Cannot print from Java application on Samba printer, but can on network printer???
 

I have strange problem with printing from Ubuntu, and cannot figure how to solve it.

Running some custom Java application on Ubuntu 12.04, and it have to print some of the content.

It can print without any problem if it prints on network printer, but printing in stopped when try to print on Samba shared printer (it drops blank page).

In any case, test page can be printed also without any problem.

I was thinking that problem is in java application, but in that case printing will be impossible in both cases (again, it can print on network printer).

I have checked logs, but found no error at all in any case.

It's HP printer HP LaserJet P2015.

Can you give me some ideas where can be a problem? Thank you in advance!
