Comentários

Se o inicial PrintTicket solicitar a funcionalidade de impressão que a impressora não suporta, o driver de impressora resolverá todos os conflitos para produzir um tíquete viável.If the initial PrintTicket asks for printing functionality that the printer does not support, the printer driver resolves all conflicts in order to produce a viable ticket.
