HP DesignJet T790 and T1300 Printer Series - Using your printer

●
Did you set the print-quality to Best or Max Detail? Best-quality and maximum detail prints take longer.
●
Did you specify the correct paper type when loading the paper? Some paper types require more time for
printing; for example, photo and coated papers require more drying time between passes. To nd out the
printer's current paper type setting, see View information about the paper on page 40.
●
If your printer is connected by network, check that all components used in the network (network interface
cards, hubs, routers, switches, cables) are capable of high-speed operation. Is there a lot of traic from
other devices on the network?
●
If your printer is connected by USB, make sure that the USB host controller and the USB hubs used (if any)
are USB 2.0; and check that the USB cables are USB 2.0
certied.
●
Did you specify Extended drying time in the front panel? Try changing the drying time to Optimal.
Communication failures between computer and printer
Some symptoms are:
●
The front-panel display does not show the Receiving message when you have sent an image to the printer.
●
Your computer displays an error message when you are trying to print.
●
Your computer or printer hangs (stays idle), while communication is taking place.
●
Your printed output shows random or inexplicable errors (misplaced lines, partial graphics etc.)
To solve a communication problem:
●
Ensure that you have selected the correct printer in your application, see Printing on page 46.
●
Ensure that the printer works correctly when printing from other applications.
●
Remember that very large prints may take some time to receive, process and print.
●
If the printer is connected to a network, try using it when connected directly to your computer through a
USB cable.
●
If your printer is connected to your computer through any other intermediate devices, such as switch boxes,
buer boxes, cable adapters, cable converters, etc., try using it when connected directly to your computer.
●
Try another interface cable.
●
Ensure that the graphic language setting is correct, see Change the graphic language setting on page 30.
●
If the printer is connected by USB cable, try disconnecting and reconnecting the USB cable. Also try using a
dierent USB port on the computer.
