Hi,

Debian 11 testing with printer EPSON ET-4750. The printer is already on. Now I switch on my computer. Cups (localhost:631) does not find the printer.

================================================================ Stop and start ipp-usb (and delete log-files). The computer is still on. Now I switch off and on my printer. Now Cups has found my printer.

Maybe you can give me a hint what is going wrong on my computer.

Thanks heiner

Do you have proprietary Epson drivers installed?

ghost commented 3 years ago

Yes, but I purged them after ipp-usb was installed automatically by debian. (apt-get purge printer-driver-escpr)

alexpevzner commented 3 years ago

Hi!

Looks that somebody (CUPS?) steals and reconfigures the device, which causes device to hangup in the middle of conversation.

I have implemented some countermeasures against situations like this. Could you please rebuild ipp-usb and retest?

zdohnal commented 3 years ago

Hi @alexpevzner,

there is a automatic usb installer within system-config-printer-udev, which tries to install/remove print queue for USB printer. I'll try to change its udev rule to ignore 7/1/4 interfaces.

Hi @heiner99, please check whether you have the package above installed in Debian, that could be a service which meddles with ipp-usb.

ghost commented 3 years ago

No change after installation: apt-get install system-config-printer apt-get install system-config-printer-udev

With the latest version of ipp-usb: Endless loop

Hi @zdohnal,

this is not enough to simple ignore 7/1/4 interfaces, because the same interface may implement, for example. 7/1/4 and 7/1/2 protocols, depending on its alt setting, as with this printer, and this is very common for many devices.

The situation becomes even more complex, because there are devices, that advertises 7/1/4 interfaces, but IPP-over-USB actually doesn't work (for now I know only one of them, HP Laser MFP 135a see https://github.com/alexpevzner/sane-airscan/issues/68 for details)

ipp-usb blacklists such a devices, in a hope they will be handled by somebody else (and in order not to interfere with this "somebody else"), but if this list of exceptions will grow, it would be nice to find a way to share it between ipp-usb and udev

alexpevzner commented 3 years ago

@heiner99,

if you restart failed ipp-usb, does work after that?

ghost commented 3 years ago

Same behaviour. I am going to install now a new fresh Debian 11 Testing on my PC. Maybe my current installtion is broken. I will report tomorrow.

alexpevzner commented 3 years ago

Installation is actually very simple, there is nothing to break.

Is my understanding correct, that latest "official" release doesn't work if system boots when printer is already on, while latest patched version doesn't work at all?

ghost commented 3 years ago

The latest patch does not work if printer is already on. If I switched printer off and on, cups will find the printer:

@heiner99,

please, try to rename /usr/lib/udev/rules.d/71-ipp-usb.rules into /usr/lib/udev/rules.d/69-ipp-usb.rules

It will cause ipp-usb to start before /usr/lib/udev/rules.d/70-printers.rules will be executed, which might help.

ghost commented 3 years ago

I don't have .../70-printer.rules on my PC, maybe because I purged system-printer-config

ghost commented 3 years ago

Yesterday I took another PC for testing and everything was fine. The difference was ipp-usb 0.9.13.

So I downloaded 0.9.13 from github and compiled it. I got one compile error (go version go1.15.5 linux/amd64): ./usbio_libusb.go:64:43: cannot use int32(err) (type int32) as type _Ctype_int in argument to _Cfunc_libusb_strerror So I replace line 64 with: return "dummy-error" // C.GoString(C.libusb_strerror(int32(err))) Now I compiled it without errors.

Cups was able to find my printer and printing was ok: I hope this will help you.

Only for your information:

The first version which does not run OK on my PC is the version from 3.September: ipp-usb-14bdcdbfb15ca3bcb0c1a9ea15c3b25d1f6635c5.zip

alexpevzner commented 3 years ago

This is vary interesting observation, thank you!

May I ask you to comment line 533 in the usbtransport.go in the latest version:

err = conn.iface.SoftReset()

and retest.

ghost commented 3 years ago

Latest version from github with comment line 533 works fine on my PC. Cups finds the printer and printing is ok. Thanks you, Good work.

Only for your information: Scanning with sane-airscan works. Scanning with libsane1: failed to open device: escl:http://127.0.0.1:60000:out of memory

zdohnal commented 3 years ago

@alexpevzner thank you for the info! Then the moving ipp-usb rule before system-config-printer-udev rule is the most sensible thing to do right now. If ipp-usb doesn't take care of the device, then s-c-p-udev can get a shot... it would be nice to have a aggregated application for USB printers, which will first try IPP-over-USB solution and then printer application if the former fails.

@heiner99 escl comes from sane-backends project, so if you are willing, please report the issue you see there.

alexpevzner commented 3 years ago

@zdohnal,

@heiner99 made a very good observation, that this problem was introduced in the ipp-usb 0.99.14, while 0.99.13 works well with his device. It helped me to quickly identify the root cause of this problem, so expect 0.99.15 to be released soon with the appropriate fixes.

Out of memory bug in the sane-escl is probably fixed (at least, I've already seen it reported), but logistics of sane-backends package into distros is very slow, so nobody knows when this fix will reach your distro; sane-airscan never had such a problem.

ghost commented 3 years ago

To be more precise:

2: Version 0.9.13 Cups finds the printer and printing is ok. Scanning with sane-airscan works. Scanning with libsane1 works.

3: Version 0.9.14 (and printer is switched off and on) Cups finds the printer and printing is ok. Scanning with sane-airscan works. Scanning with libsane1 works.

alexpevzner commented 3 years ago

Hi,

I've updated the sources to include the fix.

please, retest the latest github version, and if everything is OK, I'll release ot as 0.9.15

Fixed in 0.99.15

Regarding out of memory error with libsabe1, this is sane-escl bug. As far as I remember (from reading sane-devel@alioth-lists.debian.net mail list), this bug already known and fixed, but logistics of sane-backends to most distros is very slow, so most likely the fix has not yet reached your distro,
