ive tried heaps of pdf repairs from quickbooks, ive tried repairing quickbooks, ive tried uninstalling all printers and removing them. none of this works.

i can print invoices but not save as pdf. 

i can however use word and save as pdf in that.

ive had enough of quickbooks, its never ran properly always have issues. def would never recommend to anyone or pay $1000 for rubbish software like this again.

i have invoices to bill and cant do so due to this issue,
