Re: CUPS Zebra EPL2 driver through Iceweasel or Evince
On Fri, Mar 14, 2014 at 10:53 AM, Mark Copper mlcop...@gmail.com wrote: Dear List, What might explain this behavior? A Zebra label printer (GX430t) is configured through CUPS and it is desired to print a PDF file on it. The PDF file was created with the Perl module PDF::API2. The file prints fine from the command line: $lpr -P Zebra_Technologies_ZTC_GX430t file.pdf and it prints fine from within gv. But it does not print from within Evince or, more importantly for our purposes, from the embedded Iceweasel pdf viewer. CUPS logs include the error messages: (/usr/lib/cups/filter/rastertolabel) stopped with status 1. and Job stopped due to filter errors; please consult the error_log file for details. It's probability 0 that someone else has had this exact problem. But I'm wondering if anyone might have some ideas on an approach. Maybe something can be changed in the PDF generation? Maybe something can be changed in the Iceweasel settings? Before I let this go, let me add some data and a word of explanation why I posted here. Printing file.pdf from the Firefox viewer (on a Ubuntu box) fails just as it did with Iceweasel. No surprise there I suppose. Chromium doesn't offer an embedded viewer and my system default pdf viewer is Xpdf. Printing from Xpdf fails, but in a different filter. There are two different offers for printing from the Chrome browser on Debian. The native print option works but is useless to me in that it does not properly size the page. Choosing system print succeeds. So I have 2 different ways to go at present: from Iceweasel, download to gv and print from there and from Chrome viewer printing with system print. This seemed like an appropriate forum for this curiosity since it could as well be a problem with the pdf generation or the pdf viewer as with the CUPS filters. It's a matter of getting independent programs to play nice together (not to mention the many levels of processing within CUPS), I guess. Thanks.

Good question. I went into my Iceweasel Preferences, under Applications, and next to the entry for Portable Document Format (PDF) I see this option chosen: [Preview in Iceweasel] If I change that to this setting: [Use Document Viewer (default)] It then brings up PDFs in a separate Document Viewer window. By the way, I never explicitly changed this to Preview. Before Debian I was using Firefox on Ubuntu, and suddenly one day it started doing the embedded preview.
