Hi,

We recently upgraded to the 18.04 LTS running KDE 5.14. We are no longer able to print using the HPLIP driver provided by HP to our HP LaserJet Pro MFP M127fw plugged into the USB port. This driver was previously working fine under 16.04 LTS. Now when we try to print the printer does not respond. We tried updating the HP Toolbox and driver manually using the RUN scripts and TAR files provided on HP's website. These scripts failed to complete due to missing and/or broken dependencies. The script identifies Ubuntu 18.04 as supported but says Neon is "unsupported". We purged the old hplip package, installed the current hplip, then reinstalled the driver using the "Print" tool. This has not worked. Please help!!

Thank you!

Hi there. There seems to be precious little info about printing problems in 18.04. In 16.04 my Canon MX922 would print sheet paper just fine but refused to print on CD/DVD disks. Searching and finding no answers I bought the TurboPrint utility which would print on CD/DVD media. I have been suspect since then that the CUPS + Gutenprint driver was defective. Now, after upgrading Neon to 18.04 my two desktop PCs refuse to print on sheet paper as well. The print queues report the jobs. The printer panel lights up so it knows there is a print job waiting - but it never prints. Just like the CD/DVD print jobs would do under 16.04. Since the TurboPrint utility continues to work I will be able to use that for both sheet paper and disk media. All I need to do now is buy an additional copy for the second PC.

My take on this is that the CUPS + Gutenprint driver is broken for Canon AiO printers. Is it only in KDE Neon? I don't know. And now it appears that HP printer drivers are broken too.

Sorry I couldn't help you. Posting here may raise the issue for more eyeballs to see. There doesn't seem to be a good forum for printer specific problem reports. And TurboPrint is the only work around I have found.

Best,

Well, I found the fix for Canon!

Here are the two steps that corrected my printing as well as others on the Ubuntu forum' The iccprofiles folder existed but wasn't populated. After running the following two commands the folder was populated with some files, presumably icc profiles.

sudo rmdir /usr/share/ghostscript/9.25/iccprofiles
sudo apt-get install --reinstall libgs9-common

I re-created the printer using the Connections 'IPP network printer via DNS-SD'
Selected the CUPS+Gutenprint driver.

It worked for sheet paper but still NOT for CD/DVD media printing. Still need TurboPrint for that.
