This is an excellent program; however certain functions are difficult, especially "moving text" and aligning the text to create a uniform picture.

I find it tedious that I cannot page or scroll down with my cursor on the document. I also like pdf filler apps used by realtors that let you initial and then step to the next blank to complete.

Great app! Use it on my phone which is great and handy in situations where documents need to be signed and done in a hurry. Only down fall is mailing documents sometimes gets sent to spam or junk mail. So tell your recipient to check their spam box just incase.

Initially Initially, it was a bit difficult to insert the text; but after a while I discovered the "T" tool for aligning texts. I also like the fact that I had choices for signatures.

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.

Time required for transmitting fax depends on quality of the phone line, and content that is being sent. For documents that contain mostly text it usually takes approximately 1 minute per page for the document to be delivered.
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.
