Ohh ! sorry just slipped out...
As far as i understand , the /etc/printcap contains a spec of the printers
capability eg. name of the spooling directory etc... when a lpr command is
issued , the files to be printed are copied to the spooling
directory,specified in the printcap. lpr also creates a 'control file' in
addition to copies of the files to be printed.This cont' printing parameters
for the lpd. The lpr then sends a sends an IPC message to the line printer
dameon(lpd).The daemon process does a fork of itself & handles the
request,while the original lpd , waits for other print jobs. The forked copy
of the lpd looks at the files in the spool directory & sends them to the
actual printer.
Now if some thing's screwed in the printcap, it may cause unexpected
results. Or if the buffers arn't flushing .... I correct myself
fflush(NULL) , might work.
