When I plug in my printer this shows up in my dmesg:

usb 6-2: new full speed USB device using ohci_hcd and address 9
usb 6-2: New USB device found, idVendor=03f0, idProduct=7d04
usb 6-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 6-2: Product: Deskjet F2100 series
usb 6-2: Manufacturer: HP
usb 6-2: SerialNumber: CN79J4Q56204TK
usb 6-2: configuration #1 chosen from 1 choice
usblp0: USB Bidirectional printer dev 9 if 1 alt 0 proto 2 vid 0x03F0 pid 0x7D04


Instantly after I try to print a test page with CUPS or with hp-tool, I get this in dmesg:
usblp0: removed


With the hp-tool, I can see every status of the printer, eg.: cartridge, printer status, spool status, and the hp-check runs The only thing not working is printing.
The hp-setup tool installs the printer, and the process seems to be correct; only one warning is issued during the installation:
/error: No PPD found for model deskjet_f2100_series. Trying old algorithm...
So it selects the /usr/share/cups/model/HP/hp-laserjet_2100-ps.ppd.gz file by default. I can't do much about it, because there is no ppd file for this type of printer as far as I know, because it supposedly is supported by the hplip package.

Also, the CUPS frontend (http://localhost:631) seems to be in sync with the hp-setup application, because the installed printer shows up in each with the same properties and options.

Also I can tell the printer functions properly (it can print), because I can copy (scan+print) with the button on it (it is an "all-in-one" scanner/printer).

I am in the 'lp' group, but printing doesn't work for root either.

Any suggestion/help would be appreciated!

Little information from CUPS:

And here is the rather long output of hp-check:

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper
dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has
the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

Done.

Please do not post so much detail---I don't know very many people with the patience to read all of that.

My system has drivers for that printer (I'm using CUPS 1.4.2 with HPLIP installed) It offers 2 hpijs drivers, and one hpcups. Curiously, a search of /usr/share shows up something in foomatic, but that does not appear in the options when installing the printer.

/usr/share/ppd/HP/hp-laserjet_2100-ps.ppd.gz

.. is actually from package ' hplip-hpijs-ppds-3.9.xx '
or similar.

Have you looked in /etc/cups/ppd/
for the file hp-laserjet_2100-ps.ppd ?
.....

I have that laserjet 2100 ppd file too and I'm now using it, but I can not print anything. However, I'm not really sure that I need a LaserJet 2100 driver for a DeskJet F2100 scanner/printer model...

I would not expect you to be able to use the LaserJet 2100 driver for a DeskJet F2100!!!

What about the drivers I found? Are they on your system?

Sorry, I should have seen that ..

HP DeskJet F2100

http://www.linuxprinting.org/show_pr...-DeskJet_F2100

Color inkjet printer, max. 1200x600 dpi, works Mostly !

.....

Who knows, maybe something rings a bell for someone. Besides, if you know what you are looking for (what might be the case, if you have experience with these hp-* tools, otherwise you probably don't want to read those details at all), than you don't have to "read all of that".

Would you be so kind, and elaborate these? What do you mean your system "has drivers" for this printer? Where? Are those ppd files? What are their names?
What exactly "shows up" during the search under /usr/share, and what were you searching after?
Yes, I noticed that I don't have the option for a F2100 driver when installing the printer, probably that is what is the problem.
Also, do you mind telling what Slackware version you're using? I'm running -current, and I have cups-1.3.

How is that relevant when the OP has a DeskJet F2100??????????

I found 3 options when attempting to install your printer model. This means that CUPS found those 3 drivers.

/usr/share is where drivers are stored. I just search using all or part of a printer model name---in this case, I just used "2100".

Yep!! Installing the latest CUPS, HPLIP, etc. might help.

I don't use Slackware. I use Arch and I have CUPS 1.4.2, HPLIP 3.9.12, foomatic 4.0.3, gutenprint 5.2.4 (I use gutenprint for my Epson inkjets, but it did not show an option for the DeskJet F2100.

And---did you try getting a PPD file from the HP website?
__________________

Slackware's hplip 3.9.4b contains only 180 ppd files, whereas the official hplip-3.9.12.tar.gz contains 1398... I don't think that between the two versions there have been more than one thousand printer addons... Maybe we (slackware users) just don't get the full package by default.

Anyway, downloaded the hplip package, and just copied over the ppd.gz/ppd files to /usr/share/cups/model/HP and both CUPS and hp-setup recognized the printer, what is now functions properly.

Thx for the tips and suggestions!

Glad to see you got it going!! Please mark the thread SOLVED
