I was printing with native Firefox 1.5.0.1 (FreeBSD 6.0) with CUPS, which Firefox sees and recognizes. The printer (Xerox N17, local, parallel port) started cycling through waiting-processing-waiting messages. Rebooting, I saw a message about an IRQ storm on the printer port being "throttled". Killing the job took care of this. Has anyone else had an issue like this? Firefox printing isn't critical but it's always nice to know what's going on. Oliver Incidentally, killing the job required a crash course in lppasswd and the cupsd.conf file, which I'll describe briefly here for the record... lppasswd stores encrypted passwords for cups administrative functions. The format is lppasswd -g group -a user. Permissions to various parts of the cupsd administrative functions (interface at http://localhost:631/admin) are set in the various location sections of /usr/local/etc/cupsd.conf. The various parameters than can be set are at http://www.cups.org/doc-1.1/sam.html.
