<solved> UP5 - Another CUPS issue ? - Samsung clp620nd

[iainrs]

I've identified a problem with my networked Samsung Clp620ND
It has worked very happily since I purchased it in March 2102 (as did the previous clp550n)
I used the 'Unified Linux Driver_1.04' from Samsung.

After the upgrade to UP5 the printer stopped working(from Linux),
Print jobs were sent but did not print (or appear in the job queue)

if I go into system/printing and look at the properties for the printer
in the 'ink/toner levels' tab(!) Status messages I have
errors :
Printer 'clp620-mono':'cups-ipp-conformance-report'
Printer 'clp620-mono':'cups-ipp-missing-job-history'
(these may be red herrings as they are still there after I have gone back)

on speaking to Samsung they admit there is a problem but no date for a solution !

A networked HP Officejet works OK

I have now restored my system to pre UP5 (CUPS 1.5.2) so that I can print but is it possible/wise to exclude CUPS from the 1409 updates that are still outstanding ?

Any advice please ?

You can prevent packages from updating using dpkg

echo "package_name hold" | dpkg --set-selections

Or something like that. After that, apt-get won't update it (with all required dependencies).

To check what have you already locked:

dpkg --get-selections | grep hold

Would I achieve the same effect by unchecking the 6 'cups' modules in mintupdate ?

I really don't know since I've used apt-get to update.
If nobody knows - you can simulate process using VirtualBox.

Problem Solved
I found 'The Samsung Unified Linux Driver Repository' http://www.bchemnet.com/suldr/index.html
which creates a 'Debian type' repository for Samsung printer drivers.
This gives me a more up-to-date-driver.
Now everything works OK

Before using this I ran UP5 (excluding cups 1.5.3) and the printer worked OK
