You're heading in a dangerous direction. It is a mistake to try to use the
despooler system to do passthrough print, for various reasons. The most
serious is that, because the despooler runs as a separate process from the
program generating the printout, and they're both writing to the same tty
device, you'll get intermixing of printer output and screen output. In other
words, it WON'T WORK reliably.

See our web site for a thorough discussion of passthrough printing:

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
