piCore 9.0.1 and RPI Zero W

[Rich]

Hi matteo
You saw what Juanito said:

In fact nobody has the password for the piCore submit email, so you’ll need to send it to the main one.

Don't send it to the  picore  address listed here:
http://wiki.tinycorelinux.net/doku.php?id=wiki:creating_extensions#submitting
Send it to the first address shown there.

hplip posted to piCore repos - note that more recent versions require a pre-built libImageProcessor.so, but hplip does not supply one for RPi.

Hi Rich, I misunderstood Juanito's sentence. I sent the e-mail to the main address. Thanks!

Thanks Juanito. I do not understand the consequences of that, but the problem seems to be there since half 2018. Any of these links could help? On Red Hat they suggest to use a --nodeps install option, probably there is a way to configure that after ./configure ....

And probably the issue arises after the 3.18.6 hp version. Could it be worth to remain with the 3.18.6 version that does not need  libImageProcessor.so? Is it worth a try?

I posted hplip-3.18.6 - it printed a test page using an RPi3 running piCore-11.x and an hp officejet 6700.

posted - thanks

note that the md5.txt files are needed.

Also if you wish to have a desktop icon, you need to add a line analogous to:

X-FullPathIcon=/usr/local/share/pixmaps/beaver.png

..to the desktop fie

Thanks Juanito,
in the .tcz.info file, the row:

Code: [Select]

$ sudo /usr/local/etc/inid.d/dbus start

should be:

Code: [Select]

$ sudo /usr/local/etc/init.d/dbus start

By the way, the installation of the HP plugin fails on RPi Zero W, TC 11.x, with the error:

I wonder why HP has to make thing sooo difficult. Is the download failing? Is the firmware a sihpP1005.img file (or similar, it could be downloaded while compiling the foo2xqx driver)?

Hi Juanito

... note that the md5.txt files are needed. ...

Thanks for the heads up. I thought the server scripts would handle that, so I omitted them in my last update. Just went
back and updated them.

[Juanito]

Can you print a test page without the plugin?

[matteo]

No, I cannot. If I add a printer from IP address:631/admin, I could see:

HP LaserJet P1005 (HP LaserJet P1005)
HP LaserJet P1005 USB BC04P65 HPLIP (HP LaserJet P1005)
Serial Port #1

I chose the second entry, then it asks for driver or a ppd file. The suggested driver is "HP LaserJet p1005, hpcups 3.18.6, requires proprietary plugin (en)". The test page does not print (state: stopped "Filter failed").
If I use instead a HP-LaserJet_P1005.ppd file, it is the same. The test page does not print (state: stopped "Filter failed").

Accordingly to foo2xqx installation pages, the HP P1005 is a XQX wire protocol printer that requires the firmware to be downloaded to the printer at each printer power on (orange led flashes, drum rotates). However, I never saw that on Windows 7 or Windows 10; but I remember that behavior on very old HP LaserJet vertically feeded.

The plugin required by "sudo hpsetup -ia" (or by "hp-plugin") is, again, "hplip-3.18.6-plugin.run" and it is not the firmware "sihpP1005.img".

[matteo]

I tried to save locally "hplip-3.18.6-plugin.run" downloaded from the hp-developers website. If feeded into "hp-setup -ia", I get:

Python 2.7 and 3.8 are installed.  The following code seems to fail:

Code: [Select]

def get_distro_name():
    os_name = None
    try:
        import platform
        os_name = platform.dist()[0]

and the call platform.dist() should be deprecated since python2.6.

The file "password.py" contains a function that seems to retrieve the su or sudo password (it listed several distro, but not TC. The file "/tmp/tcloop/hplip/usr/local/share/hplip/base/password.py" is not writeable (it seems located on a read-only filesystem). How could I try to write something in "password.py"? I would like to modify the script and see what happens next.

$ sudo cp /tmp/tcloop/hplip/usr/local/share/hplip/base/password.py /usr/local/share/hplip/base
User @andyj solved his plugin problem by downloading the actual firmware blob somehow.

Hi matteo
As you've already found out, the  squashfs  used for extensions is read only. First replace the symlink in the main
file system with a copy of the actual file:

Code: [Select]

sudo busybox cp /usr/local/share/hplip/base/password.py /usr/local/share/hplip/base/
Then rerun your command to make sure the error changes to:

Code: [Select]

File "/usr/local/share/hplip/base/password.py", line 80, in get_distro_nameIf the path in that error message no longer contains  /tmp/tcloop/hplip, then add your changes to:

Code: [Select]

/usr/local/share/hplip/base/password.py

Hi matteo
I think the binary plugin file you need is  hp_laserjet_p1005.plugin
which is located here:
https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/

I have no idea where it needs to be saved to.
