Printing Checks on HP Laserjet Printer

[Hautbois16]

I am totally blind and needing to print personal checks.  The blank checks I use are of the business length with raised lines to mark all the fields by touch.  I want all the fields on the check EXCEPT the signature field to print, and I want to know whether I can make this printer do that.  When I open the "front door" where a manual feed of an envelope or other item could be fed, it appears to me that the check is longer than I can accommodate with those "slider guides" pushed out to the maximum.  Still, the printer is supposed to be able to print envelopes through that manual door, though I don't know how to do it.  Again, it appears that the slides don't go out wide enough to accommmodate an envelope.  I believe that I am doing something wrong or don't understand how I am supposed to do that printing.  My ancient DOS printer (KXP2180 PANASONIC PRINTER) has gone bad, and I must find a way to print personal checks.  I will appreciate any suggestions you can give me.  I understand, of course, that I will have to use either a template in MS Word or something else to create the "printable form" to place the information correctly on the check form.  I have a way to measure distances from the top and from the left end to know where the information belongs on each field; I did that years ago for a "cheap and dirty" word-processing template with tabs for the fields on my old word-processor.

What you are missing is you feed the envelops and check in landscape mode. In other words the shorter side of the check or envelop is the leading edge into the printer. If using a word processing or check writing program it should have menus that allow for positioning the media in the landscape orientation and changing the orientation in the driver from portrait to landscape.
