same is happening to me on my desktop mac but it works on my laptop.
Do you see any error messages while priting? Do you see the job in the printer queue?
No, there are not any errors and the job never goes into the print queue
Windows 7 professional 64 Bit Adobe Acrobat Reader X
Can print everything else on K550 But No PDF.
Can print PDF's on two other HP printers.
As stated No errors, Print never goes to printer que, just disappears ??
Funny used to print PDF before some Update ???
Was it Windows or Adobe that broke the PDF printing??
