I basically do the same in Fedora - reverting models.dat to its state in 3.20.5, because I don't have resource to actually test.

[Bug 1883898] Re: version 3.20.6 turns off plugin requirement for most printers
Hi Shivani, I'm sorry I don't have such a list. Did you have such a list when you removed the dependency on plugin for other models in 3.20.6? I base my request (revert all plugin dependency made in 3.20.6) upon the following logic: - when model support was added it was tested by HPLIP project owners - when user had a plugin problem with a model (the model needed a plugin although models.dat says it doesn't), he reached HPLIP project owners with the issue and they updated models.dat so based on the prerequisites it doesn't make sense to remove dependency on plugin for models, unless you have a list of devices which you tested and actually don't need a plugin but they are noted as they need a plugin. Wouldn't it make sense to revert the 'plugin state' to the state before 3.20.6, depending on the presumption 'the previous state was tested' is true? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883898 Title: version 3.20.6 turns off plugin requirement for most printers To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/1883898/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

One concrete example: `drv:///hpcups.drv/hp- laserjet_professional_p1107.ppd` In 3.20.5, in hpcups.drv, it had as NickName: "HP LaserJet Professional p1107, hpcups $Version, requires proprietary plugin" … this was changed in 3.20.6 to: "HP LaserJet Professional p1107, hpcups $Version" … and unchanged in 3.20.9.

Hi Shivani, version 3.20.9 fixed plugin plugin requirement for several models, but other models stayed with the situation from 3.20.6. And there are several models which have 'plugin-reason=65' (meaning it needs a plugin for printing and scanning), but have 'plugin=0' (means it doesn't need a plugin).

Hi Shivani, thank you for looking into the issue! > Could you please provide the printer model name you are using? HP LaserJet M1536dnf MFP > HPLIP does not need to install plugin in order to print. It only requires plugin in order to > scan. Unfortunately, it is not true for several devices, e.g.: hp laserjet cp 1025nw hp laserjet professional p 1102w Their PDL is zjstream, which is supported only by binary blob downloaded via hp-plugin. > Previously, few entities in models.dat had remained as plugin=1 , which has > been removed in > 3.20.6 release. Actually, 'plugin=1' doesn't mean the plugin is needed for printing, but it means whether it is needed or not. The reason why the plugin is needed is covered by 'plugin-reason' (e.g. plugin-reason=64 means the plugin is needed for scanning). So when all 'plugin=1' entries were removed, all those devices think they don't need a plugin (for printing, or scanning, or both) and fail to print/scan anything if the plugin wasn't installed previously (common use case when installing a printer on freshly installed OS). If I look into current upstream models.dat, it seems only scanjet models are marked as they need plugin. Multi-function devices are not taken into account. Ad previous 'plugin=0/1' settings - I'm not sure how many HP devices you have at hand for testing, but at least when I look into scan/sane/hpaio.c: if ((ma.scantype == HPMUD_SCANTYPE_MARVELL) || (ma.scantype == HPMUD_SCANTYPE_MARVELL2)) return marvell_open(devicename, pHandle); if (ma.scantype == HPMUD_SCANTYPE_SOAP) return soap_open(devicename, pHandle); if (ma.scantype == HPMUD_SCANTYPE_SOAPHT) return soapht_open(devicename, pHandle); if (ma.scantype == HPMUD_SCANTYPE_LEDM) return ledm_open(devicename, pHandle); if ((ma.scantype == HPMUD_SCANTYPE_SCL) || (ma.scantype == HPMUD_SCANTYPE_SCL_DUPLEX) ||(ma.scantype == HPMUD_SCANTYPE_PML)) return sclpml_open(devicename, pHandle); if (ma.scantype == HPMUD_SCANTYPE_ESCL) return escl_open(devicename, pHandle); if (ma.scantype == HPMUD_SCANTYPE_ORBLITE) return orblite_open(devicename, pHandle); else return SANE_STATUS_UNSUPPORTED; all device types except for SCL and PML call bb_load() function, which loads symbols from binary plugins downloaded via hp-plugin. To sum it up, I would say most devices which are able to scan and didn't have 'plugin=1' and 'plugin-reason=64' had bad entries in models.dat and supposed to require a binary plugin for scanning. > Also plugin has nothing to do with python version. It will work on python3 as well. I wasn't the one who thought it is a python issue. > Please install plugin via , > $sh hplip-3.20.6.plugin.run This will certainly help, but you are missing the point. Before hplip-3.20.6, hp-setup (with models.dat help) was able to install the plugin automatically, when it recognized that found device needs it. models.dat is used as a database about device features, including plugin. After hplip-3.20.6, models.dat lost info for several models regarding plugin, making them unusable unless you manually install the plugin. IMO making a device work, which your suggestion does, is quite different from 'making a device work in user-friendly way', which hp-setup offered (for those devices, which plugin/plugin-reason were set correctly) before version 3.20.6 and which should be preferred for a long-term solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883898 Title: version 3.20.6 turns off plugin requirement for most printers To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/1883898/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1883898] Re: version 3.20.6 turns off plugin requirement for most printers
The bug report has an upstream task, so the HPLIP developers at HP should be aware. Seems that the main (free software) part of HPLIP which comes packaged with the Linux distributions has no problem with Python 3 but the proprietary plugin which one has to install separately for certain devices requires Python 2. Newer distro versions, especially also Ubuntu 20.04 LTS have dropped Python 2 completely in favor of Python 3, as nowadays practically all important free software projects work with Python 3. To the HPLIP developers at HP, can you make sure that the plugin works also on systems with only Python 3 and no Python 2 installed? On Ubuntu 20.04 LTS and many other newer Linux distributions Python 2 got removed. In many cases, especially on printers which need the plug-in only for scanning one can go a driverless way without HPLIP or anything proprietary needed. If you run the utility driverless on the command line and an entry corresponding to your printer gets listed, it should work driverless. Also if system-config-printer lists your device under the discovered network printers (independent whether it is connected by USB or network, the driverless printing/scanning framework emulates a network printer if the device is connected to USB) with an entry with "driverless" under the connection types, you can do driverless printing. SANE frontends like simple-scan should list your printer, too. Make sure to select an entry which contains "eSCL". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883898 Title: version 3.20.6 turns off plugin requirement for most printers To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/1883898/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The issue which is affecting all flavours of Ubuntu 20.04LTS and HPLIP is already known.

[Bug 1883898] Re: version 3.20.6 turns off plugin requirement for most printers
Hi Sebastien,
as I wrote in the previous comment, I filed the issue for Ubuntu for the
future, because it seems new hplip version hasn't arrived yet.
I'm able to reproduce the issue with my MFD device - HP LaserJet m1536 -
with scanning. According of hpaio code, most devices are using a plugin
for scanning.
The basic reproducer is (after you install hplip-3.20.6):
Prereq:
- has an OS which haven't had HP plugin installed before ('hp-plugin' wasn't
run successfully)
- has a device which needs HP plugin for printing or scanning or for both
- printing and scanning needs to be done via HPLIP, not via any driverless
solutions (print queue device uri needs to start with 'hp://', scanner device
uri with 'hpaio://')
Steps to reproduce for printing (if the device needs HP plugin for printing):
1) install the print queue via hp-setup
2) try to print
Actual result:
Printing fails due missing plugin
Expected result:
Printing goes well
Steps to reproduce for scanning (if the device needs HP plugin for scanning):
1) find out your scanner device uri with:
$ scanimage -L
2) take hpaio:// uri from previous uri and use scanimage to scan:
$ scanimage -d >out.pnm
Actual results:
Scanning fails with Device I/O.
Expected results:
Scanning works.

At a minimum, we need: 1. The specific steps or actions you took that caused you to encounter the problem. 2. The behavior you expected. 3. The behavior you actually encountered (in as much detail as possible).

I added that affects Ubuntu as well even when they haven't got 3.20.6 in their repos yet, because it is just matter of time they will have and the issue will affect them too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883898 Title: version 3.20.6 turns off plugin requirement for most printers To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/1883898/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
