I don't throw anything away (except my own mistakes!)
The RxWriter software in AC is set up so you can print 4 Rx to a page (so you can use full size sheets in your printer)
You can also print 1 Rx to a page, which by default comes out to a standard 81/2 x 11" size.
The Rx paper can be purchased either in solid sheets, or 1/4 scored sheets.
I buy scored paper, and divide it into quarter sheets, and put a stack of quarter sheets into the paper tray in the printer. Most printers will take the small sheets.
The next thing is to use the printer options (its in the print driver software) to print to the quarter sheet.
If you set set up a custom paper size (5 x6" works well), and set the printer driver so it automatically sizes the print to the paper size, then print "one Rx per page" from AC Rx writer, you have a decent Rx printer.
Sounds sort of complicated -- it's not, once you figure out the options in the printer driver.
Advantage is any laser printer (maybe inkjet too) will work as Rx printer. And since used printers are cheap -- even network printers -- you don't have much invested. I would put one in every exam room except for the clutter, so I just use one printer out in the hall.
The full size printers are big, of course -- I'm sure the dedicated Rx writers are smaller
