I cant install the printer hp lasejet M1120 MFP because the installation cd is gone

Hi Franziska,

HP has not yet released Driver software for your MAC LION however there is a solution for this.
In order to print 2 sided ( duplex printing ) you need to install drivers and it is possible by doing Apple Update.
The link below will give you more details information of how to install the drivers.

MAC LION Driver Update

Once you have done the Update and installed the drivers, you will find the Printer name in Printers list.
Click on Printer Utility and under Layout you will find options to choose 2 sided printing

Sean

My HP LaserJet M1120 MFP will not print if the network cable is plugged in

Re install the tonner and then go to Printer & Faxes settings and delete the all kinds of pending documents and the go to print a new document and after taht send me the result...........what is happening.

There is either a problem with the reader on the printer (unlikely) or the chip on the print cartridge is bad (more likley). You may be able to push the checkmark to continue printing, but some of the HP products will not work when this error is present. Try a different cartridge to determine whether the printer or the cartridge is to blame.

The printer received more data than can fit in available memory.

You might have tried to transfer too many macros, soft fonts, or complex graphics. Press GO to print the transferred data (some data might be lost). Try to simplify the print job or install additional memory.

Hope that helps!

Hey I'm using a HP LASERJET M1120 MFP. But every time I turn on the machine the screen says "Scanner Error 20". How to fix it up? Thanks!
