DEFINING THE PRINTER TO THE HOST: TCP/IP ATTACHMENTXEROX DOCUPRINT 4850/4890 IPS INSTALLATION PLANNING GUIDE E-35References – OS/2The following IBM documents, referenced in this section, can provideadditional information on OS/2-to-IPDS printer connectivity.Printer Ensure that the Maximum Transmission Unit size (MTU) is aslarge as possible. A small MTU size increases the number ofpackets that are transmitted, allowing greater chances ofdegradation throughout the network. Increasing the MTU size inboth TCP/IP for OS/2 and the IPS printer may improve printerperformance.LAN If the printer is on a LAN that also has a large number of otherdevices attached to it, the high levels of traffic on the LAN cancause printer speed degradation. Consider moving the printer toa LAN that does not have so much activity on it.LAN-to-hostattachmentIf the speed of the link connecting the LAN with the printerattached to the OS/2 system is slow, this could be a bottleneck.Review your network configuration diagrams to look for anypotential bottlenecks.Table E-28.
