|
|
===========
|
|
|
|
This is a list of features that need to be implemented in KDEPrint for
|
|
KDE4.
|
|
|
|
Many gaps have opened by the continuing CUPS 1.1.x development already
|
|
(which added quite some new parameters and features), while KDEPrint
|
|
development got dormant in recent years. Plus, even more new gaps by
|
|
the recent CUPS 1.2 release (which added even more new features).
|
|
|
|
|
|
---------------------------
|
|
In General:
|
|
---------------------------
|
|
* a GUI to configure client.conf is missing [1.1]
|
|
* a GUI to configure snmp.conf is missing [1.2]
|
|
* a GUI to configure subscriptions.conf is missing [1.2]
|
|
|
|
Other stuff that's new:
|
|
|
|
- port monitor support [1.2]
|
|
- unique job IDs support [1.2]
|
|
- print a self test page (if driver supports CUPS command file format,
|
|
you can now print the printer's self-test page) [1.2]
|
|
- perform a self-cleaning of print heads (if driver supports CUPS
|
|
command file format, you can now clean print heads) [1.2]
|
|
- per-printer sharing support [1.2]
|
|
- per-printer error policy support [1.2]
|
|
- per-printer operation policy support [1.2]
|
|
- IPP notifications support [1.2]
|
|
- cupsd.conf environment variable support [1.2]
|
|
- driver interfaces support (CUPS 1.2 supports "driver interfaces"
|
|
which allow a driver to advertise the printers it supports and
|
|
automatically generate the PPD file as needed) [1.2]
|
|
- improved error handling support (CUPS 1.2 API provides convenience
|
|
functions to get full error message of last request) [1.2]
|
|
- improved "backchannel" support (CUPS 1.2 API provides backends and
|
|
filters with access to information sent back from a printer) [1.2]
|
|
- globalized PPD support [1.2]
|
|
- custom PPD option support [1.2]
|
|
- extended PPD API support (CUPS 1.2 PPD API got added new functions:
|
|
reading from CUPS files; localization of globalized PPD files;
|
|
emitting of arbitrary ranges of options; custom option support [like
|
|
passwords, passcodes, curves, integers, points, reals and strings];
|
|
enhanced JCL support; and access to all options in a PPD file) [1.2]
|
|
- CUPS ICC profiles support [1.2]
|
|
|
|
|
|
--------------------------------
|
|
More specifically:
|
|
--------------------------------
|
|
|
|
kprinter
|
|
--------
|
|
|
|
* add support for "-U username somebody" (or, in a more IPP-conforming
|
|
syntax: "-o job-originating-username=username").
|
|
|
|
* add support for multilanguage PPD files
|
|
|
|
* add support for other CUPS extensions re. PPD parameters; especially
|
|
important is support for handling custom PPD options!
|
|
|
|
|
|
kaddprinterwizard
|
|
-----------------
|
|
|
|
* add support for IPv6 syntax when specifying or parsing network
|
|
addresses
|
|
|
|
* add support for new "snmp" backend in CUPS 1.2.
|
|
|
|
The snmp backend can auto-discover most printer types which are
|
|
attached to the LAN with a NIC. For a sort of introduction to its
|
|
features see http://www.kdedevelopers.org/node/2138/.
|
|
|
|
To check it from the commandline, just run it without any parameter:
|
|
"/usr/lib/cups/backend/snmp" (Ubuntu Dapper users have it disabled
|
|
by default; just run "/usr/lib/cups/backend-available/snmp". If you
|
|
have network printers in your LAN, you'll likely see an output like
|
|
|
|
network ipp://10.162.2.92:631/ipp "Ricoh IPP Printer v2.0" "Ricoh IPP Printer v2.0 10.162.2.92" ""
|
|
network socket://10.162.2.93 "infotec ISC824" "infotec ISC824 10.162.2.93" ""
|
|
network lpd://10.162.2.94/passthru "Canon iR5000-6000" "Canon iR5000-6000 10.162.2.94" ""
|
|
|
|
kaddprintwizard should be able to parse the CUPS snmp backend's
|
|
output for adding the auto-discovered network printers to the
|
|
local setup.
|
|
|
|
* add support for the following parameters in printers.conf (which
|
|
where newly added in CUPS 1.2.0):
|
|
- ErrorPolicy
|
|
- OpPolicy
|
|
- Option
|
|
- PortMonitor
|
|
- Shared
|
|
- StateTime
|
|
For information purposes: currently supported parameters are:
|
|
- Accepting
|
|
- AllowUser
|
|
- DenyUser
|
|
- DeviceURI
|
|
- Info
|
|
- JobSheets
|
|
- KLimit
|
|
- Location
|
|
- PageLimit
|
|
- QuotaPeriod
|
|
- State
|
|
- StateMessage
|
|
|
|
|
|
|
|
kaddprinterwizard --kdeconfig
|
|
-----------------------------
|
|
|
|
* add support for unix domain socket support (was added in CUPS 1.2.x)
|
|
|
|
CUPS 1.2 newly introduced the option to communicate via "unix
|
|
domain sockets" for local cases (CUPS client and server on the
|
|
same host [=localhost]. That means, you can now have 2 types of
|
|
"Listen" directives (concurrently):
|
|
Listen localhost:631
|
|
Listen /path/to/domain.sock.name
|
|
|
|
Support for unix domain socket communication should be added at
|
|
"CUPS Server Settings" --> "Server information".
|
|
|
|
|
|
kaddprinterwizard --serverconfig
|
|
--------------------------------
|
|
|
|
* Add support for currently unsupported cupsd.conf 1.1.x parameters.
|
|
All in all 15 unsupported parameters:
|
|
- ConfigFilePerm
|
|
- FaxRetryInterval
|
|
- FaxRetryLimit
|
|
- FileDevice
|
|
- FilterNice
|
|
- Include
|
|

|
- ReloadTimeout
|
|
- RootCertDuration
|
|
- RunAsUser
|
|
- ServerTokens
|
|
|
|
* add support for cupsd.conf parameters newly introduced in CUPS 1.2.0.
|
|
Note, "RunAsUser" is no longer supported in CUPS 1.2.x!
|
|
All in all about 18 new parameters (on top of the 15 unsupported ones
|
|
from CUPS 1.1.x):
|
|
- BrowseLDAPBindDN
|
|
- BrowseLDAPDN
|
|
