samsung SCX-4521F multi function problem with cups

[beerstein]

Hello all:
I saw the many posts on all kind of cups problems. So far I was lucky with cups
until I tried to hook it to a samsung multi function printer.

cups 1.311 is installed and works
gutenprint and foomatic-rip is installed onboot but I only can see the gutenprint printers listed.
I can not see any foomatic entries?
USB port works

http://localhost:631
admin..  even sees the printer
but when it comes to slect the .ppd I can not see any foomatic related pdd?
therefore I downloaded several ppd for this printer and put them into /etc/cups/ppd
and because I could not find a ppd in that list I selected one of these ppd files and installed.

when trying to print a test page:
"/usr/local/lib/cups/filter/foomatic-rip failed" error message shows up

Can somebody please help?

Thank you

Did you try setting the log level to dubug in cupsd.conf, restarting cups and trying again - the error messages often help track down the problem

[beerstein]

Thank you for this - I will look at this and post the results. What does not make sense to me is, that I see
the printers from the gutenprint.tcz but not from the foomatic-rip.tcz do I have to start the foomatic thing?
The .ppd files come from gutenprint and foomatic? Is this correct?
The .ppd files from gutenprint are in /etc/cups/ppd ?
Where do you think, are the foomatic .ppd files?

Where do you think, are the foomatic .ppd files?

As far as I know, you need to find your own, they are not supplied in the cups source tarball

therefore I downloaded several ppd for this printer and put them into /etc/cups/ppd

Put the ppd in another directory.

When you install, cups will put it in /etc/cups/ppd.


You obviously need the correct driver to start with.

from the foomatic info tab
Comments:       the foomatic-rip filter is used by some printer driver packages
                requires libgs.tcz

libgs.tcz contains:
/usr/local/lib/libgs.so.9
/usr/local/lib/libgs.so
/usr/local/lib/libgs.so.9.00

however foomatic depends on libgs_ps which contains:
/usr/local/lib/libgs.so.8
/usr/local/lib/libgs.so
/usr/local/lib/libgs.so.8.71

These cannot co-exist, can they?

[curaga]

Usually they can, unless you want to compile. Apps usually want so.X instead of .so.

[Rich]

Hi curaga
I see, so even though libgs.tcz is not included as a dependency beerstein should install it.

[Juanito]

I have a feeling there are a couple of choices to get foomatic-rip to work, either:

1. load libgs_ps and not libgs
or
2. load libgs and ghostscript_common

As a quick and dirty test, you could ensure libgs.so -> libgs.so.8.71

Hi: Thank you so much for the excellent help.

I changed the "info" to "debug" in /usr/local/etc/cups/cupsd.conf

then I tried to print via the USB port. (testpage)
Here is the error log - only ths part I think is relevant.

================================================
I am using a .ppd which works on the same computer/printer but in Suse 9.3
I will study your posts and report more.

thanks again

What does this give:

Code: [Select]

$ ldd /usr/local/lib/cups/filter/foomatic-rip

[beerstein]

this is what I got:

$ ldd /usr/local/lib/cups/filter/foomatic-rip
linux-gate.so.1 => (0xb77cd000)
libgs.so.8 => /usr/local/lib/libgs.so.8 (0xb7500000)
libm.so.6 => /lib/libm.so.6 (0xb74da000)
libc.so.6 => /lib/libc.so.6 (0xb7397000)
libdl.so.2 => /lib/libdl.so.2 (0xb7393000)
libpthread.so.0 0> /lib/libpthread.so.0 (0xb737b000)
/lib/ld-linux.so.2 (0xb77ce000)

This is the .ppd file recommendet for this printer:
Samsung-ML-4500-gdi.ppd
Oi downloaded it from the website recommended by:SamK

[Juanito]

That looks like it's using libgs_ps rather than libgs. Do you have ghostscript_common loaded?

If you try to execute foomatic-rip like this, what do you get:

Code: [Select]

/usr/local/lib/cups/filter/foomatic-rip --help

[SamK]

I am uncertain whether any of the following is relevant to your circumstances as I use CUPS 1.4.5 rather than 1.3.11.  I certainly do not wish to intrude on any of the advice you are receiving from others.

When using foomatic-rip PPD files, rather than looking for the leanest installation, I prefer a compromise that produces the fewest problems with the equipment here.  The approach adopted is to load:
* CUPS
* foomatic-rip
* ghostscript
* ghostscript-common
* poppler-bin

When using foomatic-rip, my experience is that issues might be multi-layered.  It is possible that overcoming your present difficulty may uncover an unrelated one.  Here's hoping you are lucky and this is not the case for you.
