Locate the sources.list file in the /etc/apt/ directory and replace every instance of the word stretch with the word buster.
To update Raspbian from an older version (for example, Stretch) to the latest (Buster, at the time of writing), you need to edit a few files. To reboot your device, enter: sudo reboot Update Raspberry Pi to Buster from an Older Version of Raspbian Filter also attached to this message.If you want to free up some space on your Raspberry Pi, run the clean command to remove the downloaded. The links in the plugin are no longer valid, but should be fixable by adding "/_Archive/" into the path between "/UnRAID/" and "/CUPS/". Use it for reference only as I doubt it'll work out of the box.
Not sure how much this will help, but have attached a zip of my original CUPS plugin. I got this from "" which contains the source which I built on a Slackware 13.1 system. All I needed - which was the hardest to find - was the canon filter (pstocanonij in my case). I'm interested to know more about what you have in the now converted deb and rpm packages? I found that I didn't need to bother creating or converting a package. For me it gave a much better breakdown of all the steps in a print job and I was able to see where it broke.
Might be worth a go if you've not done so already. I recall having to up the CUPS logging level to debug before I found the root cause. I remember similar when first trying to figure out why my Canon MP610 wouldn't print. You mentioned nothing in the logs indicating a problem. I'm not familiar with cups-pdf, so perhaps you can expand on what you had to do to configure that side of things? Would it be correct to assume that cups-pdf uses its own PPD? If so, then wouldn't it be fair to say that a test to cups-pdf isn't really testing the Canon route in so much as although it'll sanity test the bulk of your CUPS installation, the print job is possibly not going through any number of the steps, filters and PPD's that it needs to when printing to your Canon? I realise you're not getting anything from the Canon in UnRAID at this time. So, getting the printer to work comes first, and sorting out airprint (which hopefully won't be too hard) will come later. The real issue is that my Canon printer doesn't print, which is strange to me since it works without a hitch in my Slackware vbox.
Maybe my subject title was wrong because my CUPS is working when I print to PDF (cups-pdf printer). I still need to turn on the computer if I need to print something, but once I'm able to iron out the Canon/CUPS problem. SABNZBD, Sickbeard, Couchpotato, transmission and mysql for XBMC all run off unRAID. Nowadays I hardly ever have to turn on my computer. I read somewhere that we can do email-to-print using CUPS (send an email to CUPS and it prints the attachments) - that would be handy, I'm sure.īut first I'm more interested to get airprint working. Its true the printer is already shared across the network, but using unRAID as the print server would provide a bit more functionality. What other benefits to hooking up a printer to unraid am I missing? The printer is already connected to the LAN, what benefit is there to connecting it to unraid? I was (very possibly mistakenly) under the impression that the only reason to hook a printer up to unraid was to make a USB only printer accessible to multiple machines on the LAN.
I'm not going to be able to help with the stated problem, but I'm genuinely curious as to what you are trying to accomplish. Installpkg foomatic-filters-4.0.4-i486-1.txz Then based also on other information from all over the interweb, I've installed the following: I'm aware that unRAID is based on an older slackware distribution, so maybe there are some packages that I need to install.Ĭapler's guide was really helpful for getting CUPS set up. I think my unRAID-CUPS installation is good because cups-pdf is working well. CUPS test page printed without any problems.
I think the printer drivers are ok, because I use the same drivers for my Slackware14 vbox. No filter or lib related errors in the error log. Printer just gets stuck in the processing state forever.
The drivers were deb and rpm packages but converted to txz in my virtualbox Slackware 14.0 to convert the package so I was able to install it using installpkg.Įverything looks ok, except I can't print anything. Linux CUPS drivers was downloaded from Canon support site. The printer is connected by LAN and was detected by CUPS when adding the printer. I'm really stuck and I need some help from you Linux gurus out there.ĬUPS installed and Canon MF4720w printer added.
