My Mac has lost connection to my wireless 8715 officeject printer

[KAT211]

My MacBook Air was printing fine but now says looking for printer. Of 3 mac's in house 1 will print other 2 won't. only difference I can see is that the 2 that won't print say HP OfficeJet Pro 8710 [F619B1] (2) and one that prints says HP OfficeJet Pro 8710. How do I get rid of the [F619B1] (2)?
