I found that the usb backend stalled here before actually doing any

that it is being blocked on a status read attempt, though this is only
my current guess.

Here is a workaround:

In printers.conf () you will probably find a line like this:

DeviceURI usb:/dev/ulpt0

change usb: to file:, so that it looks something like this:

DeviceURI file:/dev/ulpt0

Then restart cups. Cups will not read any status information from the
printer, but at least it can print. Be warned about unknown side  
effects. :)

I did this fix and it enabled the local server that has the printer

Basically, I have the same problem reported in the one-message-thread  
Can't print to CUPS from Macintosh.


Does anyone have any ideas? The FreeBSD community has my appreciation  
for all of its help on this matter.


Based on the number of problems associated with this issue (there's  
this thread, the aforementioned Mac thread, and the cups 1.2 - no  
output thread), would it be worthwhile to create a new Port named  
cups-devel (keeping the 1.2.x codebase) and downgrade the existing  
cups to the latest 1.1.x version until the bugs have been ironed out  
on the 1.2.x branch (or at least adding an entry to /usr/ports/ 
UPDATING to warn those updating)? Would 1.2.1 fix these issues (that  
is the current stable version whereas FreeBSD's CUPS is at 1.2.0), or  
perhaps the 1.3svn branch? I am unsure where the current problems lay  
(on the CUPS side, on how it is installed in the FreeBSD environment,  
or on the FreeBSD environment itself). Earlier in this thread, the  
issues were primarily related with permissions (since, it was  
mentioned, CUPS is trying to run with a more reasonable set of  
permissions instead of via 'root'), but now they appear to be  
configuration specific. I am willing to try whatever is proposed to  
help the developers get past these issues.

Hello Rico,

Thank you for your reply. Your workaround may only work until you  
reboot your machine and /dev/unlpt0 is re-permission'd. To make that  
fix more permanent, you will need to add the following to your /etc/ 
devfs.rules file (feel free to modify the 0660 to something more of  
your liking).


[system=10]
add path 'unlpt*' mode 0660 group cups
add path 'ulpt*' mode 0660 group cups

And, add the following to your /etc/rc.conf file.

devfs_system_ruleset=system

These were outlined earlier on in this thread. Do you have other  
computers that network print to your printer (and if so, does network  
printing work for you)?


Thank you for your reply.



Best and kind regards,
Rico

The problem is that read operations on usb printers might just
block/hang with no data from the printer (?). ulpt doesn't have
non-blocking I/O, so I've made a patch that simply times out read
operations, and disables further reads if it detects a blocking/stall
condition. It is possible that this breaks the back-channel, as I'm
unsure if we can expect a printer to send inbound data before we
actually write anything out?

It looks like there are similar problems with other backends? I've only
looked at the usb backend yet.

That works for me with my USB Lexmark E210. (The file:/ URI workaround also

Are you using the foomatic script? I am, with a PPD from

I am not sure, actually (it was so long ago, I do not remember how I
got it working). I installed hpijs and Make and Model mentions
Foomatic/hpijs, so perhaps. I am sorry I could not be of more
assistance with this question.


I'm going to try backing up and blowing away my etc/cups dir, re-
updating
the port, reinstalling foomatic and my ppd, and see if that makes any
difference. I'll post whatever I learn.


Thank you for posting your findings and for your quick reply.


No luck. I basically re-installed everything (including config files and
the foomatic filters) from scratch. I also changed the permissions
on /dev/ulpt0 to be 0664 for root:cups. That prevents the permissions
error, but I still get nothing from the printer. The message that 
comes up

in the cups web interface when I try to print a test page is:

/usr/local/libexec/cups/backend/usb failed

I did get my other printer (on a different machine) working with cups 
1.2.0
by just changing the permissions on the device node. I hadn't ever 
set this

printer up with cups before today, though. It's using gutenprint.



After playing with the permissions on ulpt, I can print a test page, 
though

half of it comes out after I manually feed my printer.

After that half-printed page, anything I try to print after will get 
me a USB

port busy; will retry in 30 seconds... message and it never prints.

My system essentially does the same thing (the 30 second message that 
is). After changing my  LogLevel and killing and resubmitting a test 
page, here is my error_log file. Does anyone else have any idea what I 
can try next? Everyone on this list has been wonderful with this thread. 
Thanks again.




I'm not seeing any errors in the log - assuming that the section that 
contains the job you mention starts at 19:29:47 on Jun 27th. I see job 9 
start and I see job 9 canceled but I don't see any errors in between.


A completely random thing: have you tried using /dev/unltp0 instead of 
/dev/ulpt0? It shows up as USB Printer # (no reset) in the cups web 
interface on my system.

 Check the error log for more verbose messages (located in /var/log/cups/
 or from the cups web interface).

I just discovered the web interface, so I'll keep an eye on it.

  From what I've read while trying to solve my failure is that some of
 the backends/drivers don't work properly with the new cups. We're
 probably dealing with several simultaneous failures that need to be
 worked out.

That's the conclusion I'm coming to as well. My sense so far is that most of 
the issues stem from the new cups trying to do as little as possible as root 
and from other pieces assuming / requiring that they will be run as root. 
Obviously the /dev/ulpt permissions thing is a result of this. Another case 
in point is the cups-pdf backend. It stopped working after the cups upgrade 
until I made it setuid root.

 FWIW, cups is working with an Epson 777 and the gimp-print drivers using
 /dev/unlpt0.  It seems to work as well as it did before once I got the
 permissions issue worked out.

Good deal. My network printers at work are also working since the upgrade, so 
all hope is not lost.

add path 'unlpt*' mode 0660 group cups

Oops, I've had a custom devfs.rules for so long that I forgot that you 
need the following in rc.conf:


devfs_system_ruleset=system

I would also create a new /etc/devfs.rules that only has the three lines 
as shown above since that's pretty close to what mine has. I'm not sure 
what all the hide/unhide stuff in the default rules does. Issuing a 
/etc/rc.d/devfs restart /should/ cause ownership and permissions to 
change - at least it did for me. You can always unplug the USB cable or 
power-cycle the printer to test it.

No luck. I basically re-installed everything (including config files and the 
foomatic filters) from scratch. I also changed the permissions 
on /dev/ulpt0 to be 0664 for root:cups. That prevents the permissions 
error, but I still get nothing from the printer. The message that comes up 
in the cups web interface when I try to print a test page is:

/usr/local/libexec/cups/backend/usb failed

I did get my other printer (on a different machine) working with cups 1.2.0 
by just changing the permissions on the device node. I hadn't ever set this 
printer up with cups before today, though. It's using gutenprint.

After playing with the permissions on ulpt, I can print a test page, though 
half of it comes out after I manually feed my printer. 

After that half-printed page, anything I try to print after will get me a USB 
port busy; will retry in 30 seconds... message and it never prints.

Check the error log for more verbose messages (located in /var/log/cups/ 
or from the cups web interface).


From what I've read while trying to solve my failure is that some of 
the backends/drivers don't work properly with the new cups. We're 
probably dealing with several simultaneous failures that need to be 
worked out.


FWIW, cups is working with an Epson 777 and the gimp-print drivers using 
/dev/unlpt0.  It seems to work as well as it did before once I got the 
permissions issue worked out.

are the permissions on /dev/ulpt0 correct ?

I have no idea what it is supposed to be.
%ls -l /dev/ulpt0
crw-r--r--  1 root  operator0,  68 Jun 25 19:01 /dev/ulpt0


if the printer runs fine as root you know it's likely a
permission-problem

What's the best way to run it as root? When I log into the CUPS  
web interface as root and try to print a test page, it gives me  
the message I posted above. If, as root, I try to print a  
Postscript file via lp, it does nothing.
Thank you all again for your  
assistance.___


I had the same problem. chown ulpt0 to group cups and add group  
write. That will fix it. I added the following to /etc/devfs.rules  
to make the fix permanent:

I did

chgrp cups /dev/ulpt0
chmod g+w /dev/ulpt0



[system=10]
add path 'unlpt*' mode 0660 group cups
add path 'ulpt*' mode 0660 group cups
I did not have a /etc/devfs.rules file, so I copied /etc/defaults/ 
devfs.rules to /etc/devfs.rules and added what you suggested at the  
bottom of it.




Don't forget to restart devfs.

When I do
/etc/rc.d/devfs restart
it seems like nothing happens. So, I rebooted my machine and the  
group was back to operator. What am I doing wrong? Thank you so much  
for your assistance with this.

Micah
