Re: HP 712C Problems

Oh and get this, whenever I print something and then go to http://localhost:631 and look around my printer, it says that it completed all of the jobs that it didnt. Like:

MyPrinter-170 Test Page guest 18k Unknown completed at
Sun Jun 25 17:55:52 2006

But nothing printed so how can it be competed...

Re: HP 712C Problems

Any chance you could post what "this" was? How did you get the problem sorted? Having various cups-related printing problems with Dapper, and any pointers would be helpful.

Cheers.

Re: HP 712C Problems

Lol sorry, I forgot. Ok well my system sees a few different printers when turned on, for some reason it sees a cannon and and epson (even though I dont have these) at two of the parallel ports...then it sees a HP 710C at:

hp:/par/DESKJET_710C?device=/dev/parport0 <- URI

and then of course lp0.

So when I first tried to get everything working I use lp0, this is where I got the forementioned problems. However if I used the hp:/par...etc... location it works. So essentially I deleted my old printer configured at lp0 and just chose the hp:/par/De...etc... location instead. No idea why this works but hey I dont know why most stuff works :-)

Re: HP 712C Problems

Oh phoey I broke it again :-/

Ah well now the thing is back to the way it was before (on lp0) and it isnt seeing that weird URI that worked...soo I looked in the cups error log and I keep getting all these unathorized warnings...but I changed the permissions on lp0 so that everyone has all three, and now that I think of it I remember getting this unathorized stuff since the beginning...??

heres my error_log for cups:

Code:

note that this is just the most recent one (Ive been resetting cups alot trying to get it to work so I havent been able to get a complete log..._

if anyone has any suggestions please tell :-)

Re: HP 712C Problems

I have the same problem with my old HP 820Cxi.
I solved this problem editing the file /etc/pnm2ppa.conf

Here is what I did:
After:
# Sample configuration file
#
# This file will be automatically read upon startup if it is placed in
# /etc/pnm2ppa.conf
#
# uncomment entries by removing "#" to activate them.
#
#-----------set the printer model---------------------------
# The printer model will normally be set by a -v <model> command
# line argument. Otherwise, if not set in the configuration file
# it defaults to the 710/720 series. Remove/comment out the line
# "version 0" below to get the default choice.
#
# If there is more than one "version" entry activated, the last one
# will be used. The printer version can also be set with the command line
# option e.g., "-v 720".

version
#version 720 # 710, 712, 722 also acceptable
#version 820
#version 1000

Before:
# Sample configuration file
#
# This file will be automatically read upon startup if it is placed in
# /etc/pnm2ppa.conf
#
# uncomment entries by removing "#" to activate them.
#
#-----------set the printer model---------------------------
# The printer model will normally be set by a -v <model> command
# line argument. Otherwise, if not set in the configuration file
# it defaults to the 710/720 series. Remove/comment out the line
# "version 0" below to get the default choice.
#
# If there is more than one "version" entry activated, the last one
# will be used. The printer version can also be set with the command line
# option e.g., "-v 720".

version 710
#version 720 # 710, 712, 722 also acceptable
#version 820
#version 1000

I jut add the number 710 on the version. And my printer works !!!
I hope it can help you.

Hugs !

Re: HP 712C Problems

Lol yea I've tried putting in every version in that config file :-/ with and without the c (so like 712 and 712c) and none of them work...lol...

**Phalco77** · Jun 29, 2006, 07:26 AM

Re: HP 712C Problems

Adding the number 710 makes my printer works, but I had problems with adobe acrobat. But I could print a test page on Cups config and a web page using firefox.
The number 710 it is not the number of you printer. It is the number of the version config file, or the version of the CUPS (I think. But I'm sure that it isn't the number of you printer). So, don't add the letter c !!!
Hugs.

Re: HP 712C Problems

Alright well I set my LogLevel to debug and found only really one error that I thought could be causing the error:

Code:

D [29/Jun/2006:13:57:30 -0400] [Job 227] perl: warning: Setting locale failed.
D [29/Jun/2006:13:57:30 -0400] [Job 227] perl: warning: Please check that your locale settings:

D [29/Jun/2006:13:57:30 -0400] [Job 227] LC_ALL = (unset),
D [29/Jun/2006:13:57:30 -0400] [Job 227] LANG = "en_US"
D [29/Jun/2006:13:57:30 -0400] [Job 227] are supported and installed on your system.
D [29/Jun/2006:13:57:30 -0400] [Job 227] perl: warning: Falling back to the standard locale ("C").

Everything else seems to be ok...

Re: HP 712C Problems

and if anyone knows how to get rid of the
cupsdAuthorize: No authentication data provided.

it would be greatly appreciated.

Re: HP 712C Problems

Alright I figured it out (I hope :-/)

First of all for some reason hplip wasnt starting, so I had to manually start /etc/init.d/hplip
And then a simple unplug replug seems to fix the problem, though I'm not sure if this is necessary and I'll test it on next reboot.
