One is in the printing program you're using. Make sure your margins and page size are correct. Check all of the options in the program you're using to print twice, three times. If the same program consistently loses 10-15% of the right hand side, you've found your problem. If you are facing the HP Printer not printing left side of page issue then follow these solutions.
How to print a Word document without margins?
In the document you will print without margins, click Layout > Page Setup in the Page Setup group.
In the Page Setup window, change the Top, Bottom, Left and right to 0 under Margins tab, and then click the OK button.
Remove the document in the document cabinet of the printer.
Replace with new printer paper the ancient paper. The old paper may have been moistened on one side or have an irregular surface that caused the problem, and replacing it with new paper will determine whether this is the case.
Start a web browser or word processing program and move to any website full of writing and pictures.
Print the document using the current material and inspect to see if the issue persists on the freshly published document. If If the report is produced uniformly, the problem was the ancient document. Continue to the next stage if the paper is written unevenly as it was before.
Check your pen or toner device position. There may be a screen that tells “Low Ink” depending on your printer, or it may be a straightforward condition indicator that shows green, blue or purple when replacing the cartridge. If the sensor requires substitution, proceed to the next phase. If the sensor needs no substitute, move ahead to stage 10.
Open the compartment region of the ink/toner bottle and extract the item.
Place a fresh cartridge in the carriage of the ink/toner.
Start a web browser or word processing program and move to any website full of writing and pictures.
Print the document and inspect the freshly published document to make sure it is displayed uniformly, if HP Printer Does Not Print Word Documents then the next stage is taken consistently.
