ok so i have a Hp laser CP1215, plugged in to my desktop via usb. should i get the network adapter and plug it in to my wireless router? if i do can i still print from my desktop which is wired to my router? Or should i get the print server? and use the usb dongle? which will be faster? i have 4 computers that need to print. http://www.shopping.hp.com/product/printer/inkjet/wireless/4/accessories/Q6236A%2523A2L or http://www.shopping.hp.com/product/printer_networking/printer_networking//4/storefronts/Q6275A%2523B1H ive tried the share printer way it didnt work.
