Title: CUPS without HPLIP for HP printers (SOLVED)
Post by: xyz-worx on January 22, 2012, 12:19:27 PM
Hi all,
the last days I installed CUPS together with hplip-2.7 and the ghostscript package to
get a HP LaserJet 5L running - and it works.
Unfortunately the hplip package is very huge due to the dependency  of python, which I do not need.
Browsing the Wikis and the forum did  show, that it must be possible to use e. g. gutenprint
and/or foomatic-rip instead of hplip. Testing several different combinations (e. g. with cups1311)
I got always the same behaviour:
After I start dbus and cups and type

Code: [Select]
sudo lpinfo -v
I get no information about my LJ5L attached to the parallel port.
If I do the same having hplip installed, one of several other messages is:

Code: [Select]
sudo lpinfo -v
...
direct hp:/par/HP_Laser_Jet5L?device=/dev/parport0
 
My questions are:

best regards

You'd need to check if the kernel parallel port drivers are loaded and the libieee1284 extension might help

Hi Juanito,
thank you for your reply.
I think the parallel port drivers are loaded, because dmesg reports
Code: [Select]
parport0: Printer , Hewlett-Packard  HP LaserJet 5L
ppdev: user-space parallel port driver

So I will check, if libieee1284 will work.

best regards

What does "lsmod" show in terms of parallel port drivers?

Regardless of hplip being loaded or not, lsmod gives the same output:

Code: [Select]
tc@box:~$ lsmod
Module                  Size  Used by    Tainted: G 
nfsd                  162388  8
exportfs                2096  1 nfsd
squashfs               14724  0
scsi_wait_scan           276  0
ppdev                   3732  0
parport_pc             18656  0
parport                18560  2 ppdev,parport_pc
ramzswap               10240  1
loop                    8068  0
dmfe                   11348  0

Installing libieee1284 also does not show a printer on the parallel port via lpinfo.

It's interesting, if someone could setup a non Hewlett Packard printer on the parallel port.

Is there anybody out there?

Hi xyz-worx
For what it is worth, I noticed that  libieee1284  includes a program called  libieee1284_test.
You could try running that and see if it reports anything interesting. You could also try
libieee1284_test  --help    to see if it offers any useful options.

The required parallel port drivers seem to be loaded - what uri are you using in cups for the printer?

The lp module is not listed. 

You might try
Code: [Select]
sudo modprobe lpand test with
Code: [Select]
lsmod | grep lp
It should report something similar to
Code: [Select]
lp                      7454  0
parport                31046  3 parport_pc,ppdev,lp
My preference is to load the lp module before loading any of the printer related extensions.

Thank you all for your support.
That's what I found out:

@Juanito:
As  described in my first post, the uri is
 hp:/par/HP_Laser_Jet5L?device=/dev/parport0

@Rich
With libieee1284 installed I get

Code: [Select]
tc@box:~$ libieee1284_test
Found 3 ports:
  0x278:
  0x378:
  0x3bc:

0x278: inaccessible
0x378: inaccessible
0x3bc: inaccessible

I don't know, what exactly this lib is doing. It reports, that no port is accessable, but on the
other hand, dmesg says
Code: [Select]
...
parport_pc 00:0a: reported by Plug and Play ACPI
parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE,EPP]
Adding 128704k swap on /dev/ramzswap0.  Priority:-1 extents:1 across:128704k SS
parport0: Printer, Hewlett-Packard HP LaserJet 5L
ppdev: user-space parallel port driver
...
So I think there is a port at 0x378 - and it works as soon as hplip is active.

@SamK:
There is definitely no modul 'lp' present and obviously hplip does not need it.
As far as I could see, modprobe is not part of TC. So I will look, where I can find
and install it.

Thanks

It is part of Tinycore. If you enter  ls -l /sbin/modprobe  it should show that it is a link back to
/bin/busybox.

Thank you guys!
The lp module seems to lead me to the solution!  After loading this module, lpinfo
now reports

direct parallel:/dev/lp0

and with this, cups-admin offers the HP LJ5L to install  on this port. What I have to do is
to find a place to invoke the lp module - I'll try in bootlocal.sh.
As soon as it works, I will let you know.

Thanks again!

Finally I got what I wanted.  After inserting  'modprobe lp' to bootlocal.sh the print system
works, only consisting of
CUPS
ghostscript and
ghostscript-commons

The only thing I had to fetch externally was the PPD file for my HP LJ5L.
But for this http://www.openprinting.org (http://www.openprinting.org) has all the information one needs.

By the way, with this compilation of modules - avoiding hplip - I was able to
save more than 19 (unnecessary) MB.
And this keeps my Tiny Core tiny furthermore!

thanx for your support and bye
