Windows NT and Windows 95 network clients can send print jobs using any of the following network protocols:
Windows NT 4.0 print clients now use enhanced metafile (EMF) data type instead of RAW. EMF allows the print job to be spooled to the server and rendered at the server into the appropriate print format. Remote rendering significantly speeds up the client computer's return to task.
Windows NT and Windows 95 network clients need not worry about printer drivers, because if the client doesn't have a needed driver it is automatically installed on the client's hard disk from the Windows NT 4.0 server when the client begins its print operation. If, however, the client computer is running Windows NT 4.0 and the server is running an earlier version, the printer drivers won't work. A Windows NT 4.0 print server can supply earlier version of printer drivers where necessary, but a Windows NT 4.0 client cannot use earlier versions of printer driver.
Windows 95 print jobs always spool EMF locally and playback locally to generate RAW data type before being sent to the print server. The print server spools them again.
The Windows NT print server receives print jobs from Windows 95 clients through the Windows NT Server service.
