> 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.

You can back this off to 500 milliseconds safely. I will put this into
the next release.
