HPLIP

Officejet 710 parallel probe works only once after printer power up

Asked by Fergus M

Hi all..

I am trying to install a minimal hplip setup on an openfiler 2.2/rpath linux to allow scanning from an Officejet 710 (parallel port) with no GUI or Printing support required.

hp-check -t output at end of message

# lsmod
lp 9160 0
parport_pc 22724 1
ppdev 6916 0

# ls -l /dev/parport0
crw-rw-rw- 1 lp lp 99, 0 Nov 22 23:26 /dev/parport0

When I cycle the power on the Officejet 710, and then run hp-probe -g -bpar I get the following:

--------------------
| DEVICE DISCOVERY |
--------------------

hp-probe[4080]: debug: {None: (<built-in function gt>, 0)}
hp-probe[4080]: debug: hp:/par/OfficeJet_Series_700?device=/dev/parport0
hp-probe[4080]: debug: Cache miss: officejet_series_700
hp-probe[4080]: debug: Reading file: /usr/share/hplip/data/models/models.dat

 Device URI Model
 ------------------------------------------------- -----------------------
 hp:/par/OfficeJet_Series_700?device=/dev/parport0 HP OfficeJet Series 700

Found 1 printer(s) on the 'par' bus.

However, if I run it a second time, I get this:

--------------------
| DEVICE DISCOVERY |
--------------------

hp-probe[4081]: debug: {None: (<built-in function gt>, 0)}
warning: No devices found on the 'par' bus. If this isn't the result you are expecting,
warning: check to make sure your devices are properly connected and powered on.

Other tools like hp-info and hp-scan similarly will exit with unknown device unless the printer has just been restarted, in which case they seem to acknowledge the device exists, but then fail with Device I/O error (code=12).

Rebooting the PC makes no difference. Having hpssd running or not makes no difference. Also, configuring printer port as EPP instaed of ECP in the BIOS makes no difference either.

Any ideas on why the probe will not work repeatedly?

At this point it doesn't look like your system is configured correctly for using hplip. You are missing a large number of dependency's required to make hplip function correctly. Also we try and get hplip to function on as many linux distro's however we haven't tested on openfiler 2.2/rpath linux so although in theory it should work, I can't say for sure and at this point it's unsupported.

You could try to resolve the dependency problems and you may have better luck.

Sorry I couldn't help more.

Hi... I will look into the missing deps further, but in the meantime.. I recompiled with more debugging info to examine the source of the error, and I found the following:

The first time hp-probe runs, the Device ID info seems to come back successfully from hpmud.c as evidenced from the debug log:

Nov 24 23:28:17 linuxbox python: io/hpmud/hpmud.c 526: [8237] hpmud_probe_devices() bus=2
Nov 24 23:28:17 linuxbox kernel: ppdev0: registered pardevice
Nov 24 23:28:17 linuxbox python: io/hpmud/pp.c 590: claimed pp fd=3
Nov 24 23:28:17 linuxbox python: io/hpmud/pp.c 639: read actual device_id successfully fd=3 len=96
Nov 24 23:28:17 linuxbox python: io/hpmud/pp.c 611: released pp fd=3
Nov 24 23:28:17 linuxbox kernel: ppdev0: unregistered pardevice
Nov 24 23:28:18 linuxbox python: io/hpmud/hpmud.c 341: [8237] hpmud_exit()

But then on the second attempt, this happens:

Nov 25 00:08:15 linuxbox python: io/hpmud/hpmud.c 336: [16655] hpmud_init()
Nov 25 00:08:16 linuxbox python: io/hpmud/hpmud.c 526: [16655] hpmud_probe_devices() bus=2
Nov 25 00:08:16 linuxbox python: io/hpmud/pp.c 594: claimed pp fd=3
Nov 25 00:08:16 linuxbox kernel: ppdev0: registered pardevice
Nov 25 00:08:16 linuxbox python: ParDevice::nibble_read failed: Input/output error
Nov 25 00:08:16 linuxbox python: io/hpmud/pp.c 643: read actual device_id successfully fd=3 len=0
Nov 25 00:08:16 linuxbox python: io/hpmud/pp.c 615: released pp fd=3
Nov 25 00:08:16 linuxbox python: hp-probe[16655]: warning: No devices found on the 'par' bus. If this isn't the result you are expecting,
Nov 25 00:08:16 linuxbox python: hp-probe[16655]: warning: check to make sure your devices are properly connected and powered on.
Nov 25 00:08:16 linuxbox python: io/hpmud/hpmud.c 341: [16655] hpmud_exit()
Nov 25 00:08:16 linuxbox kernel: ppdev0: unregistered pardevice

This time, the returned device id string is length 0 rather than 96. This is actually because nibble_read gets an input/output error on the IEEE1284_MODE_NIBBLE ioctl call to pprev. This seems to be due to -1 being returned by the parport_negotiate function in ieee1284.c in the parport driver, which imples a timeout waiting for a response for the device ID from the printer.

Does this throw any more light on things? I can't really see how any of the mising dependencies would affect a problem like this within the ppdev module.. but I'm open to suggestions.

Lets remove hp-probe from the test. Does the "hp" backend discovery work repeatedly? Run the following command.

$ /usr/lib/cups/backend/hp

You should see the hp:/par/... URI everytime.

Same thing. Restart machine.. restart printer.. then:

$ /usr/lib/cups/backend/hp
direct hp:/par/OfficeJet_Series_700?device=/dev/parport0 "HP OfficeJet Series 700" "HP OfficeJet Series 700 LPT parport0 HPLIP" "MFG:Hewlett-Packard;MDL:OfficeJet Series 700;CMD:MLC,PCL,PML;CLASS:PRINTER;REV:4.00c;STATUS:000;"
$ /usr/lib/cups/backend/hp
direct hp "Unknown" "HP Printer (HPLIP)"

The debug log for the first attempt shows:

Nov 26 18:12:14 linuxbox hp: io/hpmud/hpmud.c 336: [2635] hpmud_init()
Nov 26 18:12:14 linuxbox hp: io/hpmud/hpmud.c 526: [2635] hpmud_probe_devices() bus=3

Nov 26 18:12:14 linuxbox kernel: ppdev0: unregistered pardevice

And the second time:

Nov 26 18:12:26 linuxbox hp: io/hpmud/hpmud.c 336: [2636] hpmud_init()
Nov 26 18:12:26 linuxbox hp: io/hpmud/hpmud.c 526: [2636] hpmud_probe_devices() bus=3

Ok now I understand the syslog "ParDevice" message. You enabled the old message in pp.c.

This is helpful, but sorry I have no answer to your problem. Apparently this is a ppdev/parport issue with your hardware. Ppdev cannot negotiate nibble mode for device-id after the second probe.

Thanks for the response. I'm thinking this much be something to do with the printer or cable. I installed the printer and cable on a completely different machine running Fedora Core 6, and got exactly the same behavior (detects first time only, works again only after cycling power on the printer).

The thing is, scanning works with the printer and cable when running with a Windows machine.

Here's the hp-check output for the other machine:

Are you able to use the cups parallel backend to print okay?

Hi.. cups was also failing once a print job was started, with 'restarting in 30 seconds' status messages.
I also noted I could repeatedly print pages after restarting the printer by using echo -en '\rtest\r\f' >/dev/lp0
until a did a probe for the device. After getting the initial successful probe response, further attempts to echo to /dev/lp0 failed, and the error log showed a kernel: lp0 offline message.

Then I took a closer look at the parallel cable and found on the printer (centronics) end, some dirt had got trapped on the contacts within the socket on the printer. After cleaning this, the printer now successfully responds to probes every time, and printing via cups is working fine.

Unfortunately the scanning still isn't working though.. I am getting a Device busy message from hp-scan, or Device I/O Errors from scanimage. However, I am going to post this as a different question.
