Configuring LPD Printers
• If the data file arrives first, the access server sends the file to the printer
according to the printer setup on the port. When the control file arrives, the
access server sends the user data to the printer as the last page of the print job.
In this situation, the access server cannot display or use user information from
the control file while the file is printing.
Operation
The access server receives print requests from remote hosts on TCP port 515. It
uses LPD to send the file to a local printer through the access server’s LAN
interface and a serial port. Figure 15-1 shows what occurs when a host on the
LAN uses LPD to send a print job to the access server:
