Which solutions are available for printing on the iPad to a HP LaserJet 1020 printer?

I have an HP LaserJet 1020 connected to an IOGear network print server.

Currently the iPad doesn't support printing out of the box, however I have heard there are several third-party solutions on the market, each with a mixed bag of results.

Which solutions are available and which is the most versatile or successful?

Apple has indicated printing will be available with the iOS 4.2 release, currently scheduled for November 2010.

I've looked at this issue before for my parents. Apparently there are many solutions that do part of the full range of (document types, printers) well.

My suggestion is this: http://mobile.eurosmartz.com/prod_index.html#comparison

I'm trying out PrintBureau. Wish they had a demo version so I could test before buying.

Print n share is an app I use on my iPad. I don't have an AirPrint enabled printer, but with this app, I can print via the weprint server on my Mac from the iPad. I would definitely recommend taking a look at this app. luck
