Pastovi problema. Identifikavau tokius problematiskus dokumentus:

Producer: Winnovative HTML to PDF Converter 9.12, Format: PDF-1.4
Producer: iText 2.1.3 (by lowagie.com), Format: PDF-1.4

Abiejuose dokumentuose yra segmentai su bar kodais

Nors kitus PDF dokumetus spausdina normaliai pvz.
Producer: LibreOffice 3.5, Format: PDF-1.4 <<< be bar kodu
Producer: GPL Ghostscript 8.15, Format: PDF-1.4           <<< be bar kodu
Producer: Telerik Reporting 7.2.13.1016, Format: PDF-1.6 <<< be bar kodu
Producer: iTextSharp 4.1.6 by 1T3XT, Format: PDF-1.4 <<<< yra iterpatas 
ir bar kodas

Pabandziau ant ubuntu dar viena problematiska PDF dokumenta, kuri taip 
pat ilgai virskina, perspausdinau su print to file taip:

Producer: Winnovative HTML to PDF Converter 9.12, Format: PDF-1.4 >>>>>> 
Produser: cairo 1.10.2 (http://cairographics.org), Format: PDF-1.5

Rezultatas: toks pat spausdinimo 2min / 1lapas  spausdinimo greitis

ant Windows XP per:
CutePDF programa (Producer: GPL Ghostscript 8.15, Creator: PScript5.dll 
Version 5.2.2, Format: PDF-1.4), perspausdinau ta pati dokumenta ir 
paleidau spausdinima per linux, lapas islindo per 26sec (reiskia 
sutvarke greiti).

Nitro PDF Driver 5 (Producer: BCL easyPDF 6.00 (0320), Creator: NitroPDF 
6.0, Format: PDF-1.3), perspausdinau ta pati dokumenta ir paleidau 
spausdinima per linux, lapas islindo per 26sec (reiskia sutvarke greiti).


Isvados:
Galima perspausdinant "letus" dokumentus ant PDF kitos programos ir 
spausdinti per lazerini printeri greiciau, taciau tai kainuoja 
papildomai laiko ir pastagu.

Jei butu pacio kuriami tie PDF dokumentai, tai galeciau nuo pat pradziu 
rinktis kita PDF printeri ir taip klausimas butu issprendziamas, bet 
dabar jis jau toks gaunamas ir ji reikia spausdinti fiziskai ant iprasto 
printerio.
