TODO.cups12
===========
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 --tdeconfig
-----------------------------
* 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
- LimitRequestBody
- LogFilePerm
- MaxClientsPerHost
- MaxCopies
- PrintcapGUI
- 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
- BrowseLDAPPassword
- BrowseLDAPServer
- BrowseLocalOptions
- BrowseLocalProtocols
- BrowseRemoteOptions
- BrowseRemoteProtocols
- DefaultEncryption
- DefaultPolicy
- DefaultShared
- JobRetryInterval
- JobRetryLimit
- PassEnv
- Policy
- SetEnv
- UseNetworkDefault
