There are newer printer drivers, but there is no support for Windows GDI printers as their interface is vendor-defined and hence not implemented. What 3.1.4 supports are postscript driven printers...

Not that I know of, but every decent assembler should allow you to create a macro that converts a word-sized argument to two dc.b directives. No. The segment loader would crash, at least on a 68K.
