I have a Phaser 850 set up to print over the AppSocket port with
IFHP-3.3.19 and LPRng-3.6.23. The printcap follows the current
recommendation of letting IFHP make the connection to the 9100 port (see
printcap entry below). However, it seems that IFHP can't handle a
connection flakeout (to use the technical term) as well as LPRng can. I
just had a print job suck up 25% of the CPU on an Sun Enterprise 250
server (well, the CPU time was available, but still...) as it tried to
reestablish the connection at a rate of once every millisecond or two.
Here is a slice of the relevant log entries:
Filter_status: (of) connect to '129.83.149.81 port 9100' failed -
Connection refused at 13:05:45.691
Filter_status: (of) connect to '129.83.149.81 port 9100' failed -
Connection refused at 13:05:45.692
Filter_status: (of) connect to '129.83.149.81 port 9100' failed -
Connection refused at 13:05:45.694
Filter_status: (of) connect to '129.83.149.81 port 9100' failed -
Connection refused at 13:05:45.695
Filter_status: (of) connect to '129.83.149.81 port 9100' failed -
Connection refused at 13:05:45.697
This went on for about twenty minutes as the printer, reporting via it's
web interface, was first initializing and then cleaning.
Is there anything that can be done to prevent this? I am already using a
chooser script to make sure that the printer is up and listening on port
9100 before I release the job, so something must have happened to break
the connection. But can IFHP be configured to step back in some way?
Here is the printcap entry, in case you are interested:
