When converting an html file to postscript, the output postscript file appears to be empty and contains many more pages that the original html file.

Reproducible: Always

Steps to Reproduce:
Content of html page does not matter (original test was simple html page containing an image)
1. html2ps test.html > test.ps 
2. view postscript file with postscript viewer such as ghostscript or convert to another format such as pdf (ps2pdf)

Actual Results:  
test.ps file has many more (blank) pages than the original test.html file

Expected Results:  
Content from html to be displayed in postscript file

Upon further investigation I believe the content is in the postcript file but the drawable area of the pages is offscreen as the page dimensions are wrong.

I have been comparing html2ps output generated on Fedora 28 with html2ps output generated on RHEL7 (html2ps is not available on RHEL8 or RHEL9) and the major difference was page dimensions.

When running html2ps on Fedora it also generates the following error
"Unknown paper type: A4: 210x297 mm"

Paper dimensions are obtained from `paper` command and recently it looks like this was switched from `paperconf` (which is not available on Fedora 38).

29 $default_paper=`paper` || 'a4';
...
48     type: $default_paper;
...
616 if(!$pagew || !$pageh) {
 617   if($width{"\L$paper{'type'}"}) {
 618     $paper{'width'}=$width{"\L$paper{'type'}"} if(!defined $paper{'width'});
 619     $paper{'height'}=$height{"\L$paper{'type'}"} if(!defined $paper{'height'});
 620     ($pagew,$pageh)=($paper{'width'},$paper{'height'});
 621   } elsif($paper{'type'}) {
 622     &dbg("Unknown paper type: $paper{'type'}\n");
 623   }

I can workaround this by setting my own ".html2psrc" config file and adding a paper configuration e.g.

  paper {
    type: A4;
    height: "29.7";
    width: "21.0";
  }

Without any paper settings in config file I get page dimensions (notice the negative offset)

/yL -84 D
/yR -84 D
/Wl -141 F div D
/Wr -141 F div D
/hL -169 F div D
/hR -169 F div D

It looks like the output from `paper` is not a drop in replacement for `paperconf` from previous versions as output is significantly different.

I assume this is not a major issue to most people as they probably have their own specific "html2psrc" configuration
