Seemless interaction so far, good online support.
The company does not yet have the CA Residential Purchase Agreement and Escrow Instructions (effective 11/26/14) available, my only knock. May not be released yet to public as a non-draft document. Ralph 12/13/14

Invaluable! I use this every workday! I am continuously learning more ways to utilize the features PDFfiller offers. Sometimes I have found my answer before customer service can but we are all learning. Thanks

The program requires no OCR software which in my experience creates lots of problems for most "Form Filler" software I have tried to use in the past.

How do I fax multiple documents at once?
Click the “Start” button and move cursor to “All Programs” to expand the menu, then click “Windows Fax and Scan.” Click the “Fax” tab located in the bottom left corner of the window. Click the “New Fax” button. Type the fax number you want to fax multiple documents to in the “To” field.
Can you fax more than one paper at a time?
When sending a multiple-page fax, it is important to note the total number of pages, including the cover sheet, so that the recipient can be sure that she receives all the pages. Once complete, your fax machine may print out a transmission report that will indicate how many pages were sent.
How many pages can you fax at once?
For traditional fax machines, it's recommended that you submit 50 pages or fewer. For an easier and reliable transmission, start with batches of 15 pages.
How do I fax multiple pages at once?
Put the pages in all at once, dial the recipient's number, and press start. The pages will scan and fax one by one, and you'll get one confirmation page at the end.
Do you fax one page at a time?
If you have only one page, you can use either function. If you have multiple pages, the paper feeder usually works better. When using the paper feeder, you can insert all of your pages at once. Your fax machine should have an icon that indicates which direction that papers should be facing in the paper feeder.
How do you fax papers?
Place the document you want to send in the document feeder. Enter the fax number you want to send to, including and extensions to dial externally, and any international dialing codes. Press Send or Go (depending on your fax machine model)
How many papers can you fax at a time?
For traditional fax machines, it's recommended that you submit 50 pages or fewer. For an easier and reliable transmission, start with batches of 15 pages. Fortunately, online fax services are on the rise these days.
Can you fax multiple pages at once?
Most faxed documents consist of multiple pages and thanks to the standard technology built in to the vast majority of fax machine models, sending multiple page documents with a fax machine requires just a few steps. Fill out a fax cover sheet. Place pages into the fax machine's document feeder.
