I use the printer only in the WLAN - not with USB. If both are on, the scanner is sometimes not found. If
it only runs in WLAN's all super. Use this with 2 Imac under OSX 10.7.5 and 10.10.2 Yosemite with the Canon software. Likewise with 2 Ipads. The Canon printer app is very good.
Had first 80g of standard copy paper and because the quality was quite good. Now I use the HP C1825A Bright White Inkjet Paper
90g (also available here at Amazon) and that is very good. No difference from the color laser. I have stayed at Karstadt bought for testing.
Really good is the automatic document feeder to 50 sheet. 10 leaves pure and copy-ready. Likewise, scanning multiple pages
doing very well. However, scanning is only on the Canon software. Photoshop or Acrobat Pro 10.1.12 does not recognize the scanner. But also CS4. It will all be scanned into the Documents folder. Is OK for me.
The printer can also duplex - ie printing on both sides. When copying will not do. I have certainly not found.
For the price a super machine with super quality. Have recently a HP black / white laser for about 200 euros tested and the
Canon can here easily keep up with the HP paper. Photo paper I have not yet tested - but should go according to Canon also.
