Hi,
I am currently rebuilding the parport code with debugging
enabled. In the meantime, here is what I am seeing.
I get the following in my kernel log when booting:
Sep 28 11:07:00 aerie kernel: 0x378: FIFO is 16 bytes
Sep 28 11:07:00 aerie kernel: 0x378: writeIntrThreshold is 8

Sep 28 11:07:00 aerie kernel: parport0: assign_addrs: aa5500ff(08)
Sep 28 11:07:00 aerie kernel: parport0: No more nibble data (0 bytes)
Sep 28 11:07:00 aerie kernel: parport0: faking semi-colon
Sep 28 11:07:00 aerie kernel: parport0: Printer, HEWLETT-PACKARD DESKJET 710C
I have set up my printer queue, but all my tests
seem to fail to get to the printer (I never see
the printer's status light flash to indicate
communication in progress).
I have added my server name and localhost to hosts.lpd
and I my printcap contains:
##PRINTTOOL3## LOCAL deskjet 300x300 letter {} DeskJet Default {}
lp0|lp:\
:sd=/var/spool/lpd/lp0:\
:mx#0:\
:sh:\
:lp=/dev/lp0:\
:if=/var/spool/lpd/lp0/filter:
So I am wondering if the interrupt conflict is real and
preventing communication. It seems unlikely though, since
my system is able to read the printer model information
correctly.
When I ran printtool and went to create a "local printer"
queue, it detected the presence of /dev/lp0 and not lp1
or lp2.
/proc/interrupts shows no use of IRQ7:
CPU0
0: 2646217 XT-PIC timer
1: 3878 XT-PIC keyboard
2: 0 XT-PIC cascade
8: 1 XT-PIC rtc
9: 57168 XT-PIC serial
10: 1156 XT-PIC usb-ohci
11: 21 XT-PIC aic7xxx
12: 89870 XT-PIC PS/2 Mouse
13: 0 XT-PIC fpu
14: 45434 XT-PIC ide0
15: 8 XT-PIC ide1
NMI: 0
ERR: 0
/proc/dma contains:
4: cascade
Any help would be greatly appreciated.
