Здравейте, имам PHP решения за печат, използващи сокети. Използване на тази функция/клас.

Всичко е наред с него, но изглежда не мога да контролирам източника на хартия/тавата, която след това принтерът избира. Някой знае ли как се прави това?
Или може би различно решение, което използвам, харесвам това, защото мога да изпратя ip адреса (няма нужда от инсталиране), postscript файла и той се разпечатва. Така че, ако има друго решение, което изисква същите неща, тогава мога да използвам това.
Използвам PHP, iis, windows. Ричард
