CUPS experts?

[Paul Goyette]

I've recently installed cups, and having some difficulty getting it to
work. (I'm pretty sure I'm doing something wrong, but I haven't any
clue on where to look...)

I have manually started cupsd (since there doesn't seem to be any
/etc/rc.d file), and I've also stopped lpd. I used the web admin
interface to add my printer, which shows up in /etc/printcap as

lp|HP DeskJet 6940 series:rm=screamer.whooppee.com:rp=lp:

The pritner admin page shows

Description: HP DeskJet 6940 series
Location:
Driver: HP DeskJet 6940 Foomatic/hpijs (recommended)
(color, 2-sided printing)
Connection: socket://192.168.2.253
Defaults: job-sheets=none, none media=na_letter_8.5x11in
sides=one-sided

I tried to print a document from LibreOffice4, and it appears to submit
the job correctly. Cups seems to acknowledge the job:

...
lp-2 Unknown Withheld 150k Unknown completed at
Sat Jun 28 05:20:13 2014
lp-1 Unknown Withheld 150k Unknown completed at
Sat Jun 28 05:13:11 2014

Yet, nothing is printed on the printer, and a tcpdump shows only an
occassional ipp broadcast 30-second intervals), and a brief snmp
exchange (IP addresses manually editted here for brevity):

server.60709 > printer.snmp:
{ SNMPv1 { GetRequest(28) R=1 25.3.2.1.3.1 } }
printer.snmp > server.60709:
{ SNMPv1 { GetResponse(51) R=1 25.3.2.1.3.1="Deskjet 6940 series" } }
server.60709 > printer.snmp:
{ SNMPv1 { GetNextRequest(27) R=1 43.12.1.1.4 } }
printer.snmp > server.60709:
{ SNMPv1 { GetResponse(34) R=1 43.13.4.1.2.1.1=7 } }
server.60709 > printer.snmp:
{ SNMPv1 { GetRequest(28) R=1 25.3.5.1.2.1 } }
printer.snmp > server.60709:
{ SNMPv1 { GetResponse(33) R=1 25.3.5.1.2.1=00 } }
server.60709 > printer.snmp:
{ SNMPv1 { GetRequest(29) R=1 43.10.2.1.4.1.1 } }
printer.snmp > server.60709:
{ SNMPv1 { GetResponse(35) R=1 43.10.2.1.4.1.1=3307 } }

There is no traffic to the printer socket (port 9100), and nothing
prints.

FWIW, the same results are obtained if using the Cups admin page to
print a TestPage to the printer. A job is created, and is displayed as
Completed yet nothing gets sent to the printer.

Any suggestions?

Paul,

Can you try switching to the hpcups driver rather than the hpijs one?

Paul,

I have installed all of the foomatic filter packages:

# pkg_info -a
foomatic-filters-3.0.2nb10 Spooler-independent PostScript printing filter
foomatic-filters-cups-3.0.2nb2 Foomatic support for CUPS
foomatic-ppds-20070207 Foomatic PPDs collection
foomatic-ppds-cups-20070207nb1 Foomatic PPD collection for CUPS servers

But I don't seem to have any hpcups driver:

# find /usr/pkg/share/foomatic/ -name '*cup*' | wc
0 0 0
#

You need to install print/hplip to obtain the drivers from HP Linux
Imaging and Printing.

Unless you've got PKG_RCD_SCRIPTS set, the rc.d scripts with the
package install into /usr/pkgsrc/share/examples/rc.d. Look for
the rc.d script for cups (and other packages) there. (since I
never remember to set PKG_RCD_SCRIPTS, I end up installing them
manually.)

What happens when you try to send something directly to port
9100?

Have verified that the printer doesn't support either IPP or
LPD directly? If it supports either of those, I would recommend
using those protocols over the TCP stream at port 9100.

It looks like I forgot to mail the list directly when I helped Paul.

He got the printer working. It was a combination of missing CUPS
filters and the outdated IJS driver. Installing print/hpijs fixed
that.

For what its worth, the CUPS project in their documentation recommend
AppSocket/JetDirect (9100/TCP) over LPD and IPP. I too was somewhat
shocked to learn this.
