Unexpected black lines in printouts (HP CP1515n)

mittfh · 04-02-2010, 09:18 AM

Mandriva 2010.0 / HP Color LaserJet CP 1515n

Using HP's own Linux drivers over CUPS or HPLIP.

Whenever I print, black lines occur whenever there's a line break. This doesn't occur with the test page, but with any document printed (text, OpenOffice, webpage, Thunderbird email).

Here are scans (600px high JPEG) of three recent printouts:
Email
Website
Text document
Test Page

Here's the CUPS config:

Description: HP_Color_LaserJet_CP1515n
Location:
Driver: HP Color LaserJet cp1515n pcl3, hpcups 3.9.12 (color)
Connection: hp:/usb/HP_Color_LaserJet_CP1515n?serial=00CNCT8DGHDX
Defaults: job-sheets=none, none media=iso_a4_210x297mm

Does anyone have a clue as to what's going on and how to fix it?

That's pretty strange, check back through your install logs and verify that there were no errors, try printing from another device to that printer. It appears as if its defaulting to black for non specified whitespace. I'd yank everything printing out and purge it and reinstall the drivers, thats pretty messed up.

i have always hated printers until i found this site and followed their instructions to the 'T' http://hplipopensource.com/hplip-web/index.html read 'ALL' instructions and for ubuntu it said stop and reboot before running hp-setup. 3 perfect installs for me. jackb

Righteo, took a while but I've eventually solved the problem.

Uninstalled everything and reinstalled - no change.
Uninstalled everything, downloaded hplip and ran through the setup process.
Even though I'd got libusb-1.0.6 installed, I had to reinstall from source as MDV package doesn't include the libusb-1.0.la file. Libgphoto-devel also had to be installed.
Finally, I get everything set up, although I had to add the printer via cups as hp-setup wouldn't allow me to finish...

Using CUPS' default pcl3 driver, I still got the black lines.
However, changing to the ps driver (which was what hp-setup would have used had it been able to finish) worked (no mysterious black lines) - and oddly enough, even though I had to manually select the ppd from disk, cups now claims it's the recommended driver. Go figure...

Random Speculation: the pcl driver problems might be due to the linux drivers using pcl3, whereas Windoze drivers are typically pcl5 or pcl6. Whereas of course ps is an unchanging standard.

Your analysis sounds reasonable, that is definitely a pretty strange occurrence, but you've found what I normally find... if the printer supports printing direct from PS in *nix use it... it works flawlessly.

same thing happened with me. but i used hp-setup in manual mode by giving my printer ip and it found it and npw everything is back to normal

I recently ran into the same problem. I did nothing except I choose "Modify Printer" from the CUPS web menu. Then I chose the obvious answers. In my case I choose this driver:

Code:

Driver:	HP Color LaserJet cp2025dn hpijs pcl3, 3.10.2 (color, 2-sided printing)

I made sure that my choice was listing "hpijs" first instead of "pcl3". Now all is well. It makes no sense but at least I'm not wasting any more black toner on what was coming to be almost solid black pages!

Perhaps this was due to my Slackware upgrade from 13.0 to 13.1 and thus a CUPS upgrade. I'm really not sure. But at least the fix is easy.

I have had same pain. I healed it in this way:
I removed all printers from CUPS web page and execute

Code:

hp-setup -i -b net
<ENTER>
<ENTER>
...
<ENTER>

That go to CUPS web page and saw (surprise!):
Driver: HP Color LaserJet CP1510 Series Postscript (recommended)
Presto. "Black lines dead baby, black lines dead".
I hope it help somebody.

I have the same printer but using Ubuntu 10.04. After installing using this file http://sourceforge.net/projects/hpli...9.run/download I was able to print text fine. For instance from Writer. However I wasn't able to print a 1.5MB jpg file. The printer said it was low on memory. So I Googled and found a bug report (https://bugs.launchpad.net/ubuntu/+s...ro/+bug/597338) suggesting to use PCL drivers as there may work better. So I changed to the PCL driver (HP Color LaserJet cp1515n pcl3, hpcups 3.10.9) and got the black lines issue.

So, I can print images with the PCL and text with the PS driver (HP Color LaserJet CP1510 Series Postscript (recommended)).

Can anyone tell me how to print images with the recommended PS drivers?

Cheers

Ian
