and the printer would only print however a series of unrelated signs / letters / in a row;

i found a solution here on how to install the printer "manually" and now it functions, but this not simple as Linux should be.

sudo lpadmin -p et4750 -v ipp://127.0.0.1:60000/ipp/print -E -m everywhere

(request).

printer-driver-escpr

because i am not able to install "lsb-package" at the moment, but it won't help with duplex-printing.

maybe i am doing something wrong here?

and now LSB is not present or seems not installable.

i tried to add Ascii to sources, but this mixed things up, and seems not a way forward.

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 lsb : Depends: lsb-core (>= 4.1+devuan2)
       Depends: lsb-graphics (>= 4.1+devuan2) but it is not going to be installed
       Depends: lsb-cxx (>= 4.1+devuan2) but it is not going to be installed
       Depends: lsb-desktop (>= 4.1+devuan2) but it is not going to be installed
       Depends: lsb-printing (>= 4.1+devuan2) but it is not going to be installed
       Depends: lsb-languages (>= 4.1+devuan2) but it is not going to be installed

Any idea on how to install

on Devuan Beowulf for the official printer drivers from Epson, or is this package obsolete (hence also the official printer drivers, atleast as far a §Devuan is converned?)

Downloaded the libpng12 here
https://packages.debian.org/jessie/amd6 … 0/download

and now lsb package installs, problem solved.

I don't remember the exact details, but when libpng16 came about, libpng12 got left behind, with the result of needlessly but forcefully deprecating dependent packages. Whatever the case was, the "missing" libpng12 from jessie installs without issues on ascii (and both are merged directly from Debian).

The following packages have unmet dependencies:
lsb-desktop : Depends: libpng12-0 but it is not installable
               Recommends: libqt3-mt (>= 3:3.3.6) but it is not installable
E: Unable to correct problems, you have held broken packages.

Until this is not solved, there seems no way to install the epson-driver package from the homepage.

# apt-get update
# apt-get -f install

to ensure you have a workable apt state.

Thereafter a normal ad-hoc installation

# dpkg -i epson-inkjet-printer-escpr.deb
# apt-get -f install

should work fine.

Still i'd be happy if i could be able to install the "lsb" package, as this would allow me to install the official drivers (also the driver for Fax which seems missing; ).
