Cannot print using Cups

Hi,
my printer Dell C2660dn is old, but still working.
However I cannot print using Cups.

Checking Cups error file I can see this:

I think this issue is caused by file /usr/lib/cups/filter/Dell-C2660-Color-Laser/DLPSACJFilter that is provided by Dell’s driver package for Linux.

In my understanding this is a 32-bit binary:

❯ file /usr/lib/cups/filter/Dell-C2660-Color-Laser/DLPSACJFilter
/usr/lib/cups/filter/Dell-C2660-Color-Laser/DLPSACJFilter: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.4, with debug_info, not stripped

And I don’t think this would work with MicroOS.

Can you please advise how to fix this issue?
In my opinion there are 2 options:

  • Make OS work with 32-bit file /usr/lib/cups/filter/Dell-C2660-Color-Laser/DLPSACJFilter
  • Use Cups with generic driver to work with this printer

is port 515 and 631 open in the firewall - they are required to print via ipp.

The printer may well be supported by driveless printing (IPP Everywhere). If so, allow port 631 (IPP printing) and perhaps port 5353 (mDNS port for device discovery).

Hello,

there’s no firewall issue (or similar) because I don’t enable any firewall on MicroOS.
I verified already that relevant ports are open:

❯ nmap dell-c2660dn-clp

The solution for this issue is to switch to Driverless Printing and Printers; the Debian Wiki provides all details required.
Fortunately my printer provides IPP and Bonjour (mDNS) that is required for printer discovery and driverless printing.
I selected cups-filters PPD Generator and my printer works as expected.

Thanks for supporting this issue!

Yes, as I had hoped. Glad to have been of guidance.
