server should be determined by daily requirements for print throughput. Print throughput is determined by the processor capabilities. For example, a print server with approximately 64 meg RAM and a 486/66 or higher processor with a high throughput network card can support 25 to 30 DLC printers or 40 TCP/IP printers.
