You can find a lot of Wireless Printer Server from manufactures of SOHO Wireless products. Though the Specifications seem to be impressive, I doubt their operability and the ability to talk to the Printers. Some of them don't talk to GDI or PCL 5 or PCL 5e based printers. Many of them won't work with a multifunction printer either.
In such case, a Wireless Ethernet Adapter seems too impressive; just plug the Wireless Adapter to the Ethernet port of the Printer (I am sure, many of the printers comes with a RJ45 Connectors). These Wireless Adapters are Driverless, and operate on firmware. Some of them have HTTP based management console for easier management.
