Not able to see RPAbyPW.Printer in package neither from local

i am working on a solution where an invoice need to consolidate with the support document. once i have the consolidated pdf (till here i am already done with development/testing) i need to make a print , considering the business rules which is to print simultaneously on all 4 printers (there are 4 printer devices installed at client side). in case of there is any queue on any of the printers BOT needs to switch the command to make the print on available printer.

i hope this clears my requirements.

thanks
