| pragmaticenigma | hey TJ- ... welcome to the party | 01:05 |
|---|---|---|
| TJ- | oooo alcolhol!? | 01:08 |
| pragmaticenigma | not quite | 01:10 |
| pragmaticenigma | if only your issues for PDF were in Windows... I might have some answers | 01:10 |
| TJ- | Been an uphill battle... wasted a day trying to get the printer to print at all... turned out a small pop-rivet had 'popped' out due to heavy handling by the courier and a stepper motor had moved out of place so it couldn't ingest cards. Saw the empty hole, shook the printer, out fell the plastic rivet. Now it prints fine *except* from the one application it needs to, Inkscape. However, | 01:14 |
| TJ- | printing to PDF *then* opening it with Evince (PDF viewer) and then printing it from there works fine! Difference being the former uses cairo library and PDF-1.5, and the latter uses Ghostscript and PDF-1.2 | 01:14 |
| TJ- | Been trying to find some bug reports that might cover this, but in vain so far | 01:15 |
| pragmaticenigma | I could maybe see how a stretch might happen and even monotone, rotation baffles me, | 01:22 |
| pragmaticenigma | anychance that there is some sort of Adobe proprietary interpreter in the printer? | 01:23 |
| TJ- | no, printer is fine from other PCs with apparently identical Xubuntu installs | 01:24 |
| TJ- | I've checked the local user config has nothing set to affect this by printing from another user account. There's something in the CUPS filters I think but, again, cannot figure out where. | 01:25 |
| pragmaticenigma | other computers have same issue with inkscape though? | 01:27 |
| TJ- | no | 01:28 |
| pragmaticenigma | so one computer with inkscape cannot print? | 01:29 |
| pragmaticenigma | or rather prints incorrectly | 01:29 |
| TJ- | something to do with the CUPS and/or PDF filter version I think | 01:41 |
| pragmaticenigma | but why would it affect only one machine? | 01:42 |
| pragmaticenigma | i think i'm missing something | 01:42 |
| TJ- | as I said, the PDF-1.5 version... maybe that confuses the CUPS filter if it doesn't expect 1.5 | 01:43 |
| pragmaticenigma | right but don't the other machines have the same install/configuration? | 01:45 |
| TJ- | I think part of it is the PPD for the printer sets a media type "Card" but for some reason the print dialog in Inkscape doesn't see that one. I set the page size manually to the same 86x54mm but it looks like without the media set to the exact media name it causes some upset | 01:46 |
| TJ- | they do, in principle, but over time maybe something subtle has been changed... or because I do a lot of experimentation on mine maybe I've some package installed that affects this | 01:47 |
| pragmaticenigma | that'd be my guess... you do like to experiment :-) | 01:48 |
| TJ- | Here's what it does: https://iam.tj/projects/ubuntu/IMG_20200402_022618.jpg | 01:54 |
| sarnold | weird | 01:57 |
| pragmaticenigma | me thinking out loud... TJ- you tested this specific printer on other machines? | 01:59 |
| TJ- | pragmaticenigma: correct, and there it prints the same file fine from Inkscape with the same printer driver! | 01:59 |
| TJ- | I'm going to get the apprentice to do some comparisons later today (I'm working through the night but he'll be here in about 5 hours!) | 02:00 |
| pragmaticenigma | Me thinks your machine is "special" | 02:00 |
| TJ- | he can check the producer and PDF versions for differences from my system's values | 02:01 |
| lotuspsychje | good morning | 02:02 |
| TJ- | hi lotuspsychje | 02:02 |
| lotuspsychje | hey TJ- | 02:02 |

| lotuspsychje | !info linux-image-generic bionic | 08:38 |
| ubot5 | linux-image-generic (source: linux-meta): Generic Linux kernel image. In component main, is optional. Version 4.15.0.91.83 (bionic), package size 2 kB, installed size 16 kB | 08:38 |
| lotuspsychje | good morning cengiz_io | 08:45 |
| cengiz_io | hello | 08:45 |
| cengiz_io | good morning to you too lotuspsychje | 08:45 |
| cengiz_io | thanks for your invite | 08:45 |
| lotuspsychje | cengiz_io: i would convince them more with !USN then bugs, cause bugs arise very much, on every release | 08:45 |
| cengiz_io | what is !USN | 08:46 |
| cengiz_io | !usn | 08:46 |
| ubot5 | Please see https://usn.ubuntu.com/ for information about recent Ubuntu security updates. | 08:46 |
| cengiz_io | oh. it's a good start. | 08:47 |
| cengiz_io | thankfully though the device is completely offline. it will be used in intensive care units and there's no connectivity. not even USB | 08:47 |
| lotuspsychje | cengiz_io: that will prove your team, tons of security flaws are risky to keep using 14.04 | 08:47 |
| cengiz_io | it only runs Qt4 frontend that controls a huge team of embedded cards over UARTs | 08:48 |
| cengiz_io | by the way let me introduce myself. I'm an embedded linux developer working for a multibillion dollar company that uses Linux almost everywhere. but mostly custom built stuff with Yocto and Buildroot. x86_64 is very expensive | 08:49 |
| lotuspsychje | cengiz_io: even offline, its probably part of a network? always good to keep ubuntu running on supported releases | 08:55 |
| cengiz_io | sorry my archlinux hanged LOL | 09:19 |
| cengiz_io | lotuspsychje in fact, it won't be connected to any network. except maintenance by field personell | 09:19 |
| cengiz_io | personnel* | 09:19 |
| cengiz_io | lotuspsychje but it will certainly be constantly get updates to userspace frontend application, and I don't want my team to work on an archived OS image that doesn't exist anymore. | 09:20 |
| cengiz_io | I can even imagine requiring a new library that doesn't ship with aptitude and thus we have to install manually created deb packages.. | 09:21 |
| lotuspsychje | cengiz_io: will that machine get external media plugs? | 09:46 |
| lotuspsychje | !info linux-image-generic eoan | 10:02 |
| ubot5 | Package linux-image-generic does not exist in eoan | 10:02 |
| cengiz_io | hello lotuspsychje. currently only sensors via CAT5 cables. they are using custom protocols. but as in media if you mean USB drives and such, no | 10:07 |
| lotuspsychje | cengiz_io: ok, so that sounds like a pretty isolated ubuntu system | 10:16 |
| cengiz_io | lotuspsychje it is. but there will be future feature develelopments | 11:04 |
| RikMills | cengiz_io: what are you askign exactly? | 11:15 |
| lotuspsychje | RikMills: his original question was to convice his team why to upgrade to 18.04 from 14.04 | 11:16 |
| lotuspsychje | with all bugs in between | 11:16 |
| RikMills | Qt4 is not going to get updates in any release, except in case of very critical CVEs. it is now dead upstream | 11:21 |
| RikMills | hence why it was removed completely from 20.04 | 11:22 |
| cengiz_io | RikMills yet people are very reluctant despite Qt4 applications work almost perfectly with Qt5 | 12:01 |
| cengiz_io | (minus the font issue ofc, that's easily fixable by installing cc fonts) | 12:02 |
| cengiz_io | anyway thank you for your assistance. I'll compile my warnings and propose my idea. the rest is up to those decision makers. | 12:02 |
