Jo allemaal,

nu ik al enige tijd bezig ben met het verbeteren van een IDE, ben ik ook bezig met het fixen van een print probleem. Deze is opgelost en er is een mooie oplossing gevonden. Mijn probleem is echter: op de eerste pagina wil ik wat model info displayen (lukt prima), maar op de pagina's met de pagina index != 0 wil ik gewoon een paginanummer laten zien (zie code). Dit lukt echter niet, alleen op pagina 1 wordt er extra informatie afgedrukt, wie kan er zien wat er mis is?
