the problem with these printers i mostly the parallel port, practically all of them uses it
not much pcs has those anymore
supposedly all epson, panasonic and similar old models work perfectly but the parallel port on recent kernels seems to misbehave
cups supports so many old printers but if parallel port doesn't cooperate...
since printing is done with the help of cups and cups is property of apple now parallel port has no sense anymore
right now a laser printer or a plotter is more practical from multiple point of views
