I am only guessing: You use your parallel port in polling mode (i.e. without an IRQ) and while printig both via parallel port and via USB the data transfer via parallel port starves.
According to dmesg, parport0 does has an interrupt but is using polling mode. I checked out /etc/modules.conf but it's empty. (Should it be?) Except for compiling a new kernel, I'm not sure how to change this.
Note that when a backend exits with non-zero exit code then the cupsd disables the queue - see
Thanks for the info. Since I have Webmin installed, I can check the printer configuration to find out if the queue has been disabled and re-enable it from there. So I do have a partial solution to my problem. Thanks! Christopher Reimer
