Once again I would like to draw your attention to the HP Support Forum: Re: After Update to Mac OS 10.13 High Sierra - Printer M553d... - Page 19 - HP Support Forum - 6388132
And I replicate my positive experience with MacOS 10.13.4 Beta, although this version should not be used except for tests:
1) MacOS 10.13.4 Beta allows to print on our HP Laserjet 500 color M551n without any special measures and with various apps that had severe problems before.
2) Some pdfs generated with 10.13.1 or 10.13.2 (did not check 10.13.3) that produced the well-known error "xshow..." before still produce this error when printed with Preview and 10.13.4. So they have to be updated or corrected.
3) A word of caution: /Library/Printer/hp shows a lot of interesting changes and additions. In particular there is a completely new folder "laserjet" that does not look like a very systematic coverage of HP printers. And in the folder "cups" there are many new "...driver" entries. And there are further changes in /Library/Printer/hp. Evidently, lots of things happened nad have to be verified during the beta tests. - Nevertheless, great that someting positive happend. Thank you.
