A print operation will create an image of the print job as a temporary file on your hard drive in the print spooler queue, then spool it out to your printer. Your problem seems to be the HDD is short of space. BUT 1¼ MB of space is not much! Have you emptied your Recycle Bin lately?
Check a setting in Adobe. In the Print window, look near the bottom for an "Advanced" button. Click that and look for a check-box for "Print as Image". If that is checked, the entire document will be converted to a set of large bitmaps for every page. The resulting printer spooler file could be HUGE! Try printing with this unchecked.
Thanks for the Adobe response will check.
