I used PSgs driver because I had to support Russian characters printing and I
had failed to to it with pure PS driver

a2ps-4.13 as I remember. Tomorrow I can define it more exactly.

Unfortunately I can't now access the printer but I found a test
piece of paper with error messages. They are printed over the text so
the following re-printing might be incorrect:
ERROR: undefined
OFFENDING COMMAND:~
STACK:
(
?    ?    ?       ?            ?     ?  ?    ?   ?   ?    ? 
)

OK. I'll do it within a month (because I can access and test the printer seldom
;( )

Sorry. It was a mistype. I meant "-dLanguageLevel=2".

I agree completely. That's why I wrote to the mailing list.

OK. After updating ghostscript and a2ps I'll test the printing again.
