I would have posted this at the LB Umbrella Forum, since the subject isn't specifically related to LBB, but annoyingly it has been closed.
Over at the LB Community Forum somebody has asked how to change, programmatically, the font used by LPRINT. This is a simple question with a straightforward answer, since it's a documented feature that Liberty BASIC has had since version 4:
PrinterFont$ = "courier_new 10 italic"
lprint "This text will appear in "; PrinterFont$
Mysteriously, however, the replies at the Community Forum (from two LB 'experts') make no reference to this useful feature, but instead suggest that it is difficult or impossible to achieve ("To do it programmatically you would need to load, edit and save the .ini file then restart Liberty").
Why? Does PrinterFont$ not work properly? The above code seems to work for me, in LB 4.04 and LB 4.5.0. Of course it has the limitation that you can't change the font within a 'page' (a restriction lifted in LBB) but the OP didn't specifically ask for that.
So what's the problem, or did two people far more experienced in LB than I am simply forget about this feature?
