[01:05] hey TJ- ... welcome to the party [01:08] oooo alcolhol!? [01:10] not quite [01:10] if only your issues for PDF were in Windows... I might have some answers [01:14] 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] 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] Been trying to find some bug reports that might cover this, but in vain so far [01:22] I could maybe see how a stretch might happen and even monotone, rotation baffles me, [01:23] anychance that there is some sort of Adobe proprietary interpreter in the printer? [01:24] no, printer is fine from other PCs with apparently identical Xubuntu installs [01:25] 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] other computers have same issue with inkscape though? [01:28] no [01:29] so one computer with inkscape cannot print? [01:29] or rather prints incorrectly [01:41] something to do with the CUPS and/or PDF filter version I think [01:42] but why would it affect only one machine? [01:42] i think i'm missing something [01:43] as I said, the PDF-1.5 version... maybe that confuses the CUPS filter if it doesn't expect 1.5 [01:45] right but don't the other machines have the same install/configuration? [01:46] 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] 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] that'd be my guess... you do like to experiment :-) [01:54] Here's what it does: https://iam.tj/projects/ubuntu/IMG_20200402_022618.jpg [01:57] weird [01:59] me thinking out loud... TJ- you tested this specific printer on other machines? [01:59] pragmaticenigma: correct, and there it prints the same file fine from Inkscape with the same printer driver! [02:00] 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] Me thinks your machine is "special" [02:01] he can check the producer and PDF versions for differences from my system's values [02:02] good morning [02:02] hi lotuspsychje [02:02] hey TJ- [06:11] Good morning [06:39] good morning === Guest45700 is now known as lordievader [08:38] !info linux-image-generic bionic [08:38] 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 [08:45] good morning cengiz_io [08:45] hello [08:45] good morning to you too lotuspsychje [08:45] thanks for your invite [08:45] cengiz_io: i would convince them more with !USN then bugs, cause bugs arise very much, on every release [08:46] what is !USN [08:46] !usn [08:46] Please see https://usn.ubuntu.com/ for information about recent Ubuntu security updates. [08:47] oh. it's a good start. [08:47] 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] cengiz_io: that will prove your team, tons of security flaws are risky to keep using 14.04 [08:48] it only runs Qt4 frontend that controls a huge team of embedded cards over UARTs [08:49] 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] cengiz_io: even offline, its probably part of a network? always good to keep ubuntu running on supported releases [09:19] sorry my archlinux hanged LOL [09:19] lotuspsychje in fact, it won't be connected to any network. except maintenance by field personell [09:19] personnel* [09:20] 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] 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] cengiz_io: will that machine get external media plugs? [10:02] !info linux-image-generic eoan [10:02] Package linux-image-generic does not exist in eoan [10:07] 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] cengiz_io: ok, so that sounds like a pretty isolated ubuntu system [11:04] lotuspsychje it is. but there will be future feature develelopments [11:15] cengiz_io: what are you askign exactly? [11:16] RikMills: his original question was to convice his team why to upgrade to 18.04 from 14.04 [11:16] with all bugs in between [11:21] Qt4 is not going to get updates in any release, except in case of very critical CVEs. it is now dead upstream [11:22] hence why it was removed completely from 20.04 [12:01] RikMills yet people are very reluctant despite Qt4 applications work almost perfectly with Qt5 [12:02] (minus the font issue ofc, that's easily fixable by installing cc fonts) [12:02] anyway thank you for your assistance. I'll compile my warnings and propose my idea. the rest is up to those decision makers. === lotuspsychje_ is now known as lotuspsychje === kostkon_ is now known as kostkon [21:44] * Aavar is upgrading... could not wait...
