[gentoo-user] lp unable to detect parallel printer hp 710c

[gentoo-user] lp unable to detect parallel printer hp 710c

[Michael [Plouj] Ploujnikov]

I am having this issue on gentoo-sources 2.6.17-r4:
http://dev.gentoo.org/~dsd/genpatches/issues-resolved.htm#2.6.9-lp

My HP 710C parallel port printer is not being detected.

This used to work on my system before, but then I had the 2.6.16-r9
kernel and since them I had to re-install my Gentoo. I tried
re-compiling the 2.6.16-r9 kernel using a backed up config, but it
doesn't seem to detect my printer anymore.

I tried a recent Ubuntu live cd 6.06 and it successfully detected my printer.

current dmesg:
...
Allocate Port Service[0000:00:0e.0:pcie03]
lp: driver loaded but no devices found
Real Time Clock Driver v1.12ac
ACPI: Power Button (FF) [PWRF]

serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
parport: PnPBIOS parport detected.
parport0: PC-style at 0x378, irq 7 [PCSPP(,...)]
lp0: using parport0 (interrupt-driven).
PNP: PS/2 Controller [PNP0303:PS2K] at 0x60,0x64 irq 1
...

I am very sure I enabled all the proper kernel things as described by
the printing guide. I also enabled PNP as suggested by someone
(http://gentoo-wiki.com/HP_Deskjet_720C_with_CUPS):

$ grep -i pnp /boot/config-2.6.17-gentoo-r4
# CONFIG_IP_PNP is not set
CONFIG_PNP=y
# CONFIG_PNP_DEBUG is not set

# CONFIG_I2C_PARPORT is not set
# CONFIG_I2C_PARPORT_LIGHT is not set
# Partition Types
# CONFIG_PARTITION_ADVANCED is not set
CONFIG_MSDOS_PARTITION=y

Has anyone experienced similar problems?

I would like to report this a kernel bug, but since I couldn't get the
previous working kernel to work this time, I can't do that.


Thanks.

Just checking - have you also set CONFIG_PRINTER=y ?

You need this.

You also need CONFIG_PRINTER (Parallel printer support under Character
Devices) if you don't already have it.

Wow, indeed enabling this allowed lp to detect my printer again!
I didn't know about this before, nor did the Gentoo printing guide
mentioned it. I am sending an email to the authors of that guide to
include a note about IEEE 1284.

Interestingly enough, my previous install, which used 2.6.16-r9 does
not have this setting set, but the config file mentions it and my
printer worked fine.

I did find info that my printer does use IEEE 1284:

Always had this enabled :)

It appears I actually still cannot print to this printer. I checked
dmesg again and I noticed this:

lp: driver loaded but no devices found
Real Time Clock Driver v1.12ac
ACPI: Power Button (FF) [PWRF]
ACPI: Power Button (CM) [PWRB]
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled

serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
parport: PnPBIOS parport detected.
parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE]
parport0: Printer, HEWLETT-PACKARD DESKJET 710C
lp0: using parport0 (interrupt-driven).

Strangely, lp prints the same message, then the printer is found by
parport. Maybe I should disable PNP in the kernel?

PNP seems to pick up the printer alright.  What does your CUPS log
show?  You may need to change its setting to get a more verbose
output.

Gah! Thanks. The log showed me that I was missing foomatic.
I'm pretty sure I made the same mistake last time I was setting up
printing, and I will again if it isn't documented better. Looks like
apart from the logs the only place foomatic is mentioned is in the
actual ppd file :(
