The printers do not come up with names in the sequences you show, and I had no luck changing the defaults for the Epson, altho the information that is provided shows what's wrong. here's the sequence at my place:

doug@linux1:~> lpstat -a epson accepting requests since Fri 29 Jan 2021 04:03:31 PM EST HP_LaserJet_Pro_M201dw accepting requests since Fri 29 Jan 2021 06:43:20 PM EST HP_LaserJet_Pro_M201dw_34CF8A_ accepting requests since Fri 29 Jan 2021 04:12:05 PM EST doug@linux1:~> lpstat -d no system default destination doug@linux1:~> lpoptions -l You have not specified which printer.

lpoptions -p epson -l

PageSize/Paper Size: *Letter Legal A4 4X6FULL 2L 8x10 << lpoptions PageSize/Paper Size Letter 8.5X11 Wrong syntax.

I showed examples in my post, and you do not follow them, or read the manual.

Usage: lpoptions [options] -d destination        lpoptions [options] [-p destination] [-l]        lpoptions [options] [-p destination] -o option[=value]        lpoptions [options] -x destination and so on. . . . Sigh... Look at my post on how I did it.

lpoptions -p epson -o "PageSize/Paper Size"=Letter

or perhaps

lpoptions -p epson -o Size=Letter

  lpoptions -l

will tell you the options for the current default printer.

First you have to find out what printers you have. For example:

  cer@Telcontar:~> lpstat -a   cp1510n_ps accepting requests since 2021-01-30T14:42:21 CET   cp1515n_hpijs accepting requests since 2020-10-23T22:15:18 CEST   cp1515n_pcl3 accepting requests since 2020-09-29T00:00:55 CEST   cer@Telcontar:~>

and which is the default one?

Apparently there is no default. When I ask a page (or pages) to print, I get a dialog asking which printer. I take that back. Everything I've gone thru here says that the system accepts the epson as the default. What I need (I think) and I forget if I ever knew, is how to get the default options for the laserjet, since that out to tell me what the exact format for the US letter size is, and then maybe the lpoptions thing will let me put that in. /snip/

Well, I told you from the start: it does not work. And then I told you: Well, try to edit the options directly on the file and find out if the printer obeys. You have not done that yet. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)

Maybe I issed something, but if you fire up the CUPS menu (localhost:631) , select the printer -> maintenance -> change default values, there are drop- down menus for each value....

I don't have clear if it works for him or not. I asked:

You can use either doug's password, or root's password.

He replied:

I have the same password as boot and as my user. CUPS doesn't like that password, and I have no other.

I think you came in late to the file: CUPS asked for my password and I gave it the only password I use, which is the same for bootup and for root user, and it refused it. --doug

Correction, just in case, root user must be typed in lowercase characters. The upper case ROOT was meant as emphasis.

Just before this message, I recollected from long ago, and with a bit of tickle from someone here, that the user name for CUPS is root, and I put that in, and bob's your uncle! Printer now knows to use Letter size, which is what 8½x11 is called, and all is good. And thank you for coming right out and telling me that, in case I hadn't been able to dredge that up. It is certainly not obvious, since everywhere else that I'm aware of, the expression "user name" wants MY user name. --doug

Because it can be ANY user on your system, and you have to decide which to use. But, as you want to change the default options machine wide, it *obviouysly* needs you using "root". - -- Cheers, Carlos E. R.

when cups asks for user name, use "root" and the password you use when you use "su -".

Certain operations on a Unix/Linux system require the credentials of almighty “root”. Accept this fact of life. Just for completeness (and probably best if you don't read this, Doug). There are some linux distros, most notably Ubuntu, where by default the root user is disabled and all admin is carried out using sudo. So neither the username 'root' nor that username's password are requird to administer the system. I read it. I looked at Ubuntu a long time ago and decided it wasn't for me.
