HPLIP on Slackware 15.0

edorig · 03-05-2023, 11:11 AM

I have tried to setup an USB HP Laserjet Professional P1102w printer on Slackware 15.0 32 bit Intel using hp-setup, but everytime I used the program, I obtained an error message saying that no device could be found on port usb:
Using lsusb, I could detect the printer and find its bus and USB id. There were also entries under /sys/bus/usb/devices/1-2/uevent that matched lsusb output, but giving bus id and device id did not help with hp-setup.

Instead, I used directly

Code:

seamonkey http://localhost:631 
hp-plugin

to set up the print queue with hpcups as driver and download the HP proprietary plugin. I could successfully print a test page, and print
as a regular user with the web browser. But hp-setup kept indicating it could not find a printer.
I have found in /var/log/syslog the folllowing entries

Code:

hp-setup: io/hpmud/model.c 532: no HP_LaserJet_Professional_P1102w attributes found in /usr/share/hplip/data/models/models.dat 
Mar  4 17:48:05 sashimi hp-setup: io/hpmud/model.c 543: no HP_LaserJet_Professional_P1102w attributes found in /usr/share/hplip/data/models/unreleased/unreleased.dat 
Mar  4 17:48:05 sashimi hp-setup: io/hpmud/musb.c 2129: ignoring hp:/usb/HP_LaserJet_Professional_P1102w?serial=000000000Q91VDW2SI1c support=0 
Mar  4 17:48:05 sashimi hp-setup: hp-setup[3650]: error: No devices found on bus: usb

The file /usr/share/hplip/data/models/models.dat actually contains an entry

Code:

[hp_laserjet_professional_p1102w]
align-type=0
clean-type=0
color-cal-type=0
copy-type=0
embedded-server-type=0
fax-type=0
fw-download=False
icon=HP_LaserJet_1012.png
io-mfp-mode=6
io-mode=1
io-support=10
job-storage=0
linefeed-cal-type=0
model1=HP LaserJet Professional P1102w Printer
monitor-type=0
panel-check-type=0
pcard-type=0
plugin=1
plugin-reason=1
power-settings=0
pq-diag-type=0
r-type=0

so I don't understand what is the cause of the message in syslog.
The error log for CUPS contains

Code:

DEVICE_URI=usb://HP/LaserJet%20Professional%20P1102w?serial=000000000Q91VDW2SI1c
PID 3396 (/usr/lib/cups/filter/hpcups) exited with no errors.

So it looks like the HPLIP plugin and the driver are correctly configured
by CUPS, but for some reason, the hp-setup and all other HP utilities fail
to detect that.

On Ubuntu 18.04 LTS and Ubuntu 20.04 LTS, the same printer can be configured
with CUPS and a foo2zjs driver or hp-setup -i.

Is there some missing dependency in the HPLIP python code on Slackware 15.0 ?

I have a laserjet P1102 (non wifi) under Slackware 64-current and 64-stable. Working fine here.

I install these printers by providing CUPS the respective PPD from foo2zjs and, next, runnig hp-toolbox as a regular user to install the proprietary plugins.

One problem I found with hplip 3.20.5 is that hplip uses to save the plugin in a wrong directory and then it searches for it in another, so I manually download the respective plugin from https://developershp.com/hp.linux-im...inting/plugins (for downloads). See here more info: https://developershp.com/hp-linux-im...ry_plugin.html.

I have encountered an issue with HPLIP in --Current. It's not a big deal to me, so I haven't pursued it, but, when I try to set up my HP OfficeJet 6960, get the message below. The printer is on the wired network and has a static ip address and is maybe three or four years old.

I mention this simply in case it helps shed light on OP's issue.

Code:

Please enter a name for this print queue (m=use model name:'OfficeJet_6960'*, q=quit) ?y
Using queue name: OfficeJet_6960nt queue (m=use model name:'OfficeJet_6960'*, q=quit) ? 
Locating PPD file... Please wait.
error: No PPD found for model officejet_6960 using old algorithm.
error: Unable to find an appropriate PPD file.

Note that my Slackware is in a VM, but I have successfully set up this same printer in other VMs.

And we have this issue too https://www.linuxquestions.org/quest...re-4175721614/

You have found the cause of the complaints of hp-plugin about the absence of plugin even after a successful download. I suspect that the cause of the messages in the /var/log/syslog is that the model.c is using
a case sensitive search in /usr/share/hplip/data/models/models.dat. On my system, it is possible to print
both as root and as a regular user using CUPS but hp-setup and hp-systray remain unable to detect the HP Printer. So, somehow, the plugin+hpcups is working as expected for CUPS, but HPLIP is unable to detect it.

I have tried the links you provided, but both of them give errors. I'll try to find them in the Wayback Machine to have some backup for the plugin.

I have also downloaded foo2zjs in case the plugin+hpcups method stops working.

This is very similar to my issue with the HP printer. The file models.dat contains an [officejet_6960] entry. Maybe you have some error message in the /var/log/syslog as well.

Since I can print, I considered the issue solved for myself, but HPLIP is clearly buggy.

Yes, the direct link I sent you is not working today. I have googled "hplip plugin" and found this one, which is online right now. Inside it you can download the file/plugins according to your hplip-x.xx version (*-run and *-run.asc files), save them in a directory and point to them when asked by the hp-plugin or hp-toolbox script. See if the link below works for you.

The link works for me, I have downloaded the plugin in case I need to redo the printer installation. There is a SlackBuild
script for an older version than 3.20.5 used in Slackware 15.0 at slackbuilds.org/repository/15.0/system/hplip-plugin. I should be able to adapt it for the more recent plugin.
