[01:05] <pragmaticenigma> hey TJ- ... welcome to the party
[01:08] <TJ-> oooo alcolhol!?
[01:10] <pragmaticenigma> not quite
[01:10] <pragmaticenigma> if only your issues for PDF were in Windows... I might have some answers
[01:14] <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
[01:15] <TJ-> Been trying to find some bug reports that might cover this, but in vain so far
[01:22] <pragmaticenigma> I could maybe see how a stretch might happen and even monotone, rotation baffles me,
[01:23] <pragmaticenigma> anychance that there is some sort of Adobe proprietary interpreter in the printer?
[01:24] <TJ-> no, printer is fine from other PCs with apparently identical Xubuntu installs
[01:25] <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.
[01:27] <pragmaticenigma> other computers have same issue with inkscape though?
[01:28] <TJ-> no
[01:29] <pragmaticenigma> so one computer with inkscape cannot print?
[01:29] <pragmaticenigma> or rather prints incorrectly
[01:41] <TJ-> something to do with the CUPS and/or PDF filter version I think
[01:42] <pragmaticenigma> but why would it affect only one machine?
[01:42] <pragmaticenigma> i think i'm missing something
[01:43] <TJ-> as I said, the PDF-1.5 version... maybe that confuses the CUPS filter if it doesn't expect 1.5
[01:45] <pragmaticenigma> right but don't the other machines have the same install/configuration?
[01:46] <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
[01:47] <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
[01:48] <pragmaticenigma> that'd be my guess... you do like to experiment :-)
[01:54] <TJ-> Here's what it does:  https://iam.tj/projects/ubuntu/IMG_20200402_022618.jpg
[01:57] <sarnold> weird
[01:59] <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!
[02:00] <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"
[02:01] <TJ-> he can check the producer and PDF versions for differences from my system's values
[02:02] <lotuspsychje> good morning
[02:02] <TJ-> hi lotuspsychje
[02:02] <lotuspsychje> hey TJ-
[06:11] <lordievader> Good morning
[06:39] <ducasse> good morning
[08:38] <lotuspsychje> !info linux-image-generic bionic
[08:45] <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
[08:46] <cengiz_io> what is !USN
[08:46] <cengiz_io> !usn
[08:47] <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
[08:48] <cengiz_io> it only runs Qt4 frontend that controls a huge team of embedded cards over UARTs
[08:49] <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
[08:55] <lotuspsychje> cengiz_io: even offline, its probably part of a network? always good to keep ubuntu running on supported releases
[09:19] <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*
[09:20] <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.
[09:21] <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..
[09:46] <lotuspsychje> cengiz_io: will that machine get external media plugs?
[10:02] <lotuspsychje> !info linux-image-generic eoan
[10:07] <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
[10:16] <lotuspsychje> cengiz_io: ok, so that sounds like a pretty isolated ubuntu system
[11:04] <cengiz_io> lotuspsychje it is. but there will be future feature develelopments
[11:15] <RikMills> cengiz_io: what are you askign exactly?
[11:16] <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
[11:21] <RikMills> Qt4 is not going to get updates in any release, except in case of very critical CVEs. it is now dead upstream
[11:22] <RikMills> hence why it was removed completely from 20.04
[12:01] <cengiz_io> RikMills yet people are very reluctant despite Qt4 applications work almost perfectly with Qt5
[12:02] <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.
[21:44]  * Aavar is upgrading... could not wait...
