I have owned both printers > a year without difficult.
I upgraded to High Sierra about a month ago.
I have had no printer problems until yesterday.
I upgraded to the new drivers yesterday after appearance of the trouble;
only other issue has been intermittent very slow loading of url's in Safari 11.0.2.
I am at a loss how to correct this printing issue (and I use horizontal mode a lot!)
If you have the time to walk me through landscape/portrait settings, I would be very appreciative.
(Holidays are not an issue for me, just being satirical.)
I am not yet sure but it appears the problem is confined to Pages 6.3.1 which is installed on this MBPro computer but not on a MacBookAir I use for much composing of horizontal documents but 5.6.2 on the MBAir which prints normally on the (wireless) linked HP LaserJet CP1525nw (a color laser device and is also not using High Sierra but Yosemite because of serious problems with the dictation program [Dragon Dictate for Mac by Nuance] I use interfacing with Mac versions of MacOS);
I now see that the template for printing on the 2 different computers and different versions of MacOS and Pages is utterly different! I inadvertently went to Pages 6.3.1 on MBP with High Sierra a few (?) days ago and I have not familiarized myself with this new version at all! And it is when I transfer a Pages document from MBA to MBP that the printer thing occurs! I'll work on that this weekend and come back with reply about what happens!
I hope those last 2 paragraphs make some sense in spite of my hideous composition!
