3. Tap Scan for Printers. In response, LabQuest will

search for available printers.

TIP!

If LabQuest is unable to locate a desired

network printer, try accessing it directly by tapping

Enter IP Address or Name.

4. Select the desired printer and tap Install.

5. Select a driver for your printer. For more

information on determining which driver you

should select, see

www.vernier.com/til/3657

Troubleshooting

Even if a driver is found, printing may still fail due to an incompatible printer. If you are sure

that the printer is compatible and you are still getting an error, it may be caused by one of the

following conditions: out of paper, out of ink/toner, a door on the printer is ajar, a paper jam, or

you may have selected the wrong printer on the Print Options screen.
