Character sets on ECC 50

I ususally print on ECC 5.0 with print methd "s" using geneic driver "I2swin"(latin2). This works fine on a pc running saplpd.

Now I am faced with a problem with printer Digital LG 14 which worked fine with method "L" using a custom made device ZEPESC3R with custom made character set 9452. After sap upgradefrom 4.0 to ECC 5.0 this device is not printing special characters.

What should I do as I am doing this 1st time.

thank you verry verry much
