Self-dis­con­nect­ing printer

Mac Format - - GENIUS TIPS -

Q Print­ing to my Ep­son DX7400 printer works nor­mally, but its Dock icon and pop-up win­dows warn that it isn’t con­nected. This started af­ter up­dat­ing to 10.12.5, with the printer con­nected to my Mac mini and shared from there. Is this a net­work prob­lem? by D av i d Wa r d A Be­fore wor­ry­ing about whether there is a net­work prob­lem, first check the ver­sion of the printer driver you’re us­ing. If you have Ep­son’s own soft­ware, note that it hasn’t been up­dated since Novem­ber 2016, and will prob­a­bly be ver­sion 2.22. If you have the driver pro­vided by macOS Sierra, it should be ver­sion 9.0, and up­dated via the App Store.

Unin­stall any older driver and other Ep­son soft­ware first. Next, in the Shar­ing pane on your Mac mini, turn Printer Shar­ing off. Then in the Print­ers & Scan­ners pane on both Macs, select the Ep­son in the left side and click on the ‘–’ tool below to re­move the printer. Close that pane and open it again, and add the printer back us­ing the ‘+’ but­ton. That may trig­ger a soft­ware up­date in the App Store app, to fetch and in­stall its cur­rent driver.

Once you’ve turned Printer Shar­ing back on, in­stall the printer again on your other Mac, and you should find it re­mains prop­erly con­nected. If not, check that your net­work is all in good or­der, with all net­work ca­bles se­curely in­serted and safely routed.

Printer prob­lems? Make sure you have the lat­est driv­ers from the App Store.
