Q6274A is compatible with HP Officejet H470 Mobile Printer series.
While HP website indicates that Laserjet 3500 has an optional 802.11 wireless connectivity feature, the compatible wireless adapter is not indicated.
You may get back to us with the specific mfg part no. of the Printer you own so we can provide you with the compatible adapter or you may also contact HP customer support at 800-888-0262 for your product's detailed compatibility questions.
