Windows 95 Examples are provided for each of these environments In a Windows environment TCP IP is the data transfer protocol used for printing This means that IP addresses and netmasks are required in your Windows stations along with the appropriate TCP IP software This chapter will also discuss how you set this up in your environment Print Methods Overview A Central Host The recommended print method for a Windows environment is to have a central host act as a spooler for jobs before they are sent to the Print Server printer The reason for this is that the central workstation has the ability to store the spooled jobs while they are waiting to go to the Print Server printer The Windows Print Manager would rather see the data get spooled centrally rather than having to hold on to the data until the Print Server printer can accept it An example of this setup would be an Windows NT host which allows WfW stations to spool to it The NT host would have the only print setup going to the Print Server printer directly and it would be shared across the network In this way the WfW station could send jobs to this shared printer on the NT host All WfW jobs would first spool to the NT host before being sent to the Print Server printer for print ing Print Setup Possibilities There are two print methods available with the M208 in a Windows environment LPR Berkeley s Line Printer Protocol which uses TCP IP to transfer data to the Print Se
