Documents you receive from 3rd parties may not alway work that well with your local printer and the printer may prompt to insert paper of a size different that what is loaded.
With almost all printers this can be overridden at the printer by following the prompts. However, if you do not go to the printer to claim your print job and the printer is a busy one it will queue all future print jobs and frustrated other users will send their print job multiple times because the did not 'her' it printing. The result is usually a mess.
Hence
When printing PDF files it is generally a good idea to hot Ctrl+P instead of just the printer icon as Ctrl+P (or file/print etc.) will bring up a menu that allows you to fine tune a print job, i.e. you may only need the circuit breaker layout from a 1.600 page Vehicle Maintenance Manual. To this end please note the complex page notation in below screen shot.
Areas in red should always be set as shown for all 3rd party PDF documents especially if from the Americas where A4 is not in use.
Printers too have settings to adjust any odd sized documents and a distinction is made between 'shrink to fir' which is always to be used and scale to fit which means scale for instance an A5 sized job to A4 which may not always be desired. Below example from an OKI MB472 to make sure whatever the source it is printed on the loaded A4 paper, if the document is US legal it will be proportionally scaled (shrunk) to fit A4 and if it is A5 it will be proportionally zoomed to fit A4
In closing let me just reiterate that almost all software packages have more than one way to print and clicking the PRINT icon with your mouse may not just take longer because you have to 'take aim' with your mouse, it can also produce undesirable result such as printing half a rain forest of a large document or forcing the printer to ask you for a paper format you do not have at your disposal. Ctrl+P (Windows) and Command+P (Apple) are the stock 'controlled' print commands and i recommend you make it a habit to used them.
Thanks for reading.
