Smartform is ok with print preview but prints with character problems

Hello guys,

I have developed a smartform and it worked Ok  when i have printed the smartform.

Till yesterday when users print the print shows with character deficiencies like illegal chars

writes like Courier 12..

But when you do a print preview it all looks ok

when you print and see the log at sp02 it gives errors like conversion

Character converter active when first problem occurred

Data was saved with character set 4103

Data will be converted to character set 1634 (synt = 9612)

Errors occurred processing this print request

OTF module: Unknown print control SPORT should be output

OTF module: Unknown print control SPAGE should be output

please help
