Yes printshop has 4 assets, however, the 'failed' comment is not accurate yet.

3 assets are mining related and dependent on LTCgear.

Bearmining is a pass-through for LTCgear and has failed if LTCgear has failed, this is yet to be decided.

SafeHash has a guaranteed value in case of failure backed by USDbitfx and similar assets.  This was also dependent on LTCgear and printshop has been buying them back if people want to sell. There was one large (company?) investor in this and they may have wanted to exit their position.
See https://nxtforum.org/index.php?topic=6474.msg144131#msg144131 for buy back message.

dailytrade also dependent on LTCgear was released last month and printshop has been buying them back if people wanted to sell.
These 3 have only failed if LTCgear has failed, the dependencies were clear to buyers and in the case of the pass-through asset printshop was extremely clear about the risks.

The fourth asset KNS has not failed, in any sense. It has, however, suffered a set back due to loss of income from the other assets.

On the NXT Asset Exchange, Mining assets and their issuers receive negative karma for every delay in payment. Given LTCgears lack of payment it is understandable that printshop's karma would be more negative than positive. If you do not believe this just look at the LTCgear thread and the emotions expressed there (before moderation). This is not the only source of negative karma but I believe it is the largest component.

I expect cassius69 that you provided some of the negative karma, is this correct?
