Printing with Save2PDF (or PrintCentral) app

[kaibob]

I recently purchased the save2pdf app, which, among other functions, prints directly to a wifi printer (the printer is not on a network). This works well with one exception--I first have to open the iPad's "Settings" app and change "Choose a network..." from my wireless router to the "hpsetup" entry. After printing, I have to change "Choose a network..." back to the wireless router. Is there some way for save2pdf (or similar app) to print without making this change?

I believe save2pdf uses the same print process as the developer's other print apps, such printcentral. My printer is an HP Deskjet 6988.

BTW, I sent a support request to the developer, but they ignored the question and responded with a boilerplated response.

Thanks for the help.
