esc/p to ps2

Hi
i have a big problem

i use succesfuly DOSEMU 1.4 for old accounting program on i386 centos 5

program work well, printing is ok if i connect old esc/p epson directly on 
linux box

but, is there any way (program) to convert esc/p to ps on linux ?

to be clear,
dosemu print esc/p -> captured into file -> converted into ps -> printed 
onto new modern laser

i found this program
http://translate.google.com/translate?hl=en&sl=ja&u=http://www.wheel.gr.jp/~dai/software/bsdprn00-readme.html&ei=mXRFTO3gDNCNONK89fYD&sa=X&oi=translate&ct=result&resnum=1&ved=0CBUQ7gEwAA&prev=/search%3Fq%3Desc2ps%26hl%3Den%26client%3Dfirefox-a%26hs%3DF1U%26rls%3Dorg.mozilla:en-GB:official%26channel%3Ds

but it is on japanese, wery difficult to translate. i tried to compile on 
centos 5, succesfull, but program does not recognize all esc/p commands or i 
don't know how to use

is there any other solution for esc/p -> ps conversion on linux ?
tnx in advance
